THE article in our last issue about PVC and the plasticisers and additives employed created some controversy.

There are so many armany areas of eas of modern life besides which can cause modern life health problems. besides which Some positive points have come out of the ‘debate’ so far, specifically that the can cause heating of PVC film when in contact with health problems. foodstuff is unadvisable.

All risks: Check your insurance MOST of us know by now of the dangers of cable theft, but losses incurred could be substantially more than just that of the cable ... and which quite possibly are not covered by your insurance. Two Cape Town converters received such an unwelcome surprise recently. Damage to stalled equipment and circuit boards, possibly caused during repair work, after cable leading to their plants was stolen, resulted in significantly higher claims – which were not covered in the ‘All risks’ section of their insurance policies. So it may be useful to simply check with your insurance company or broker whether you are effectively covered. Do it now!

Caution necessary PREVAILING market conditions have placed most manufacturers under pressure and most of us are looking at ways at improving systems and efficiencies, but spare a thought for those with high debt levels. Being cautious is obviously necessary, but nothing would happen if we all practised extreme caution all the time. Tempering caution is sometimes necessary to get a business operation going, but this should become less necessary as a business matures. Unfortunately this does not always apply, and the current climate has badly exposed some over-optimistic businessmen. In one case we celebrated an MBO at a packaging manufacturing business … until we heard what financial committees the buyers faced. With large sums coming off the bottom line every month, there was little chance of success. The business has since crashed and burned. Most of us will sympathize, but also remember that optimism and reliable financial planning are at opposite poles.

Plastics|SA, supported by the paper and packaging industry and under the auspices of PACSA and the Waste Management Plan developed by the Recyclers Action Group (RAG), has launched a new student design competition aimed at improving the transportation of recycled materials in urban and rural environments. Although this photo is just an example of what’s possible, try and come up with a solution that is suited to southern Africa. More info at www.plasticsinfo.co.za

SHORT SERIES COLUMNS

TO INFORM

Martin Wells

, Publisher

Articles on competition law, credit insurance, technical hints for your benefit

COMMENT

L

IKE anything else, this publication is changing with the times.

We have somewhat unexpectedly become the recipient of interest from some service suppliers to the industry. That’s not to say we have not attempted to solicit information on topics which we believe are relevant to the manufacturing environment. These parties are offering to supply columns to us about industry matters, which has led to a slight change in focus for us, as we go about producing a publication which is relevant and useful to you. In this issue we complete a series of articles about Competition Law from Adams & Adams, the Pretoria attorneys, that has proved highly interesting (page 48). You literally cannot afford to be in manufacturing – or let’s even say operation – if you are not relatively well informed about competition legislation (and specifically anti-competitive behaviour). You could get caught up in affairs that are beyond control, or – even worse – be put out of business by anti-competitive behaviour. And we have more for you! Technical ‘hints’ We are fortunate this issue to be able to begin a series of ‘Technical Hints’ columns from some of the experts in the industry. It’s not often that the ‘experts’ are happy to impart with info, partly because they tend to be very practical people and don’t in the first place consider themselves to be ‘experts’. There are important areas of the industry where we can all improve, however, and that is the goal of this series. We begin with a short column about mould safety from Bob White of Principal Plastics of Port Elizabeth

4 AUGUST / SEPTEMBER 2012

(page 20). The points Bob mentions are simple and easy to comprehend, and worth pursuing in your factory. Minimising the risk of injury to your workers is very important: besides injuries and trauma to staff, such events can hold up your whole operation.

There are important areas of the industry where we can all improve, however, and that is the goal of this series

Credit insurance While on the subject of risk, in this issue we are also publishing the first of a series of columns from Coface South Africa, one of the top providers of credit insurance to industry (page 50), about this vital topic. Paul Jooste of Coface explains the logic and strategy applied. We hear of suppliers sustaining credit failures with alarming regularity, even after practicing caution. Coface is a specialist in this area, and the points raised by Jooste could thus prove useful to you.

Momentum from sports The Olympics will be a thing of the past by the time this reaches you, but South Africans – and all Africans for that matter – were buoyed by some positive international performances by our people on the eve of the event. It’s ironic that success or failure on the sports fields is now regarded with such prominence, when the same (success or failure) applies to most of the rest of us virtually every day.

JUST BRIEFLY BOXMORE COMPLETES MCG CLOSURES PURCHASE BOXMORE Plastics has completed its purchase of the MCG Closures business in a transaction valued at over R100-million, marking the start of a new phase for the business. Boxmore has been in operation in South Africa since 1996, when it was established by its Irish parent. The company was subsequently bought by Chesapeake of the USA. A management buyout backed by Investec group took place in 2010, in terms of which the business has since been SA-owned. It manufactures preforms and blown bottles at plants in Harrismith, Cape Town and Mauritius, and needed the additional closure capacity to support those products. The MCG operations, in Samrand and Cape Town, manufacture an estimated 2.5 billion closures p/a. These businesses are to trade as Boxmore Plastics Closures. Boxmore group currently supplies about 1.4 billion preforms. www.boxmore.co.za

Servo breakthrough

by SES Johannesburg machine builder develops new servo system THE process of assembling and more recently building its own injection machines has had an unexpected spin-off for SES: it has developed a system which allows for a single servo motor to accomplish two movements during machine ‘dead’ time. Servo motors are expensive and can be difficult to operate, but the SES breakthrough allows for users to gain more performance per motor. Using a single servo motor with a servo pump, Karl Seidel and the technical service team at SES developed a system that can achieve parallel movement with separate speed and pressure from the one motor. The system allows users to gain more usage per servo motor. According to Karl,

EH WALTON CLOSES E H Walton, one of the oldest and largest privately-owned printing and packaging companies in South Africa, has gone into liquidation. Based in Port Elizabeth but selling nationally, was established in 1845, when it printed the local newspaper. It had made significant investments over the last few years, estimated at over R22-million, in order to be more competitive and the announcement of closure in April came as a surprise. The company employed about 450 people in PE.

the breakthrough has created “the platform for the next development”. Additional tasks that can be performed by the configuration include: • ejector while opening; • core pulling with mould movement. Johannesburg-based SES, which is the SA agent for injection machine manufacturer Ferromatik Milacron, has also become one of SA’s leading machine refurbishers, particularly of the older Ferromatik modules, and in 2010 it introduced its own machine, the ‘SKR’. Activity at the SES workshop in Wadeville has at times bordered on the feverish, with ‘hands-on’ MD Seidel and Daniel Roode constantly looking for ways to improve technology

Bob and Niko White have been putting lessons learned over many years to good effect at Principle, the main result being the company’s growing ability to supply automotive OEMs in a convincing manner

PRINCIPLE Plastics, one of the top automotive component manufacturers in the Eastern Cape, has been receiving recognition for its high-level supply. It has won three ‘supplier of the year’ awards in recent months, from Behr Climate Control, General Motors and VW. That’s a just reward for the team assembled by Bob and Niko White, the father and son outfit who run the business in Markman Township, Port Elizabeth. Principle was started by Niko White in late 2004, when moulding operations began with just two machines. At that stage, operating from Neave, the company did not have the capacity to supply automotive contracts and survived on small custom contracts, but how things have changed! Niko was later joined by Bob. The demise in late 2009 of what was Ariston Plastics, where both Bob and Niko had previously worked, presented an opportunity for Principle: it moved from Neave to the Ariston site at Markman and quite literally took over where Ariston had left off, resuming supply to


and develop systems that are suited to South African conditions. The process has been partly driven through SES’s cooperation with a top Austrian automation systems developer. B&R IndustrieElektronik is a master at electronic control technology, said Karl, and working with them has enabled SES to cross-refer in ‘real time’ and hence pursue these challenges at a higher level. Karl says, however, that the servo development is unique to SES. www.sescc.co.za

starts up High precision Drent-Goebel UV press used to make in-mould labels I WAS ONCE TOLD that when you are a printer you don’t exploit words that would try and convince potential customers of the print quality you promise ... if you are in printing, quality is the norm! “However, producing a quality print at a world standard is definitely an accomplishment and doing this successfully on a BOPP/polypropylene material is definitely amazing,” said Albe Naudé, COO of RenForm, owner of the new IML producer RenFlex, of Johannesburg. Ren-Flex has commenced production of IML, shrink-sleeve and wrap-around labels at its plant in Selby, Eloff Ext, Johannesburg. The entire factory is dedicated to plastic products only. Utilizing state-of-the-art printing equipment (it operates a 9-colour Drent-Goebel UV offset printing press, built in Korea) with off-line rotary die cutting capability gives Ren-Flex an advantage.

CLEVVA … from novice to experienced, quickly Mobile ‘hands-on’ coach offers the right solutions, no matter what the situation SOMERSET West-based CLEVVA, a hosted Software As-A-Service (SAAS) business, may just have cracked the proverbial code when it comes to overcoming human shortcomings, and lack of business and product knowledge with the help of mobile technology. Launched in April this year, CLEVVA is a mobile technology which essentially automates all standard operating procedures and gives the user access anywhere, anytime, enabling them to access information that allows for consistent decision-making and implementation, considers all variables and if necessary, guides them through diagnostics. The key to CLEVVA lies in being able to capture the knowledge held in a few experts’ minds and organise it so that new and existing staff can use it. We asked Ryan Falkenberg, cofounder of CLEVVA, how this can be done without new or existing staff having to personally learn through years of hardearned experience and training courses. And how do you ensure that when your key experts retire, the business does not feel the pain? Falkenberg explained that previously answers lay in offering more training, more documentation and more coaching. “We used a variety of systems to manage this journey in the hope that we could limit the risk of inexperienced staff in our business. This includes using various e-learning and knowledge management systems. In truth, none of these attempts have really worked, and even with the availability of mobile technology, research has shown that staff members don’t often access these systems while they work.” CLEVVA is the brainchild of brothers Ryan and Dayne Falkenberg (right) and their business partner Mark Pederson.

“CLEVVA is a viable alternative, one that can be used by small, medium and large businesses to capture the decisionmaking logic of their experts in a way that really helps inexperienced and undertrained staff to perform like experts,” he added. Falkenberg explained that this new breed of technology guides staff through key activities, asking the right questions, and offering the right solutions, no matter what the situation. CLEVVA allows companies to capture the expert logic required to analyse various challenges, and then provides inexperienced sales staff with an expert guide. All the user needs to do is answer the questions; the rest is taken care for them. Guides staff through key activities Flipping open his iPAD, Falkenberg demonstrated how anyone could effectively sell a wide range of technical flooring products without requiring any product knowledge. The system guides the needs analysis, recommends the right products, cross sells related products and allows you to generate the quote or order right there and then. “The technology works with any form of mobile technology, including laptop computers or smart phones and integrates seamlessly with your existing financial and CRM systems. Sales and support teams can now perform with the comfort of having all the business intelligence and expertise at their fingertips”, he

explained. Before it had even officially launched or raised its public head, CLEVVA had already received international recognition for its ability to transform and revolutionise the traditional approach to business. It was recently selected as a high impact South African business by Endeavor in 2012, a global non-profit organisation that identifies and supports innovative, high-growth entrepreneurs in emerging markets such as Argentina, Brazil, Chile, Colombia, Egypt, India, Mexico, South Africa, and Turkey. It has also successfully signed up clients in various fields and industries, including FMCG, flooring, building and construction and even commercial banks and local government and service delivery companies are eager get in on the action. “Because CLEVVA makes it easy to capture the decision-making capability of an organisation’s few experts, staff can successfully be performing activities in a very short time that previously required a number of years of experience to tackle. That means business can now scale their expertise without the long lead times of training and experience on the job. People can achieve more, with less risk and less training. Now that is a game changer”, said Falkenberg.

have enabled PTT to react efficiently to market trends: it has consistently introduced grades for specialised applications, the most recent being a new HD grade for caps and closures. It has likewise tweaked material grades for roto moulding, monofilament production and thermoforming applications. PE / PP market analysis PTT’s interest in Africa is based on the expectation that polyolefins demand is growing significantly: for example, stats suggest that an estimated 800,000 tons of HDPE will need to be imported into Africa this year alone. Demand for LDPE, LLDPE and PP appear to be large too. The PTT strategy is based partly as a result of the West-inspired oil embargo of Iran. Since the Iranians have been major suppliers of oil and polyolefins into Africa, that the shortfall will have to be obtained from somewhere else. ‘Bio’ polymers PTT’s most recent introduction is a new range of bio polymers, using naturally sourced materials. A show of hands revealed that very few in the audience had previous experience of processing such materials, but in spite of this apparent lack of experience, the PTT speaker said it was clear that anti-plastic campaigns had occurred in many countries and suggested that it would be unwise to ignore

Rothenberger donates plastic welding machine

The PTT Polymer Marketing team at the SA seminar included Thaiyaphat Jittiborripat (sales manager, Polymer Marketing DMCC); Chaipat Komolchaiamorn (GM Polymer Marketing DMCC); Narongchai Pisutpunya (executive vice-president: commercial & marketing, PTT Polymer Marketing), who was the main speaker; Supachoke Liamkaeo (president, PTT Polymer Marketing); Ms Somsri Phanichrungruang (vice-president: export sales, PTT Polymer Marketing); and Raqchao Chaowaraq and Apirasak Tregasonnoppamas (PTT area sales managers for the non-Asia region)

this trend. The campaigns against plastic bags, including levies and even bans, have led to a reaction from global brand owners, one of the most obvious presently being Coca-Cola group’s PlantBottle™ resins. PTT made a major investment in world leading bioplastics manufacturer NatureWorks last year and is working towards supplying the family of renewable Ingeo™ biopolymers made from plant sources, the main application to date appearing to be thin-wall packaging containers and fibres.

A result of the NatureWorks investment is that a world-scale PLA plant is to be constructed by PTT group in Thailand. PTT is currently also involved in a ‘bio chemical’ venture with Mitsubishi of Japan, as a result of which it is currently involved in the construction of a ‘Bio-PBS’ manufacturing unit in Thailand. So it’s clear that this is becoming a major focus for the group.

ROTHENBERGER Tools South Africa has donated a P160B plastics pipe welding machine to Plastics|SA to train the industry’s future pipe welders. According to Steven van Zyl, national sales manager at Rothenberger SA, the donation is seen as an investment in the future of the plastic pipe industry. “Specialist engineers (beyond first degree) are reportedly not produced in a quantity that is sufficient for the growth of the plastics industry. Similarly, at an operations level, plastics pipe welders and fabricators are also in short supply due to new competency demands arising from innovation and technological development. The availability of trained and experienced thermoplastics welders remains of critical importance to the industry”, he said. Manjary Subiah, regional training manager (Gauteng) for Plastics|SA, said the P1608 pipe welding machine would be used in the Thermoplastic Fabrication training. www.plasticsinfo.co.za www.rothenberger.co.za

office in East London, and a senior SARS subsequently said the ziplock bags were not levieable, but the sword of Damocles still hangs over the two companies, both of which also manufacture film and various other bags. Sequel to 2002 legislation The scenario is a sequel to the plastic bag legislation of 2002, when the levy was introduced as an environmental measure aimed at reducing plastic bag litter and intended to help boost recycling of bags. The fact that very little environmental work was ever completed appears to have had little bearing on the taxation authorities. Besides that, the entity created to manage the process, Buyisa e Bag, failed to achieve the objectives set out and was shut in June last year. Buyisa had apparently received an estimated R65-million over the duration of its existence, but had not succeeded in its objectives. Total income generated from the levy is estimated at R150-million a year.


Big growth for PET wine bottles 350% increase achieved THE potential benefits of PET packaging for wine have been under the spotlight since the introduction of the new containers, in competition with the traditional glass bottles, in 2010. Among the most common questions directed at Mpact Plastics group, which was one of the first to introduce the containers, by consumers centred on whether the “the quality will be the same”. According to Jonathan Musikanth of Mpact, it has been proven that the PET bottle does not affect the quality and taste of the wine in any way. The design prevents the absorption of oxygen into the bottle, giving the wine a shelf life in excess of two years. In economic terms, plastic wine bottles are on average eight times lighter than a traditional glass bottle. A PET bottle weighs 50g compared to its glass counter part’s 400g. This is an important advantage, meaning that up to 36% more product can be transported from a manufacturing plant to a retail outlet because the bottles require substantially less space and trucks can be fully loaded. We asked Musikanth how the new containers have been faring:

How successful has the launch of these containers been, in terms of market penetration? We have seen successful launches of several brands locally and for export in 750ml. Several customers have used our bottles including brands such as Backsberg, Boland, Simonsvlei and most recently Van Loveren. These 750ml bottles are available in many of South Africa’s major retailers, while the 187ml bottle has been successfully used on local flights such as SAA and international airlines. We have recently launched our new 1 litre bottle. By how much have volumes increased? Volumes have increased by 350% from 2011. Have there been any new/further technology advances? Since 2011 we started to use recycled content (r-PET) in our products. Currently 25% of the bottle is made-up of r-PET and together, with our partners, we are looking into ways of increasing this percentage.

The Wine & Spirit Board approved the use of PET for South African Wine of Origin certificate use in 2010, when one of the first varietals introduced was the ‘TreadLightly’ range of wines from Backsberg of the Western Cape

hopes to boost industry growth Stakeholders believe fair will boost industry’s international exposure KEY role players in South Africa’s tooling, precision engineering, mould making, design and application development industry are looking to the annual AfriMold trade fair to play an important role in supporting, growing and developing their industry. The annual AfriMold trade fair takes place from 10-12 October at the Gallagher Convention Centre in Midrand. Stakeholders are unanimous in their support of the fair and believe it will give a boost to an industry that, like so many others in this economy, is experiencing slow growth and could use international exposure and input to enhance its competitiveness and relevance.

Victor Stiehler of Hestico, supplier of machines, ancillary equipment and components to the plastic, rubber & packaging industries, elaborates: “The tooling industry is busy growing slowly but surely, however it will still take a while before it gets to the level that it can and should be at. The fact that the big OEMs go overseas to have tooling made there, rather than here, is a problem. The toolmakers in South Africa must rebuild trust with their customers so they can build tools for them again.” Star Tooling is another exhibitor that believes AfriMold will add value to both the industry as a whole and to its business

Waste not, want not NAMPAK Flexible says it is currently producing some exciting results in the multi-layer plastics recycling arena through projects that focus on absorbing plastic waste from their operations. Nampak Flexible recently activated a unique sorting and streaming system for all of its post-industrial waste to allow maximum recovery and reprocessing back into products through various technologies and processes. One process makes material available to NGOs where it is ‘up-cycled’ into a range of products that can be produced for customers. Examples of such products include bags, bowls, collapsible bins, benches and pallets to mention but a ‘few’. Nampak Flexible is even using

technology to reprocess its own waste for reuse internally by making pallets that are currently being used in the company’s warehouses as an alternative to wooden pallets. But the recycling of this waste is not just an environmental issue; there are social and economic benefits for NGO’s and local communities too. Nampak Flexible is also looking ahead at opportunities to supply schools with injection-moulded chairs produced from post-industrial flexible waste; the company is already involved with a similar project supplying kids tables and chairs to crèches in the local KwaZulu-Natal area. www.nampak.com

in particular. Says the company’s Chris Schmid, “I think there is potential at a fair of this nature for industry players to identify and meet the correct partners, should this be the objective.” Several industry players are also looking to AfriMold to support their initiatives to enter into joint ventures and partnerships with foreign companies. Toolquip and Allied’s Maurice Lockwood points out that the main benefit of exhibiting at AfriMold is “because it is aimed at a specific area of the industry”. The company will be using this uniquely targeted opportunity to exhibit a CNC machining centre, Baty 3D vision master camera based inspection equipment, CNC training simulator and small tools at AfriMold. The AfriMold conference, which runs alongside the exhibition and is presented by the Tool Making Association of South Africa (TASA), will address the role of science in elevating current practice to the domain of leading economies. The conference will bring to its delegates a high level of technical knowledge, together with important issues such as production management; intellectual property and registered designs, effective business and legal contracts; global competitiveness; training; skills development; and employment creation. www.afrimold.co.za

MOULD SAFETY: Inter-related settings need to be considered BY BOB WHITE, PRINCIPAL PLASTICS MOULD SAFETY, a very important part of setting moulding machines, is often neglected because it’s misunderstood. Mould crashes are expensive and usually avoidable. To achieve optimal mould safety on machines, a number of inter-related settings need to be considered: 1) Position: To identify the correct position for the mould safety phase to begin, close the mould slowly and stop where you consider the safety zone should start. For instance, where angle pins enter slides, or where a part that hasn’t fallen out fully could jam. Input this position. 2) Pressure: Close the mould with the lowest possible pressure in the mould safety zone. This might sound obvious, but it’s surprising how many machines are not set properly in this zone. To ensure lowest possible closing pressure is set, it might be necessary to increase mould safety timer temporarily. 3) Speed: Set an appropriate closing speed. Closing too fast may not allow the machine time to react if there is an obstruction, and damage may occur even at low clamping pressure. 4) Timer: Set the timer to be just a fraction of a second longer than the actual clamping time (in mould safety zone) needed. Some make the mistake of setting this timer according to the total mould closing time, which of course is much longer. 5) Re-check: Once all the above has been set, check again, as each adjustment affects the other settings. To help explain mould safety on the shopfloor, ask whether the Setter would rather be pushed against a wall by a charging elephant, or a mouse? Also, how long would he like the charging elephant to press? Happy moulding!

Student design competition will explore rural transport Competition focuses on transportation of recycled materials in urban, rural areas AS PART of the International Year of Energy and the German South African Year of Science, Plastics|SA, supported by the paper and packaging industry and under the auspices of PACSA and the Waste Management Plan developed by the Recyclers Action Group (RAG), has launched a new student design competition aimed at improving the transportation of recycled materials in urban and rural environments. The competition is open to students at Tshwane University of Technology, University of Johannesburg and Wits Engineering Faculty. The objective is to ensure that the recovery of plastics packaging materials for recycling increases and to promote separation at source from households. POLYCO, Plastics|SA and the Plastics Institute of SA (PISA) are sponsoring the Student Design Competition 2012. Entries should be submitted by 30 September and the winners will be announced in October at the Afrimold Exhibition at Gallagher Estate. It is envisaged that the winning concepts will also be exhibited at Euromold in Frankfurt in November. The Fraunhofer Institute for Surface Engineering and Thin Films (IST) and the Fraunhofer Institute for Transportation and Infrastructure Systems (IVI) will provide students with the opportunity to engage with institutional specialists should their technologies be identified for incorporation in the concepts. Concepts for mobility According to Douw Steyn, Plastics|SA sustainability director, there is a major need in the developing world in general and South African rural areas in particular, for a mode of transport for the rural poor to collect recyclable material and transport this to the collection station or depot, such as buy-back centres of recyclables. “The SA plastics industry has made major inroads in the collection of plastic waste material and has

established a recycling industry to keep these materials out of the waste stream. The project needs to be extended to the rural areas to prevent pollution and provide opportunities for entrepreneurs to establish themselves, providing this vital service to the community,” he adds. Steyn said that entrants are encouraged to come up with concepts for mobility, be it human, electric, biogas or solar powered which could be a radical game changer in the developing world. The liberal use of plastics is encouraged, specifically if the concept mitigates mass manufacture and it needs to be light weight in construction. “We encourage the lateral thinkers to analyse the problem and propose workable solutions. Clearly, athletics and functionality play a role, and the winners will differentiate their designs from the mundane!” The following must be incorporated in the students’ overall project design and product: The use of plastics or plastics composites A mode of transportation capable of rural mobility Energy efficient Lightweight but capable of transporting up to 150kg Capable of mass manufacture Aesthetically appealing Must help plastics recycling recovery www.plasticsinfo.co.za AUGUST / SEPTEMBER 2012 21

HIGHLY SPECIALISED

PU foam formulator keeps it secret THERE’S a secret place at high-density polyurethane manufacturer General Plastics’ plant in the USA where no-one but employees sworn to secrecy is allowed. That’s where the company formulates its highly specialised PU foams, materials that are used in some extremely high-tech and high-performance components. With a history dating back to 1941, General Plastics (GP) makes highly specialised foams for the aircraft, composite lay-up tools and cores, marine, medical, thermal insulation, solar/wind energy, sport and other sectors. One of its most unusual products is Last-a-Foam® materials for insulation of nuclear containers, possibly one of the most demanding applications for foam yet. GP began as a manufacturer of preservative coatings for wood and other organic materials and later expanded into fabricating phenolic-resin-impregnated composites for aircraft and commercial uses. It subsequently began producing coatings for fire hoses, through which it became involved in polyurethanes. Company founder LW Schatz saw an opportunity in specially formulating of PU material. It began manufacturing foam blocks which could be used for a wide array of aerospace applications, and then began fabricating parts for high-performance structures. The latter is what attracted the attention of Graham Blyth of Aerontec of Cape Town: he noticed that GP had a grade of rigid or flexible PU foam for applications which in some cases were

previously unserviceable for the material, including composite core, blast mitigation, solar energy, signage, tooling and moulds and other markets. Kirk Lider, head of sales & marketing at the USA company, recently visited South Africa as a guest of Aerontec and outlined some of their technology advances. “We take the stress out of it,” said Lider,

outlining how GP’s foam structures have become increasingly application specific. For example, it produces a foam for ice hockey sticks which have to absorb high impact hits, rigid PU board for the flight deck of the new Boeing 777 plane (GP material is Boeing-specified) and high-temperature tooling boards. In some cases the foams are integral skin, in other supplied in block forms. With this kind of specialization, it is necessary for GP to keep its proprietary formulae confidential, hence the secrecy practised in the mixing section of its plant. GP currently employs over 150 skilled professionals at its plant in Tacoma, Washington state, on the west coast of the USA. It produces high-temperature and industry standard tooling boards, thermal insulating bearing blocks, flexible seals, nuclear containers and a variety of aerospace and military custom applications. Today its focus is on solving problems for customers through unique products and chemical technology.

USA’s new composite jet fighter A prototype of the United States’ new jet fighter, the F/A-37, underwent catapult fit checks for aircraft carrier launch recently. Officially known as the ‘Air Vehicle Number 1,’ the plane makes extensive use of high-tech composite solutions to reduce weight and improve performance. Although specs are classified, the super-cruise stealth fighter/bomber/interceptor is believed to be Mach 3.5 (top speed in the Mach 4 range) capable with a range of approximately 4000 nautical miles (about 7400kms)

A steering committee is driving the process forward and has taken on the responsibility of developing a strategic business plan that will be presented to the stakeholders. “They have identified various objectives they would like to achieve during the short to medium term, such as investigating the pelletizing of polystyrene and the use of polystyrene in building projects. Zimbabwe is hoping to achieve PS recovery rate of 20% of total volume per annum and to set up a recycling programme first in Harare, followed by the rest of Zimbabwe. However, they are kickstarting their shortterm activities by introducing the PSPC’s cooking bag project (in which recycled polystyrene is used for cooking bags) to

Tangential mixer technology developments New HF rubber mixers achieve major output increase THE ability of rubber mixing specialist Farrel to achieve a major performance boost in its Banbury® compounding equipment was illustrated in a presentation by Ian Latchem at an IOM³ function in Port Elizabeth in June.

ing Group’s impressive new technology centre in Freudenberg, Germany, where a range of equipment has been installed specifically for R+D both in house and as a facility for our customers to develop their products and process methods from laboratory stage through to automated production runs.

Latchem, who is based in the UK, worked in South Africa with Carst & Walker as a service engineer in the 1980s, servicing Farrel equipment and later as a product manager representing numerous rubber related manufacturers. He subsequently returned to the UK and joined Farrel, inventor of the Banbury® mixer. Farrel has since become part of Harburg-Freudenberger Mixing Group (HF Mixing Group), which was formed following the merger of some of the top mixing equipment companies in the West, including Farrel, Harburg-Freudenberger and Pomini. Carst & Walker is the SA agent for HF Mixing Group, which is the second largest mixing equipment manufacturer in the world, after Kobe of Japan. It has developed a reputation for focusing on continued R&D partnering with major rubber producers. Ian’s presentation was effectively a report on the technology progress made in the last few years – and significant advances have been made. Most of the research work is conducted at HF Mix-

Even-speed rotors New developments include even-speed NST rotors: four wings on the rotors are specifically designed each with a specific function to optimise distribution and dispersion, eliminating the need for the oldfashioned 2-wing friction ratio rotors. The development also improves batch to batch repeatability and speeds up mixing, temperature control has been improved with force tip cooling that improves efficiency in silica/silane compounding by drastically reducing heat buildup. The end frame has been redesigned, vastly improving access to dust rings. Dust seals now have three cylinders per seal giving an equal pressure distribution over the seal face for improved performance, the drop door is now wider, which allows for faster discharge, enhanced cooling and virtually eliminates material hang-up. Hydraulic hoppers are standard being accurate and reproducible. Intelligent ram control – variable ram speed and position controller eliminates need for a ram sweep, thus saving time and energy.

New IOM³ national committee Craig, in what is now an appointed role. Since Richard Blyth left the position about two years ago, the secretarial functions became part-time jobs of NEC members, so it’s hoped this will assist in improving the service to IOM³ members. André takes over as chairman from Hans Strydom, who did an excellent job during his tenure – in spite of the challenge of opening his own business, Rubber Nano Products, during the period.

ANDRÉ Cornelius of Orchem Trading is the new chairman of the Institute of Materials in South Africa. The new IOM³ national executive committee comprises Jaco Smith as vice-chairman (also KZN chairman); Coen Burger (Eastern Cape chairman); Spike Taylor (Northern branch chairman) and Georg Cronje (also Northern branch), as treasurer.

Simplify your business, and remember to have fun! Observations of business in California and cruise on carrier

Steve Mountain (right), the speaker at the Western Cape AGM, with Dudley Flugel of Nedbank, sponsor of the evening, and branch chairman Billy Macmillan

KEEP your business simple, and remember to leave time for fun! That was the unexpected (but important) message from Steve Mountain in his address at the AGM of the PISA Western Cape branch on 26 June. Formerly MD of Plastamid, the material supply business, Steve had taken ‘early retirement’ some years ago and set up a consultancy business, covering mainly the chemical and manufacturing industries. That’s also given him the opportunity to observe business strategies from a dis-

tance, something which he has long been interested in. He was able to take the process international during a recent three-month visit to California in the USA, where he made ad hoc observations of American business strategies. In Steve’s view, the Americans have got a positive attitude towards running businesses. A lot of middle-aged businessmen as well as start-up businesses have had to come up with novel strategies since the financial downturn of 2008. Stationing a few machines adjacent to retail outlets to make packaging containers on demand is, for example, now considered a very viable solution in the state. And many small businesses are now active in the wind and solar energy sector, with photovoltaic solutions being the preferred choice. California, incidentally, has a similar climate to that of South Africa, with a lot of sun and wind! Californians appear to approach training with enthusiasm and possibly even more enthusiasm towards applying those skills actively, says Steve. A business-minded culture prevails: in fact, it’s generally expected that young people in California will start businesses … and if it fails, the ethos is to put that behind you and start again!

The American system, says Steve, makes it easier to get started. But the opposite side of the coin is that it’s also easier to get fired. By that he means that “accountability” is a recognised aspect of industry in the USA: meaning that if you don’t measure up you’re probably going to get the chop! But, rather than dwell on the losses, the culture suggests it’s preferable to avoid the labour legislation route, get into business and, just as importantly, make sure you’re having fun. With that aspect in mind, Steve also managed to get a berth on the USS Carl Vinson, a nuclear-powered aircraft carrier in the United States Navy’s 5th Fleet, on a cruise from Hawaii back to San Diego on the US west coast. Besides enabling Steve to tick one more item off his ‘bucket list’, this gave him the opportunity to view the Americans’ awesome firepower. • SHOULD READERS WANT MORE INFORMATION ABOUT THE PRESENTATION AND EXPERIENCE, STEPHEN CAN BE CONTACTED AT stephen@ladibird.co.za OR 083 255 7068. • THANK YOU TO NEDBANK FOR SPONSORING THE FUNCTION.

The pride Americans take in their armed forces is possibly difficult for people in South Africa to comprehend, but the scale of armaments isn’t. The USS Carl Vinson aircraft carrier, which Steve Mountain joined for a 5-day cruise in the Pacific, has a staff complement of over 5000 and carries over 70 warplanes … plus its accompanying fleet includes a nuclear-powered submarine (which leads the sailing formation) as well as a number of destroyer and attack craft. Steve was able to witness the simultaneous launching of planes (where a plastic coupling on the catapult drew his interest, but which he wasn’t able to learn anything of); a sound barrier-breaking flyby; the tense moments of return landing … and was also roped in for firefighting drill.

With a Master of Commerce degree specialising in local economic development, Andrew writes columns for the ‘Natal Mercury’ and the ‘Witness’ newspapers. He was principal of Alexander Boys School in Pietermaritzburg prior to joining the Durban Chamber. Andrew’s predictions for KZN for the near future are that the province’s economy will grow and be of interest for business investors, especially if the proposed dugout harbour for container ships goes ahead as planned.

IFPA uses identification stamps to ensure quality installations Welder Identification System allows for a welder to be traced back to every weld he has ever done

A welder applies his unique IFPA identification stamp after completing a weld

IN A MOVE to ensure consistent high quality of welding and introduce transparency and accountability in the industry, the Installation and Fabrication Plastics Pipe Association (IFPA) has issued all of its welders with identification stamps. According to IFPA Chairman, Mike Smart, its welders were required to be recertificated before they were issued with their unique stamps.

“The annual recertification of welders was instituted by the Plastics Federation (now Plastics|SA) in 2000 in an effort to better ensure quality of practical work. However, in September 2010 it has been decided that IFPA members would have the benefit of only having to recertify their welders once in a three year renewal cycle, while A closer look at non-IFPA members the IFPA would be required to cerwelder tify their welders annually”, identificasays Smart. tion stamp As part of IFPA’s mandate and mission to ensure that its members adhere to the Association’s objectives of ensuring consistently high standards of plastic pipe fabrication and installation, they felt it necessary to also develop a mechanism whereby a welder could be traced back to every weld he has ever done. A Welder Identification System was implemented by Plastics|SA and IFPA in 2010.

stabilizers that are non-toxic to humans. Calcium/zinc stabilizers have been used in PVC applications for more than 25 years and, in addition to being non-toxic, they are essential elements to the human body. Organic-based stabilizers are predominantly based on uracyl technology and are heavy metal and odour free, and approved for potable water and food contact applications.

Heavy metal free! SA pipe industry 100% lead-free LEAD has been eliminated from all locallymanufactured plastic pipe products and all plastic pipes manufactured by the Southern African Plastic Pipe Manufacturers Association (SAPPMA) are guaranteed to be free of heavy metals. “We embarked on this journey in 2006, as a voluntary policy of heavy metal free stabilizers for the manufacture of PVC pipes. The reason for the initiative was based on health and environmental considerations and we are immensely proud of having reached our goal of eliminating all lead stabilizers from SAPPMA members’ piping products five years ahead of the anticipated European Union (EU) targets”, said Jan Venter, CEO of SAPPMA. As a member of the Southern African 36

“Since then, every IFPA welder has been issued with a unique number, printed on an identification card, along with his photograph. Each IFPA Member Company is expected to compliment the system of traceability with the use of a stamp on each weld, displaying the IFPA company number, the unique welder number and the IFPA logo”, Smart explains. The stamp is made of special hardened steel and can be used next to a weld if the weld surface is too small. Members are tasked with the responsibility of ensuring the stamps made for their welders are kept up to date; to verify the specific discipline that the welder has been qualified for and control employee activities such as moonlighting. These are not the responsibility of IFPA. Concludes Jan Venter, CEO of SAPPMA: “IFPA is an initiative of SAPPMA and was formed with the view to expand regulation of the Plastic Pipe Industry in Southern Africa. We fully support and endorse this programme that proves our commitment to go further on the quality value chain. This move has also been welcomed and applauded by customers who appreciate the level of transparency and accountability we try to introduce and maintain in this highly specialised industry”.

3rd Revision of SAPPMA technical manual now available THE Southern African Plastic Pipe Manufacturer’s Association (SAPPMA) has published and released a third revision of its Technical Manual, aimed at assisting engineers who are involved in the plastic pipe industry to make informed decisions. “The purpose of this manual is to provide basic, relevant information and the guidance needed to ensure that plastic pipes for water supply and waste-water disposal applications are correctly specified and selected”, explained SAPPMA chief executive officer, Jan Venter. Although this manual does not attempt to replace published text books and codes on the subject, Venter said that it is a basic guide to the use, selection and specification of these products. It covers the differences between the various types of plastic pipes and the basic procedures for determining product size, strength and material properties for a range of applications. The latest revision also includes sections on hot and cold water plumbing pipes, HDPE fabricated fittings as well as the jointing of HDPE. For a limited period copies of the publication have been made available to design and civil engineers free of charge via SAICE and as a service to the industry. “Poor quality plastic pipe is not necessarily obvious from a visual point of view, which makes it even more important for design engineers or specifiers to apply all available precautions in the selection of manufacturers, suppliers and installers”, Venter said, adding that pipe manufacturers and installers who are members of SAPPMA and IFPA are subjected to additional quality control measures over and above the national standards. • THE TECHNICAL MANUAL COSTS R150 AND CAN BE BOUGHT BY CONTACTING LOUISE MULLER ON ADMIN@SAPPMA.CO.ZA

Gigantic glowing fish sculptures made from recycled PET bottles are making Rio de Janiero’s beaches even more of an attraction than they usually are! The scales of the epic sculptures are made by lining up hundreds of empty clear plastic bottles, giving the fish a shimmer day and night. The glowing installations appear on the popular Botafogo Beach as part of the Rio +20 conference. The sculpture, created for the UN Conference of Sustainable Development (Rio +20), brings awareness to both the importance of recycling, and its relationship to marine life.

The M2 LaserCusing System’s primary The only one of its kind in the country, the application is the production of complex system has been installed at the Institute of tooling inserts for metal moulds used in Advanced Tooling (IAT), hosted within the various industries. Moulds are routinely Rapid Product Development Laboratory employed to manufacture products made in the university’s Department of Industrial from a variety of substances, such as

plastic, glass and metal. In addition, the machine can also be used to manufacture advanced metal components for utilisation in the aerospace, automotive, medical and dental industries. This wide range of applications facilitates synergies between numerous research, development and industrial projects. “This machine can produce components that cannot be made in any other way. It allows for complete design freedom. Whatever can be imagined, can be built with this system,” said Professor Dimitri Dimitrov, head of the Rapid Product Development Laboratory at Stellenbosch. He also acts as mentor at the IAT. One of the machine’s major advantages

Complex parts with extremely fine detail and tolerances are achievable. These parts were produced during the commissioning of the machine. The part on the right is about 30x30mm and 40mm high. The small gaps are 1mm to 2mm and even less in some places. None of the parts are bigger than 60mmx60mm. However, the build possible on the machine is 250x250x280mm 42 AUGUST / SEPTEMBER 2012


Inserts for this mould, produced on the system, would have been extremely difficult to produce with existing technology; the mould is being used to produce a cutlery drainer rack

is that it can process a wide variety of metals, such as aluminium, stainless steel, various hot-work tooling steels, titanium, cobalt-chrome and nickel-based alloys. Dimitrov pointed out that although the machine can build 3D metal objects, it should not be confused with 3D printing. “This system also uses an additive process, but it is not the same as 3D printing. In printing, a substance is laid down layer by layer, and an object is built up by using binder liquid jetted by a printing head. With this machine, metal powder is fused by laser. It is basically selective melting and micro-welding by laser.” The system was developed and made by Hoffman Innovation Group AG, a leading German tooling producer. The term LaserCusing is made up of the letter ‘C’ from ‘concept laser’ and the word ‘Fusing’ for ‘complete melting’. The manufacturers describe the system as ‘the technology of the future’. The metal powder used in the system

The M2 LaserCusing System can produce complex structures by fusing very fine metal powders at high temperatures of about 1000ºC

consists of extremely fine granules of 20-40 microns each. The laser fuses them at temperatures of above 1000°C. And it does so in very thin layers of 20-30 microns each. The system will be used for advanced research purposes by post-graduate students at SU and IAT tooling engineers. In addition, the system will service the tooling industry, which will help create employment opportunities and stimulate economic growth. The system can provide a productivity improvement for various moulding and casting processes of about 30% through cycle time reduction. “The SSME sector now has access to an advanced manufacturing capability for the production of complex tooling inserts and other objects. Before, they would have had to go overseas; now they can do it right here. Local industry has already shown

significant interest in this advanced technology,” said Dimitrov. The funding application to the TIA was supported by the Tooling Association of South Africa (TASA), which recommended the equipment to support the industry through cutting edge technologies. The advantages that the system brings to the industry and research community alike are in line with the objectives of Stellenbosch University’s HOPE Project, which uses the institution’s academic and research excellence to tackle developmental challenges in society. • INQUIRIES: MIKE SAXER, MIKESAXER@SUN.AC.ZA www.sun.ac.za AUGUST / SEPTEMBER 2012 43


MORE THAN JUST PE & PP

PRODUCED IN MIDDLE EAST

The most visible use of PET in the Middle East is packaging: water, fruit juice and carbonated soft drink bottles, thermoformed trays, barrier films and blister packs

Largest non-polyolefin polymers produced is PET three plants produce more than 2 million tons a year BY DR NIALL MARSHALL

FEATURE

WHEN the polymer industry was started in the Middle East in the 1980’s it was to take advantage of the readily available feedstocks that were a by-product of oil production, namely ethylene. Today polyethylene and polypropylene account for almost 90% of the plastic produced in the Middle East. However, the slate of new feedstocks that are becoming available from the new petrochemical complexes are diversifying the range of polymers produced in the region. And even if only 10% of the millions of tons of polymer produced annually are not polyolefins, it is still a lot of polymer! By far the largest of the non-polyolefin polymers produced is PET (polyethylene terephthalate). Just three plants (in Oman, Saudi Arabia and U.A.E.) produce more than 2 million tons per year and planned expansions and debottlenecking will increase that total further by 2013. There is also a 420 000 tpa plant scheduled for start-up at the end of 2012 in Egypt and plans for another 800 000 tpa plant in Saudi Arabia was announced last year. The most visible use of PET is packaging: water, fruit juice and carbonated soft drink bottles, thermoformed trays, barrier films and blister packs. Not surprisingly these are also the main uses in the Middle East. But PET, when it’s not ‘PET’, is ‘polyester’ made into fibres. Some of the polyester is used in the region to make carpets, textiles, nonwoven fabrics and tyre cords although polymer chips are also exported. 44 AUGUST / SEPTEMBER 2012

But, unlike most other polymer produced in the Middle East and exported, not all the PET that is exported from the region is exported as a raw material – PET and APET sheet for packaging is exported globally. In fact Octal Petrochemicals in Oman is the largest producer of PET clear rigid sheet in the world. Surprisingly PVC is not produced in large quantities - only about 500 000 tpa in Saudi Arabia and Egypt, although both emulsionand suspension-PVC is produced. Most of the PVC used in pipes, membranes, wire and cables is imported into the region although vinyl chloride monomer (used to make PVC) is produced in Qatar and exported to Asia. Polystyrene is produced in Saudi Arabia and there is also a plant under construction in Egypt. The polystyrene (GPPS, HIPS and EPS) is used mostly to make thermoformed and injection moulded packaging and houseware in the region. Another styrenic polymer, ABS, will also be produced in Saudi Arabia from 2014 on a new 200 000 tpa plant. Another family of polymers due to be produced in Saudi Arabia in the near future are elastomers and synthetic rubbers. In 2015 a 400 000 tpa plant comes on-line producing a range of butadiene rubbers (used in tyres and gaskets) and EPDM (used in seals, membranes and automotive applications). With the acquisition of GE Plastics in 2007, SABIC became one of the major world producers of engineering polymers with a range that included ABS, polycarbonate, acetal (POM) and polyamide. Prior to the purchase of these manufacturing assets SABIC didn’t produce any of these polymers although a polycarbonate plant, which has since started production, was planned for Saudi Arabia. Polycarbonate is used in

applications as diverse as electronic components, light housings and skylights, all of which are manufactured in the Middle East. Polycarbonate is also used in optical media – CDs, DVDs and Blu-ray discs - which is a small application in the region and grades for these uses are exported from the area. Not all the planned new polymer plants are the mega-scale plants usually associated with the region. SABIC has announced plans to produce acrylic (PMMA) for the construction, appliance and medical device market on a new 50 000 tpa plant. PMMA is also used in skylights, signs and glazing and is used extensively in the region and so it is expected that a significant portion of the new plant’s production will be used in the Middle East. Another polymer that SABIC is due to debut Saudi production in 2013 is acetal (POM) which is widely used in moving parts where its dimension stability and wear resistance are valued. As for polyamide: the Chevron Phillips joint venture in Saudi Arabia has announced plans to produce PA 6,6 and SABIC has also expressed their interest in building capacity in Saudi Arabia – but for now the ‘nylon bag’ at the supermarket is still polyethylene!

The technique has, however, since been used in chromatography to analyse mixtures of gases, liquids and dissolved substances. Dr Lusi and Prof Barbour have now simplified this separation method by using a nickelbased metal complex as their host structure, and exposing the polycrystalline material to xylene vapour. It allows them to separate the three different xylene isomers much faster and more effectively, all in one process. “This method seems promising to implement in industrial scale applications, such as pressure swing adsorption (PSA) processes that use a substrate with prioritized selectivity,” he explained. Their findings have been patented, with the help of the University’s INNOVUS office. “Now it’s up to the engineers to prove that it can be used in a large scale production process,” Prof Barbour added.

Marine debris body to advice Plastics│SA PLASTICS│SA has held its ďŹ rst meeting of the newly formed ScientiďŹ c and Technical Advisory Panel on Marine Debris. The Marine Debris Panel was created to look into the issue of persistent plastic debris in the coastal and marine environment and will advise Plastics│SA’s Sustainability Council and other stakeholders on awareness and research concerning marine debris in South Africa. “The problem is gargantuan and due to the unseen scale of the issue at sea it needs more attention in South Africa as our partners in other countries have already stepped up the effort to address this issue,â€? said John Kieser, Plastics/ SA environmental manager (coastal provinces). “Most people are only aware of the issue when it is on the coast, but it is a fraction of the amount of plastic already at sea. This dovetails into Plastics│SA’s other efforts to increase recycling of plastic products in South Africa and to design material not just for recyclability, but also in such a way that the packaging or parts of it does not become an entanglement problem. What is also clear is that by focusing on the concern at sea, the matter of littering further inland is also addressed in a way.â€?

DESIGN

IT’S A FIRST ! Tritan thermoplastic copolyester from Eastman has never been used commercially in SA before JOBURG-BASED snapp Design is an award-winning distinctive lifestyle brand which aims to highlight contemporary design in South Africa by producing innovative products. “The possibility of having a subtle impact on humanity through inspirational products was our motivation when we created our own brand,” said Jonathan Fundudis, owner and head designer at snapp Design. When Jonathan and business partner Renko Nieman, with qualifications in industrial design and mechanical engineering respectively, formed snapp, their quest was encouraged by the process of discovery, redefining products through new understandings yet remaining true to self.

AUGUST / SEPTEMBER 2012

By using the extruded form of Plasticine and manipulating it by creating a gentle ‘s’ curve and separating the blended profile forms into tines, snapp Design were able to create an intriguing and functional utensil to mix and serve salad

“With our background in industrial design, the development of our ‘splay’ salad servers was a milestone for our company as it was the first plastic injection moulded product we produced,” said Fundudis. Designed by David Holgreaves, an industrial designer who works for snapp Design, the inspiration behind the salad servers was derived from the material that was initially used to explore various concepts, Plasticine. “By using the extruded form of Plasticine and manipulating it by creating a gentle ‘s’ curve and separating the blended profile forms into tines, we were able to create an intriguing and functional utensil to mix and serve salad,” said Holgreaves. Once the development of the product was completed, snapp approached Plastichem for their expertise and technical support and set a brief to explore plastic polymers with which to produce the salad servers. The appropriate material that was defined is not only a first for snapp but a first for South Africa too, as this particular thermoplastic has never been used commercially here before. A copolyester called Tritan from Eastman, supplied locally by Plastichem,


was the suitable solution. Wizard Plastics was commissioned to do the converting and found the copolyester effortless to process. “We felt Tritan ticked all the boxes for the specified requirements of ‘splay’: the first being that it is FDA-approved as the product comes into contact with food, as well as being BPA-free. Secondly, for the convenience of the user, the material is dishwasher safe. From an aesthetic point of view, it has a clear base: therefore we are able to achieve vibrant colours from However, Tritan offers a variety added pigments as well as giving us the of processing, performance and option of being glass-clear with a high sustainability advantages over PC – and gloss finish. other clear polymers such as SAN and Because of the intricate design where SMMA – in a variety of housewares the tines split off applications. from the handle, the Eastman Tritan Because of the intricate inherent toughness of copolyester provides design where the tines Tritan prevents any a unique balance potential breaking split off from the handle, of these properties, of these delicate allowing you to the inherent toughness structures. create differentiated of Tritan prevents any “A material that products with potential breaking of these has certainly added compelling value: value to a simply delicate structures. glasslike clarity, beautiful product toughness, chemical where functionality and aesthetics blend resistance, processibility, hardness, BPAto create something special, it may be free, tintability, surface gloss, strength, a first for both companies locally – yet heat resistance, economics, design I’m positive it wont be the last,” added flexibility.

What is Plasticine? PLASTICINE was formulated by art teacher William Harbutt of Bathampton, in Bath, England, in 1897. He wanted non-drying clay for use by his sculpture students. Although the exact composition is a secret, Plasticine is composed of calcium salts (principally calcium carbonate), petroleum jelly and long-chain aliphatic acids (principally stearic acid). It is nontoxic, sterile, soft, malleable and does not dry on exposure to air. It cannot be hardened by firing; it melts when exposed to heat and is flammable at much higher temperatures. Commercial production started in 1900 at a factory in Bathampton. The original Plasticine was grey, but the product initially sold to the public came in four colours. It was soon available in a wide variety of bright colours. The original Plasticine factory was destroyed by fire in 1963 and replaced by a modern building. The Harbutt company continued to produce Plasticine in Bathampton until 1983. It is currently made in Thailand.

Filling hot dessert sauces

Lightweight 187ml PET wine bottles

LIOTTA dessert sauces are filled while hot, which places high demands on its packaging. A new 800ml bottle manufactured by the Austrian packaging specialist Greiner Packaging International meets these demands. The company opted for Greiner Packaging International and its Carinthian location of Wernberg. Since this spring, extrusion-blown bottles with a volume of 800ml have been supplied to Liotta from Wernberg. The new packs are made from PP specifically developed for the hot filling process. The core of production at Liotta is a fully-automatic, microprocessor-controlled unit that combines efficiency, hygiene and accuracy. At the beginning of 2012, the company was certified in accordance with the IFS (International Food Standard). All production processes are monitored at relevant check-points according to the HACCP (Hazard Analysis and Critical Control Points) concept, and verified. Greiner Packaging International also runs an HACCP programme.

BRONCO Wine Co., Ceres, Calif., a major supplier of varietal wines, is establishing a strong position in the single serve, 187ml wine category with the adoption of lightweight PET bottles from Amcor Rigid Plastics. Bronco, the fourth largest winery in the U.S., recently made a major packaging switch from glass to further penetrate the retail and airline markets and capitalize on PET’s glass-like clarity, portability, sustainability advantages and reduced cost. A unique barrier coating technology developed by Germany’s KHS Plasmax GmbH affords the 187ml PET container an extended shelf life. KHS Plasmax® Silicon Oxide (SiOx) barrier coating is a glass-like material which seals the container from the inside to protect the contents from oxidation. This ultrathin (less than 100nm) material is transparent and resists cracking, abrasion and delamination. It does not degrade over time nor limit the storage time for empty bottles. The barrier coating is easily removed during the recycling process and does not contaminate the recycling system.

Zoff SMART frames made with SABIC Innovative Plastics’ Ultem resin meet the Japan Standard Association JIS B 7285 standard, whose testing includes 20 000 bending repetitions

INTERMESTIC Inc., of the USA, a specialty retailer of eyewear and accessories, has chosen tough, lightweight Ultem polyetherimide (PEI) resin from SABIC’s Innovative Plastics for the frames of its new line of Zoff SMART eyeglasses. The tailored, aerospace-grade Ultem resin material solution helps meet Japanese consumer demands for fresh, new eyewear styles with exceptional long-term performance and feather-light comfort; by allowing Intermestic to eliminate titanium and aluminum from the material selection process. The Ultem resin also provides exceptional flexibility, flame retardance, and resistance to chemicals, heat and ultraviolet

(UV) light, as well as greatly expanded design freedom, which enabled Intermestic to create stylish, eye-catching frames for sophisticated consumer appeal. Ultem resin delivers a broad range of desirable performance properties for eyeglass frames. The material offers elasticity coupled with resistance to deformation, allowing the frame to be bent easily yet returned to its original shape. Zoff SMART frames made with Ultem resin meet the Japan Standard Association JIS B 7285 standard, whose testing includes 20 000 bending repetitions (opening and closing the frame). The SABIC resin’s dimensional stability ensures that the lenses are retained in

How to reduce noise from polymer roof sheeting A READER inquired about the problem of noise produced by the expansion and contraction of polycarbonate sheet in exterior applications. When exposed to sunlight, PC sheet produces creaking sounds as it expands while heating up and again as it contracts later in the day. We asked Colin Coetzee, former CEO of Ampaglas, SA’s leading manufacturer of polycarbonate sheeting, about this problem and he confirmed that the question was valid: PC expands and contracts at about 3 to 4x that of steel (polyethylene sheet has even more pronounced behaviour, being a factor of 5-6x that of steel). Even steel roofs make a noise in hot and cold weather, said Colin. The only way to resolve this is to make sure the screws have expansion allowance (holes must be at least 3mm oversized) and screws are not to be over-tightened with an expandable (PE or PU type) closure. Coetzee has now retired from the industry and moved to Robertson in the Western Cape. 58

the frame, while heat deflection at high temperatures protects the frames even when left on a car dashboard in hot sun. In addition to its intrinsic light weight of up to 50% vs. metal, Ultem resin is suitable for precision thin-wall moulding down to 1.2 mm, cutting weight even more. The weight of the Zoff SMART frame is 9.4 g without the lens, which compares very favourably to metal frames typically weighing around 20 g. The material can be custom coloured to provide a wide range of aesthetic effects.

Cushion the impact! Spring element made of low-emission resin acts as buffer during steering column adjustment BUFFER-stops made of the low-emission grade DuPont™ Delrin® 100PE acetal resin cushion the impact when mechanically-adjustable steering columns, from ThyssenKrupp Presta of Eschen, Liechtenstein, reach full horizontal adjustment. Decisive factors in its specification were the material’s compliance with stringent emission levels demanded by some of Germany’s automotive OEMs for interior applications and its steel-like springiness. The material is also characterized by its vibration damping effect, its high notched impact strength and very good sliding properties. The buffer-stop, injection-moulded in Delrin 100PE, takes up very little installation space with its 14 mm x 9 mm x 6 mm dimensions. Held by a rivet, it slides during adjustment of the steering column on metal guide rails until they reach their limit at the end of the adjustment range. Although the associated jolt may in some cases be hard, two small springs on either side of the buffer-stop are enough – thanks to the high stiffness and elasticity of the ma-

Testing by the SGS Institut Fresenius GmbH in Germany, in accordance with the VDA standard 275, confirms that all three low-emission grades of Delrin® meet the demanding emission requirements of the world’s major automotive manufacturers. (PHOTO: DUPONT)

terial – to cushion the impact both mechanically and acoustically. As a direct benefit of the excellent sliding properties of Delrin acetal resin, the buffer-stop will continue to move easily, softly and virtually inaudibly on the guide rails for the entire lifetime of the vehicle. These high-precision parts that are characterized by their variable wall thicknesses, are produced in 16-cavity hot runner moulds and kept within a tolerance of just ±0.05mm. The combination of high elasticity and stiffness as well as excellent sliding properties make Delrin acetal homopolymers a material of choice for applications requiring low weight and where elements are required to absorb high forces, levels of deformation and impact, as well as to continuously move both smoothly and quietly. www.dupont.com

A plastic that remembers Shape memory polymer developed from thermoplastic polyurethane A NEW thermoplastic polyurethane (TPU) developed by Bayer MaterialScience together with the BAM Federal Institute for Materials Research and Testing in Berlin, Germany, shows that plastics can also have a memory. Parts made of such a plastic can be temporarily reshaped and fixed in this shape. When heated to a certain temperature known as the switching temperature, they ‘remember’ their original shape and return to it virtually unchanged. In the case of the new product Desmopan® DP 2795A SMP, the switching temperature is approximately 40°C. The abbreviation SMP stands for the English designation for such plastics: Shape Memory Plastics. “Given this special property, there are virtually no limits to the potential applications for the plastic,” said Jürgen Hättig, head of Business Development for TPU at Bayer MaterialScience. “We can imagine applications in areas ranging from mechanical engineering and the automotive, textile, sports and leisure industries to toy manufacturing and aerospace engineering.” Possible applications include the easy repair of damaged bodywork parts using a hair dryer, remote temperature sensors, artificial muscles, hinges, self-loosening screws, packaging and shrink tubing.

Self-erecting film tunnels & counterfeit-proof labels The two partners recently submitted a patent application for a possible application in the area of functional film tunnels and self-erecting structures. Film tunnels in a field act like greenhouses and accelerate the growth of lettuces and vegetables so that these can be harvested sooner than is possible if allowed to mature in the classic manner under the open sky. This is an opportunity for the new shape memory polymer. Profiles made of the new TPU plastic that have temporarily been brought into a flat shape are fastened to the transparent film. After the film has been laid on the bed, all that’s left to do is to heat the profiles to the switching temperature. They ‘remember’ their bent, permanent shape and pop up to form a half-tunnel, lifting the films with them. The new material could also prove useful in product and brand protection applications. BAM has used the TPU product to develop labels with engraved and coloured quick response (QR) codes. The codes can only be read if the labels are in their

The new material could prove useful e.g. in product and brand protection applications. The BAM has used the TPU product to develop labels with engraved and coloured quick response (QR) codes. The codes can only be read if the labels are in their permanent shape. The labels are thus very well suited as a means of storing information to mark and identify products in a way that is very difficult to counterfeit

permanent shape. Because the TPU material is free from plasticizers and antihydrolysis agents, it is also suitable for food contact applications. It also boasts all the typical advantages of TPU, such as high abrasion resistance, flexibility and good chemical resistance. www.materialscience.bayer.com

TPV medical elastomers Low compression set in rubber-replacement applications like stoppers, seals and gaskets A SERIES of thermoplastic vulcanizate (TPV) elastomers spanning a wide range of hardness levels exhibits high purity and resilience for replacing rubber in medical applications and provides performance and processing advantages over other thermoplastic elastomers (TPEs). Medalist® MD-200 Series elastomers range from ultra-soft 15 Shore A compounds to 80 Shore A grades, avoid the need for pre-drying because they are nonhygroscopic and have a light natural colour that allows efficient use of colorants. The compounds contain none of the extractable heavy metals commonly used in the curing of thermoset rubber. Because they exhibit lower oxygen absorption than non-vulcanizate TPEs, they give greater protection www.medalistmd.com

to pharmaceutical contents when used in seals or gaskets for vials. Medalist MD-200 compounds show greater resilience than other TPEs, perform well in high-temperature end uses and are more chemical-resistant. Most grades in the series adhere well to polypropylene in over-moulding. Used commercially as a replacement for thermoset rubber in syringe stoppers, Medalist MD-200 compounds meet the requirements of ISO 7886 for single-use hypodermic syringes and exhibit a low coefficient of friction for consistent travel force in glass and polypropylene barrels. • ADVANCED POLYMERS REPRESENTS TEKNOR IN SOUTHERN AFRICA

Power Factor Correction:

TECHNICAL

Reduce your electricity costs and free up capacity Power factor correction can save electrical energy costs and free up electricity supply capacity BY ERIC SOLOT: ALPHA POWER SOLUTIONS CC JOHANNESBURG

Power factor correction of inductive loads An inductive load, such as a motor, draws current from the supply, which is made up of resistive components and inductive components. The resistive components are: Loss current (small); Load current The inductive components are: Leakage reactance current (small); Magnetizing current 3

Up until fairly recently, the return on investment for power factor correction equipment in commercial and industrial applications was unacceptably long for most company. Avoidance of wasteful electricity demand and consumption was in the past not given the attention it deserves and energy efficiency has only very recently become a strategic objective for most companies. The significant electricity tariff increases introduced in recent years have made investments in power factor correction very attractive for most commercial and industrial consumers. 1

What is power factor? Power factor (also referred to as cosine phi) is the ratio between the active load power (KW) and the apparent load power (KVA) drawn by an electrical installation. It is a measure of how effectively the current drawn by the load is being converted into useful work output.

All current will cause losses in supply and distribution systems. A load with a power factor of 1.0 results in the most efficient loading of the supply and a load with a power factor of 0.5 will result in much higher losses in the supply system. A poor power factor can be the result of a significant phase difference between the voltage and current at the load terminals. Poor load current phase angle is generally the result of an inductive load such as an induction motor, power transformer, lighting ballasts, welder or induction furnace. A poor power factor due to an inductive load can be improved by the addition of power factor correction. A poor power factor can also be caused by a high harmonic content or distorted/discontinuous current waveform. A distorted current waveform can be the result of a rectifier, variable speed drive, switched mode power supply, discharge lighting or other electronic load. The power factor of a load with a distorted current waveform requires a change in equipment design or expensive harmonic filters to gain an appreciable improvement.

Figure 3 – Current vectors

The current due to the leakage reactance is dependent on the total current drawn by the motor, but the magnetizing current is independent of the load on the motor. The magnetizing current will typically be between 20% and 60% of the rated full load current of the motor. The magnetizing current is the current that establishes the flux in the iron and is very necessary if the motor is going to operate. The magnetizing current does not actually contribute to the actual work output of the motor. It is the catalyst that allows the motor to work properly. The magnetizing current and the leakage reactance can be considered passenger components of current that will not affect the power drawn by the motor, but will contribute to the power dissipated in the supply and distribution system. In the interest of reducing the losses in the distribution system, power factor correction is added to neutralize a portion of the magnetizing current of the motor. Typically, the corrected power factor will be above 0.95. Some municipalities penalize consumers with a poor power factor by charging them for excessive kvarh consumed (>30% of kWh consumed during the same period) and by doing so encourage them to reduce wasted energy by applying power factor correction. Power factor correction is achieved by the addition of capacitors in parallel with the connected motor circuits and can be applied at the motor (static power factor correction) or at the distribution panel (bulk power factor correction). The resulting capacitive current is a leading current and is used to cancel the lagging inductive current flowing from the supply to the inductive load. Magnetising Current

Bulk power factor correction When bulk power factor correction is applied, the power factor of the total current supplied to the distribution board is monitored by a controller which then automatically switches capacitor banks in a fashion to maintain a power factor better than a pre-set limit (typically between 0.95 and 0.98). 3.1

Figure 5 – Bulk power factor correction

Ideally, the power factor should be as close to unity as possible. There is no problem with general correction operating at unity (even though this is usually not the most cost effective target power factor), but correction should not be applied to an unloaded or lightly loaded transformer. If correction is applied to an unloaded transformer, you create a high ‘Q’ resonant circuit between the leakage reactance of the transformer and the capacitors and destructive high voltages can result. Static power factor correction As a large proportion of the inductive or lagging current on the supply is due to the magnetizing current of induction motors, it is easy to correct each individual motor by connecting the correction capacitors to the motor starters.

With static correction, it is important that the capacitive current is less than the inductive magnetizing current of the induction motor. In many installations employing static power factor correction, the correction capacitors are connected directly in parallel with the motor windings. When the motor is Off Line, the capacitors are also Off Line. When the motor is connected to the supply, the capacitors are also connected providing correction at all times that the motor is connected to the supply. This removes the requirement for any expensive power factor monitoring and control equipment.

New CVe monitor for tracking mould activity Mould management device provides useful insights into mould’s performance PROGRESSIVE Components, a leading global supplier of mould components for production tooling, has introduced an electronic mould monitoring device called the CVe Monitor™. This mould management device monitors more than just mould cycles completed. It gathers specific data which can either be viewed by toggling through the mould monitor’s onboard display screen or by downloading the information by connecting the monitor to a PC via the monitor’s miniUSB port. The following data is shown on the display and can be toggled by pressing a button on the CVe: total cycles cycle time: life of the tool cycle time: past 25 000 cycles activity percentage: life of the tool activity percentage: past 25 000 cycles The monitor includes a resettable cycle count meter that can be used for short run verification of cycles versus parts manufactured.

downloaded. This allows various reports to be generated which provide useful insights into the mould’s performance. To access this facility, the ‘On-Demand’ software needs to be downloaded. This software is provided free of charge with the purchase of each monitor. The software’s reporting capabilities mean that users can generate and save reports locally or on a network. Users also have the option to send emails to management, customers or OEM’s when the reports are run. The reports are saved in both encrypted Excel and PDF formats. The reports use data from the CVe to provide weekly views of the mould’s performance, including the cycle times, up and down times for the life of the tool and the last 25 000 cycles. An important feature is that mould drawings, along with any other relevant documents, can be stored on the monitor’s 2 GB internal flash drive. This means that wherever in the world the mould is, there is a complete record of its history, as well as making all technical drawings easily accessible to whoever may need them. Confidentiality is protected by means of

a password control feature. This is of immense benefit to OEM’s who use different moulders to produce their goods. To facilitate ‘retro-fitting’ the CVe requires the same pocket size as the popular parting line mechanical CVPL CounterViews and it has a battery life of 50 000 hours (5 years). The software works with Windows XP or Windows 7 platforms and can be installed on any computer in the plant. The user of the software needs to register and will receive a username and password to run the software throughout the company. • View the new YouTube video at: www.youtube.com/watch?v=n5_ 9icvkLaE&feature=plcp

The core of the capsule, the polypropylene and TPE coffee holder, is injected on an Engel victory 1350H/200W/220 combi machine in a 32+32x rotary plate mould. The key to reducing cycle times is cooling the hard component. To accelerate this process, in-house mould making replaced

the cooling water supply hoses with thicker pipes. They jut out upward through the mould area and are directly connected to the cooling unit. Because there are no tiebars in the way, the pipes can easily follow the motion of the rotary plate.

The Engel victory 1050H/330W/ 200V/400 combi is used to produce housings for electric manual tools by Anton’s largest customer, Bosch. After an Engel viper 20 linear robot has insert-placed the metal inserts into the 2+2x rotary plate mould, the left and right housing shells are first injected from green PP GF30. Following this, the mould rotates to a second position where the three following components are applied in a single step using corepulls:

first the red Bosch label (PP GF30), then black, and finally grey TPE S on the handle surfaces.

The system is designed for machining screws with diameters ranging between 43 and 184 mm. Counter-rotating twin-screw extruders transport the material almost completely in the axial direction in an enclosed chamber system. The speed and pressure conditions caused by the system result in a so-called

calendar effect with flow conditions in the comb-out area of the screws. In both the solids and melt handling areas, this calendar flow under high surface pressures leads to adhesive wear effects resulting from the screw shafts being pushed apart, and the screw shafts can only support themselves on the barrel. As a result of this abrasive wear mechanism, permanent damage can be caused during manufacturing to screws and barrels, which can sometimes lead to a complete failure of the system. Optimized welding process parameters such as the current in relation to the screw outer diameter and the customized composition of the flux powder ensure the production of PTA-molybdenum hard facing that is practically free of cracks with the lowest possible dilution especially in the outer areas of the weld. KraussMaffei Berstorff also offers a PTAproduced high-wearing surface coating for all parallel twin-screw extruders with tungsten-carbide reinforcement. Tungstencarbide coatings are used for heavy adhe-

sive wear, for example for the processing of natural fibre composites for decking profiles. As a result, the KraussMaffei Berstorff twin-screw extruders for WPC processing achieve much higher service times compared with standard machines which, depending on the formulation and correct operation of the machines, can add between 12 000 and 20 000 operating hours. • PLASTIC & CHEMICAL TRADING CC ARE THE SA AGENTS, TEL: 011 483 3015 www.kraussmaffeiberstorff.com

Robot wins global prestige award Makes it possible for small and medium-sized companies to automate production THE Danish robot arm UR5 from Universal Robots recently won an international robot competition at the largest global automation exhibition ‘Automatica’ in Germany. Hundreds of companies in Europe and Asia use the innovative robot from Universal Robots to automate their production. In a cutthroat competition with robots from Japan, USA, Germany and England, the UR5 robot from Danish Universal Robots has now been elected as the world’s most innovative robot. The award is also recognition of the record growth that the company behind the new flexible robot arm has obtained since 2008. An expert jury from the two international

robot organizations, The International Federation of Robotics (IFR) and IEEE Robotics and Automation Society, paid tribute to inventor, Esben Østergaard, by handing him a statuette for Invention and Entrepreneurship in Robotics and Automation Award. The UR5 is safe, user-friendly and flexible because it can work side by side with employees, increasing efficiency. The jury did, however, also stress the fact that Universal Robots has made it possible for small and medium-sized companies to automate production, because the UR robots are both reasonable in price and easy to implement in production.

Global breakthrough In 2011, Universal Robots really had their breakthrough when the company sold 400 robots globally. This year, the robot producer expects to at least double sales. The name of the company behind the innovative robot in itself explains why the robots are so popular. The robots are universal in the sense that everybody is able to use them all over the world and for all kinds of automation tasks, and that is exactly what one of the inventors, Esben Østergaard, set out to do. • UNIVERSAL ROBOTS IS REPRESENTED BY PLASQUIP IN SOUTH AFRICA.

Crystallization of PET masterbatches IR Batch, more than just a perfect crystallizer AT NPE 2012, Kreyenborg Plant Technology of Germany displayed its latest addition to their IRD technology, the IR Batch, which uses very efficient shortwave infrared radiation instead of hot air as a heat source.

Thus, conventional, agitated mixing crystallizers were not reliable, as the start-up of such systems with amorphous material is a definite challenge. These conventional systems were originally built for semicontinuous silo-type ‘FiFo’ principal working crystallizing jobs in the injection moulding industry. In these semi-continuous processes, the start-up of the system is not an issue, as For several years now, Infrared-Drum Dryers have proven themselves as superior crystallized material for the start-up process is usually available. technology in many PET applications.

Example of a continuous working IRD with 2 temperature zones

heating process in this part of the processing window. A small IRD-A type for small throughputs offer little options to adjust the process according to various MB types. It offers only one temperature zone and a limited drum rotation speed adjustment. Even larger machines of an IRD-B type offer a maximum of three different temperature zones for running a temperature profile but only a small process window for the drum rotation speed as well. Therefore, the amount of mechanical mixing energy cannot be varied through the length of the drum. Materials which are difficult to heat up can really challenge the processing limits of such continuous IRDs. Such difficult materials may include specific colours and/or PET copolymer types for special applications. The IRD may not offer enough residence time or mechanical mixing energy to produce perfectly crystallized granules, for example ‘twins’ of granules which were melted together can exist.

Processing sequence of the IR Batch System


Challenging applications no problem These really challenging applications can be perfectly crystallized in the IR Batch. As opposed to the continuous working IRD types, the IR Batch operates in a discontinuous or batch principle. A defined batch size is fed into the drum and then heated up by a preset temperature profile to the crystallization temperature while the drum is rotating. After finishing the crystallization, the material is discharged by a counter-rotational movement of the drum. Once emptied, the machine is ready for the next crystallization cycle and can be fed with new material again. The discontinuous process has some important advantages for materials which are difficult to crystallize. As it is not directly linked to an inline process, the drum rotational speed can be increased as high as possible to achieve an excellent mixing of the pellets during the critical crystallization phase. The typical sequence is a fast heating of the PET Masterbatch in the beginning. Therefore the drum rotation is relatively slow and the IR radiator power of the system is higher. Once the material gets to the critical crystallization temperature of between

104°C and 135°C, the speed of the drum is increased to a much higher rotational speed to avoid any clumping of the material and assure a very good cross mixing of the material. After the material is through this critical section, the radiator power or heat can be increased again to finish the crystallization process, meanwhile the drum rotation can be slowed down again. Typically this crystallization process is finished after 15 – 20 min, depending on the material. After finishing the process, the IR Batch will automatically discharge the drum and begin the sequence again by refilling the drum. A pneumatic slide gate will open the dosing hopper and new material will be loaded into the drum. While the crystallization/heating process starts again, the machine will meanwhile refill the dosing hopper for the next cycle. With the operation of the IR Batch running automatically and in a closed loop, the throughput rate (i.e. for 14kg/15min) will result in a total average throughput of 54kg/hr. The automatic refilling as well as all relevant parameters for the different temperature ramps is fully integrated in the state-of-the-art Touch Screen control. Once parameters and temperature profiles are

found for a specific material, theses settings can be saved as recipes in the control system. A common side-effect of highly-filled masterbatches is the electrostatic loading of the pellets. In order to avoid sticking from electrostatic effects, Kreyenborg Plant Technology developed a special Masterbatch Package for the IR Batch which includes an ionization unit to neutralize electrostatic loadings within the material. Besides the critical behaviour of highlyfilled or modified PET masterbatches, the cleaning of processing equipment can be one of the most important and time consuming details. The IR Batch can be opened completely, and the Infrared module slides out on a separate frame. The drum with the simple mixing elements has no hidden spots and can be cleaned easily with a vacuum cleaner or compressed air. This enables the operator to have a very quick change from one material to another. www.kreyenborg.de

No compromise! Optimal contact between rollers and film yields improved transparency WITH its new Multi-Touch polishing stack, battenfeld-cincinnati, Bad Oeynhausen/ Vienna, has developed an optimal solution for film producers who are not prepared to compromise on film quality even at high line speeds. Thanks to an absolutely innovative concept, a high degree of transparency, excellent flatness and an extremely even film thickness can now be achieved for a great variety of materials, such as PS, PET or PP, as well as EVA or laminated products. As is the case in all sectors of the extrusion industry, outstanding efficiency in the production process is also a must in film extrusion today. The demand is for higher and higher output with optimized product quality. Criteria such as transparency, high gloss and flat-ness are vital factors especially in the production of packaging sheet for thermoformed products. At the same time, film and sheet producers want to be able to respond as flexibly as possible to the diversity of incoming orders. The main idea in the design of this new polishing stack was derived from the assumption that infinite line speeds could be realized with an infinite number of gaps for final calibration. In the Multi-Touch polishing stack, this idea has been put into practice with a two-roll polishing stack for preliminary calibration, followed by three,

five or seven rolls for final calibration. The first two rolls come with a large diameter to minimize deflection. They are followed by smaller rolls to achieve flat, stress-free film and sheet. In contrast to the well-established, conventional threeroll polishing stacks, the Multi-Touch polishing stack provides absolutely even, consistent contact between the film and the rolls even at maximum line speeds, which ensures optimal cooling of both sides of the film. The greater number of post-cooling gaps provides a reliable means to even out film thickness tolerances. In this way, film can be produced with maximum transparency, excellent flatness with only few orientations, and a uniform thickness profile. Thin-walled chill rolls with small roll diameters are used to facilitate easy handling, with a simultaneous increase in cooling performance. They offer the same hardness and line load capacity as conventional rolls, yet operate significantly more efficiently. The first Multi-Touch polishing stack has been up and running on the production floor of a major German film producer since autumn 2011. The polishing stack is now available with up to 7 post-cooling chill rolls for outputs of up to 3 600 kg/h for PP.

Krones’ SuperClean-PET-flake process is able to produce flakes at a high degree of purity, which can be directly used for making new bottles

Closed-circuit recycling From container feed right through to finished, decontaminated flakes from a single source FOOD company Stute Nahrungsmittelwerke in Paderborn, Germany, is rigorously pursuing its eco-friendly strategic thrust. After investing in three wind farms, a biogas system and several solar power installations that together cover more than 30% of Stute’s own energy requirements, this privately owned company will in future also be able to completely recycle PET material. The beverage plant will commission Germany’s first PET recycling line from Krones in August. The SuperClean-PETflake process is able to produce flakes at a high degree of purity, which can be directly used for making new bottles. Conventional processes, by contrast, require additional steps for creating food-grade recyclate. Stute plans to feed back both PET bottles and preforms into its bottle production operation. This also includes bottles that have already come into contact with product. The recycling process washes and decontaminates the rejected PET,

guaranteeing its suitability for future foodgrade applications. From the recycling line directly into the injection-moulding machine The PET materials waiting to be recycled are first comminuted and then fed to the washing system’s storage silo. The PET recycling line is made up of the following main components: washing module, decontamination module, plus the peripherals. The line is installed on two different levels: the washing module and the decontamination module are spatially separated, with the latter located directly next to the existing injection-moulding machines for producing preforms. The decision in favour of Krones was an easy one for Stute, since Krones is the only manufacturer able to offer a complete system, from container feed right through to the finished, decontaminated flakes from a single source, thus reliably eliminating any interfacing problems.

In response to market trends, Stute is shifting its container priorities, progressively away from carton packaging and towards PET containers. Stute has meanwhile been operating 13 PET lines in its Paderborn facility. Since 2009 Stute has rigorously opted for Krones’ technology when it comes to new investments. To start with, there was its first PET-Asept variant, which was followed by two lines with a Contipure preform decontamination feature. Thanks to the innovative preform decontamination feature, consumption figures for both energy and media have been significantly reduced as compared to container treatment. In mid-2012, what will then be the firm’s fourth Krones line will start operation – this one, too, a PET-Asept line. There are plans for further investments with Krones to replace some relatively old lines.

Intelligent control THE new Illig Intelligent Control Concept was a main feature at Illig’sOpen House hosted at Heilbronn in May where more than 200 guests had the opportunity to gain insight into technology and performance of current Illig automatic roll-fed machines. The Illig Intelligent Control Concept (Illig IC) is a modular design allowing the user to make optimum use of the various possibilities. The compatible modules are geared at improving productivity and reproducibility, as well as the availability of a thermoformer and/or a complete thermoforming line. Using the TermoLineControl module, all machine components of the production line can be called up and programmed centrally on the touch panel at the forming station. At the same time various auxiliary functions are available for process optimization and reduction of tool installation times. To improve process reliability, a compensation control balances the effects of changing environmental influences during ongoing production. Using the new sas-up® (self-adaptive start-up) module results in a considerable reduction in material consumption during start up and commissioning of new tools. The Illig Intelligent Control Concept (ILLIG IC) is rounded off by interlinking a production line with the NetService. In this way service engineers from Heilbronn can look into all line components via internet, diagnose errors and correct setting-related malfunctions rapidly.

Participants at the Illig open house show were especially interested in the demonstration of the new Intelligent Control Concept which allows utilization of the entire potential of today’s servo-driven thermoformers to the full extent

First truck charge-air duct in Ultramid A PLASTIC compound from BASF has, for the first time, found use in the chargeair section of a commercial vehicle. The charge-air duct on the DD13®/DD15® truck engines is one of the first large production applications for the new polyamide (PA) grade Ultramid® A3W2G6. The multifunctional oil intake module is also manufactured from a BASF polyamide. The designation DD13/DD15 covers a range of high-performance truck diesel engines with a displacement of about 13 and 15 litres, respectively. Compared to its aluminium predecessor, the lightweight charge-air duct made from the BASF polyamide is 1.8 kg, or 50 %, lighter. The high heat-aging resistance of the polyamide 66 specialty Ultramid A3W2G6 is confirmed by its performance in pulsating pressure tests of the component at 140°C. The charge-air duct must survive 3 000 hours of pressure fluctuations between 0.4 and 3.5 bar. The oil intake module on the DD13/ DD15 is made from Ultramid® A3WG7 and, in addition to the oil intake connection and oil supply line, incorporates an integrated check valve.

Trelleborg’s seals are required to protect the bearing from seawater and resulting corrosion and wear to the metal parts, while allowing the smooth rotation of the hook shaft.

The Turcon Roto Glyd Ring is a seal made of Trelleborg’s proprietary PTFE (polytetrafluoroethylene) based material. The characteristics of PTFE have won it wide use in industrial applications, especially in environments where movement is involved. It has a low friction coefficient and

is stick-slip-free, thus allowing smooth transition from a stationary state to movement. In addition, it is a long-lasting material that displays excellent chemical resistance and fluid compatibility.

As pressure from liquids such as seawater or oil increases, the pressure with which the O-Ring pushes the PTFE seal onto the counter surface also increases, thus ensuring that the seal remains tight

Laser transparency for engine cooling THE new Ultradur® LUX is being used in an air flap control unit, an unusual serial application in automotive construction. Motor developer Precision Motors Deutsche Minebea (PM DM), based in Villingen-Schwenningen, Germany, is using this highly laser-transparent and easily laser-weldable BASF plastic from the PBT family to make the housing cover of its novel control module. This small actuator consisting of gears, an electric motor and an electronic unit serves to control the air flaps in motor vehicles, thus contributing to better aerodynamics and lower CO2 emissions. The highly lasertransparent PBT Ultradur LUX accounts for stiffness and dimensional stability, even in damp environments. The product’s key characteristic is its high transparency toward near-infrared light in the 800 to 1100 nm wavelength, precisely the crucial range for penetration laser welding. The improved transparency to laser light means that this material can be welded faster than other PBT grades available on the market. The processing window is considerably wider and the risk of damage to the material is much lower. The grade used here, Ultradur LUX B4300 G4, is reinforced with 20% glass fibres.

SACMI, SIPA collaborate in preform closure project Features special combination of preform neck finish and lightweighted caps SIPA (Zoppas Industries Group) and Sacmi, two of Italy’s most innovative companies operating in the packaging sector, have combined their skills in the search for a new solution in the combination of PET preforms and closures that provides advantages for processors and end-users alike. The collaboration, which has been given strong backing from the two companies’ managements, headed by Enrico Gribaudo (SIPA) and Giuseppe Lesce (Sacmi) respectively, combines SIPA’s substantial experience in the development of preforms, with that of Sacmi in caps and closures. A combined development team incorporates a level of technical competence considered unrivalled anywhere in the world. The fruit of this collaboration is a new solution – with the acronym S.U.P.E.R. – featuring a special combination of preform neck finish and lightweighted caps that solves several key problems associated with the operation of a cap on the neck of a PET bottle, with results previously not thought possible. S.U.P.E.R. stands for Sustainable, Unique, Productive, Easy, and Reliable – the five key benefits of this innovative solution: Sustainable, because the closure will be lighter than the average of alternatives on the market today, reducing the processor’s consumption of raw materials and energy; Unique, because this is a proprietary solution, protected by patents, that will provide benefits exclusive to those who adopt it; Productive, because it reduces the time and cost of equipping production lines – when switching between containers for various types of products, including water, soft drinks, and aseptically filled drinks, very little modification is required to lines for either preforms or closures (the latter produced with SACMI’s compression process, which already offers reduced tooling times and high production speed); Easy, because the solution provides the consumer with a bottle that is easy to open. The guaranteed positive LB angle – the leak angle is greater than the bridgebreak angle, a feature not available on the market today with current closure solutions – gives the perception of a closure that is very easy to open; Reliable, because the special tamper evidence system provides an immediate breakage of the security strip, rendering the bottle secure, with no risk of blow-off. www.sacmi.com

SABIC’s Qrystal high-clarity PPs save time, energy Designed with unique flow behaviour to produce parts faster, lower energy consumption TO MEET the need of converters for materials that deliver better finished products and that can be produced cost-effectively, SABIC has developed two new high clarity SABIC® PP Qrystal polypropylenes. These random copolymers, typically for injection moulding, were specially designed with unique flow behaviour, providing processors with the flexibility to produce parts faster and with lower energy consumption. SABIC PP QR674K, with a melt flow rate (MFR) of 40g/10min, was typically developed for more sensitive food contact applications, owing to its improved organoleptic performance (low odour). Typical target applications are caps and closures, houseware, kitchenware and food/nonfood containers. SABIC PP QR678K, with its high MFR

of 80 g/10 min, is better suited to production of parts with complex shapes and/ or long and narrow flow paths. Customer trials have shown around 15% higher flow than a standard PP random at the same MFR level, allowing machines to run at lower processing temperatures and 15% faster cycle times, potentially decreasing production costs. SABIC has a broad package of PP random copolymers that provide solutions for a wide range of applications, providing a combination of good transparency with lower conversion costs. The SABIC PP Qrystal range, which was launched in 2010, now comprises four grades, with MFRs ranging from 25 to 80 g/10 min. All SABIC PP Qrystal grades can be processed at much lower temperatures than many other commonly used copolymer polypropylenes from the market, leading to significant reductions in cycle time and energy consumption, as a sustainable solution to decrease the moulded article carbon footprint. They also have a good balance of impact strength and stiffness and enable customers to produce parts with no loss of transparency or aesthetics. The SABIC PP Qrystal grade family is produced both in Europe and the Middle East and can be delivered globally. www.sabic.com SABIC’s Qrystal® polypropylene grades achieve new levels of optical performance ... as well as energy savings for converters

‘Drop-in’ solution for PA12 extruded, injected components TECHNYL eXten alternative to PA12 with grades for tubing, flexible hoses, injection moulded parts TO bring high-performance, economical solutions to the automotive and the manufacturing industry quickly in the midst of the PA12 crisis, Rhodia Engineering Plastics, member of the Solvay Group, is proposing its Technyl® eXten PA6.10 product as a drop-in solution for a variety of applications where PA12 is typically used. Rhodia’s application experience to date, developed in partnership with its customers since 2010, show that Technyl eXten PA6.10 is a versatile alternative to long chain polyamides such as PA12. For many existing PA12 applications, Rhodia brings a true drop-in solution that will do the job. That’s more important than ever as PA12 supplies continue to tighten. “Compared with PA12, Technyl eXten grades offer customers a range of technical and cost-benefit advantages, in addi-

tion to their environmental performance,” said Pierre-Emmanuel Lucas, new business project director for Rhodia Engineering Plastics. “Working closely with our customers, we have the ability to provide a quick solution for many different applications where PA12 is now used, and where supplies of that material are in jeopardy going forward,” he added. Introduced to the market in 2010, Technyl eXten grades are available for both extrusion and injection moulding and are specifically suited to the manufacture of flexible tubes for the transportation and industrial industry, and glass reinforced moulded parts such as fittings and adapt-

ers for the engine fuel systems market. In addition, it is partially based on raw materials from natural origin and shows an improved environmental profile.

Glow-in-the-dark masterbatch saves lives! Allows emergency medical personnel quick access to treat wounds WHEN the inventors of the Rip Shears* Ripper received feedback from medics in the field that their life-saving product would be even more effective if it glowed in the dark, they and co-developer ICON Injection Moulding (based in Phoenix, Arizona, USA), sought assistance from custom compounder RTP Company because of their expertise with visual effects. Attached to a standard pair of trauma shears, the Rip Shears Ripper allows emergency medical personnel to quickly slice through multiple layers of clothing,

equipment and body armour to access and treat wound sites. While medics loved the snip and rip performance of the product, a glow-in-the-dark version would allow even faster usage at night or in low light conditions. “This was a very specific request; we hadn’t done a glow-in-the-dark product before,” explained Steve Kleitsch, ICON’s co-owner. “But, we were aware of RTP Company’s expertise with visual effects, so we brought them in for assistance.” The Rip Shears Ripper uses an RTP

200 Series glass fibre reinforced nylon 6/6 compound. It provides the stiffness needed to allow the blade to stay on track and flow through fabric cleanly. If the plastic were to flex, even slightly, bunching of the fabric could slow down the ripping process. For the glow-in-the-dark version, called the Rip Shears Firefly, RTP Company supplied a phosphorescent glow-in-the-dark colour masterbatch that combines with the reinforced nylon compound during moulding. Advanced glow-in-the-dark technology imbues the material with an ‘afterglow’ effect that lasts for up to 8 hours, which is about 10 times longer than traditional GITD technologies. “RTP Company got the glow-in-thedark effect and product performance right on the first try, right out of the gate,” said Kleitsch. “The inventor loved it and we began production immediately.” www.rtpcompany.com www.iconinjectionmolding.com The Rip Shears Firefly – RTP Company supplied a phosphorescent glow-in-the-dark colour masterbatch that combines with the reinforced nylon compound during moulding 92

Tough PVC elastomers for electric vehicle charger cable Cost-effective alternatives for insulation and jacketing TWO Flexalloy® PVC elastomer compounds from Teknor Apex Company provide manufacturers of charger cable for electric vehicles (EVs) with cost-effective alternatives in terms of both insulation and jacketing. The new compounds are Flexalloy 89504-90, a 90 Shore A formulation for insulation, and Flexalloy 9610-78 for jacketing, with Shore A hardness of 78. The materials exhibit brittle points of -46 and -38ºC, respectively, and are both rated for a maximum continuous operating temperature of 105ºC (typical physical, electrical and flame properties appear in the accompanying table). Unlike standard flexible vinyl, Flexalloy compounds are based on ultra-high molecular weight PVC resin. They exhibit improved toughness, abrasion resistance and low temperature properties and pro-

vide elastomeric resilience and resistance to compression set, according to Mike Patel, wire and cable industry manager for the Vinyl Division of Teknor Apex in the USA. The compounds can be processed on standard PVC equipment. “Teknor Apex developed these two new Flexalloy products especially to meet the requirements of UL Type EVE for the high production volumes and rugged end use performance posed by EV charger cable,” said Patel. “They provide cost-effective alternatives to premium-priced elastomers such as TPUs.” • THESE TEKNOR APEX MATERIALS ARE SUPPLIED IN SOUTH AFRICA BY ADVANCED POLYMERS. www.teknorapex.com

Resealable closure for infusion bags New application of medical compounds from KRAIBURG TPE COMPOUNDS from the Thermolast® M product range of the German TPE specialist Kraiburg TPE will soon be used in medical products made in Bolivia: Matriplast S.A. based in La Paz will use this advanced product to manufacture high-quality infusion bag closures for the South American market. Matriplast produces closures for infu-

sion bags that are made from the special medical series Thermolast M. These materials are certified for medical applications in most countries. In addition, they can be processed very efficiently and hygienically. The TPEs can be sterilised in hot steam up to 135°C and are available in hardness grades between 35 and 45 Shore A. They also have resealing properties which makes them ideal for use in infusion bags: As the TPE diaphragm is extremely elastic, it immediately seals the septum when the infusion line is removed from the bag.

AUGUST / SEPTEMBER 2012

When push comes to shove In contrast to a conventional septum made in rubber, TPE has the added advantage that it can be processed by two-component injection moulding bonded with PE and PP. There is thus no need for the manual assembly of the rubber bag closures, so time and money can be saved while the risk of non-conforming bags is minimised. The new solution also does away with costly storage of the closure components and contamination of the septum is simply impossible. While rubber components always pose a risk of contamination with potentially hazardous substances produced in the chemical reaction, such contamination cannot occur with thermoplastic elastomers, as they are not cross-linked.

Borealis coating protects Nord Stream gas pipeline

BOREALIS, a leading provider of chemical and innovative plastics solutions, is extending the high-level protection benefits of its Borcoat™ steel pipe coatings to Europe’s longest offshore natural gas steel pipeline, Nord Stream. The advanced performance

offered by Borcoat will help secure the integrity of the pipeline over its minimum 50 year service life. Nord Stream is a steel pipeline project routed under the Baltic Sea, designed to transport natural gas a distance of 1 224km from the Russian city of Vyborg to the European exit point in Lubmin, near Greifswald, Germany. Each pipe string requires approximately 100 000 12-metre long pipe sections. To meet the tough performance criteria, Nord Stream AG selected the Borcoat bimodal, a three layer HDPE system with increased fusion bonded epoxy (FBE) primer thickness. It provides the mechanical strength necessary for pressurisation to 220 bar and to resist external pressures at depths down to 110 metres. The system comprises a first base layer

of fusion bonded epoxy (FBE) coating, then a layer of Borcoat ME0420, a maleic anhydride grafted polyethylene adhesive giving a strong bond to the FBE, followed by Borcoat HE3450, a black bimodal HDPE. A ‘rough coat’ of Borealis’ RM7405, a black PE ground material grade, was applied to the topcoat while still hot. This rough surface enables a stronger bond to the 60-110mm concrete coating to increase the weight of each pipe to around 24 tons and ensure its stability when laid on the seabed. www.borouge.com www.nord-stream.com www.borealisgroup.com

Eurocopter delivers first A350 XWB passenger door EUROCOPTER is producing the carbon fibre composite passenger doors for the Airbus A350 XWB aircraft at its Donauwörth, Germany, facility. The A350 XWB passenger doors are the first for a commercial aircraft to be made entirely of carbon fibre reinforced plastic (CFRP). The development and manufacture of aircraft components is another mainstay of Eurocopter’s activities in Germany, which complements our helicopter production. The A350 XWB’s door systems demonstrate our innovative strength and international competitiveness in the field of carbon fibre technology. Series production is handled at Eurocopter’s Donauwörth site in a new building designed to meet the exacting requirements of automated production methods

High-tech products for green mobility CUSTOMISED polyamides and polyesters for sustainable mobility concepts and colorants for plastics were the focal points of Lanxess’ exhibition at INTERPLASTICA 2012 in Moscow. Lightweight nylon composite sheets that can be used alone or together with metal sheet in plastic or metal composite designs (hybrid technology) could reduce component weight by another 10% compared to aluminium sheet hybrid designs. Lanxess develops together with its partners in the automotive industry new applications for high-tech plastics. Nylon composite sheet hybrid technology is ideal for automotive light weighting. In many cases in terms of cost-benefit aspects it provides an alternative to thermosetting plastics, which are reinforced with continuous carbon fibres. Components that Lanxess considers possible to produce directly using polyamide 6 in nylon composite sheet hybrid technology include lightweight front ends, car seats, seat cross-members, airbag housings and brake pedals.

BOREALIS has launched a unique, high stiffness polypropylene (PP) grade Bormod™ BH381MO to support manufacturers of industrial pails in meeting their increasing sustainability and product quality goals. New heterophasic copolymer Bormod BH381MO uses Borealis Nucleation Technology (BNT) to achieve a one-of-a-kind balance of excellent stiffness, flow and impact. The PP grade has a melt flow rate (MFR) of 35 that behaves like traditional MFR 45 grades. At the same time its stiffness level (tensile modulus) of 1700 MPa is more than 150 MPa higher than standard MFR 30 grades, yet with the same impact performance of softer grades. The higher stiffness performance is maintained in high temperature environments. The combination of characteristics allows for lower processing temperatures and lower injection pressure including the ability to fill more complex parts. It also supports easier de-moulding. This creates a spectrum of productivity and associated environmental related advantages for

New liquid colour technology for polyolefin blow moulding Liquid vehicle technology ideal for monolayer extrusion blow moulding NEW LIQUID vehicle technology (LVT) developed by Clariant Masterbatches appears to eliminate many of the problems that have prevented wider use of liquid colour and additive concentrates in extrusion blow moulding of polyolefins (high and low-density polyethylene and polypropylene). Initial testing in monolayer containers shows that these highly compatible systems allow for higher pigment loadings and lower usage rates, while practically eliminating past challenges related to screw slippage. Improved resin compatibility results in stronger weld lines in the finished container as evidenced by scores in standard burst and compression-loading tests. “Extrusion blow moulders and brand owners in the personal care and household products markets often find liquid masterbatches to be an attractive alternative to solid concentrates,” said Raymond Sloan, head of liquid colour, Clariant Masterbatches North America. “However, until now, use of liquid colour has been limited in blow moulding of polyolefin resins because many liquid based carrier systems (including mineral oil) would not incorporate well

with the resins. It was pigment friendly, but not resin friendly.” The new Clariant masterbatches use a liquid vehicle system that incorporates suspension aids and binders to allow for higher pigment loadings and (in most cases) lower usage rates. Additional components enhance flow and make for dramatically faster colour changes. Benefits include: Improved weld-line strength. Previous carriers had a tendency to rapidly bloom to the surface of extrusion blow moulded containers, interfering with seam rewelding. The new Clariant liquid products appear to actually assist in the formation of a strong seam. Better processing characteristics. The new Clariant liquid colours have a positive effect on material

flow in the extruder. Reduced screw slippage leads to improved mixing and more complete dispersion and less streaking. It also results in processing temperatures as much as 17°C lower and, therefore, less cooling is required. Faster colour changes and greater productivity. The Clariant LVT products tend not to adhere to metal surfaces and, in fact, can act as a cleansing agent, removing deposits left behind by other colorants. Colour changes that might typically take several hours with solid pellet colorants can now be completed in just minutes with the new liquid colours from Clariant. www.clariant.co.za

Moulding future growth MOULD Release agents are essential products in the design and manufacture of any pre-shaped part – whether it be rubber, plastic, thermoplastic or an advanced composite. Mould release agents form a coating on the mould, allowing the part being moulded to be released quickly and easily. Conventional mould release products have no chemical interaction to the mould surface and release by transferring some of the mould release product to the part surface. Additionally it requires frequent re-application, typically after every release. These release agents are referred to as sacrificial mould release agents. Semi-permanent mould release agents differ from conventional www.loctite.co.za

Like a second skin! ImpranilÂŽ coating opens door to innovations in adidas running shoes and sportswear ATHLETES throughout the world spent a great deal of time preparing for this year’s Olympic Games in London. More than just efďŹ cient technique is required for a runner to achieve peak performance; natural motion and a comfortable ďŹ t are also important. The new ‘adipure’ line of training shoes from adidas supports natural running through a rolling motion over the metatarsus and forefoot. The shoes also satisfy runners’ other requirements, thanks not least to the upper material of the shoe, which envelops the foot seamlessly like a second skin. It owes its unique properties to a textile coating based on a polyurethane dispersion from Bayer MaterialScience’s ImpranilÂŽ range. The textile coating is noted in particular for its high resilience. It is vital for the runner that it is applied precisely to the upper material at the points where the foot needs support. There, the coated material braces the foot but also offers it enough freedom to stretch. As a result, it makes a decisive contribution to the runner’s perfect natural running experience.

When it came to designing the coating, the adidas experts drew on the results of measurements obtained with the help of sensors placed on runners’ bare feet. The application of the coating provided the designers with almost unlimited design scope. Furthermore, the process protects the synthetic upper because the shoe is not subjected to any thermal stress during production. ImpranilŽ dispersions are waterborne and completely cosolvent-free. Textile coatings formulated with them retain their excellent properties after machine washing and drying. Stress-strain tests provide impressive proof of their high resilience.

Biogas from spaghetti? Evonik membranes upgrade biogas BIOGAS is an eco-friendly energy source that is becoming increasingly important in today‘s energy supply. But an extensive upgrading and purification process is required before biogas is fed into the natural gas grid. New and highly selective polymer membranes from Evonik convert raw biogas simply and efficiently into highly pure biomethane. This increases yield and conserves valuable resources. According to the Renewables Global Status Report (GSR) 2011, renewable

energies today account for about 16% of global energy consumption; by the year 2050, this figure could rise to more than 50%. Biogas is produced by fermentation of biomass, an organic substance consisting of, for example, plants, liquid manure, or effluent sludge. But in addition to the methane energy source, raw biogas also contains carbon dioxide (CO2) and other trace gases. Because CO2 is not combustible, it lowers the calorific value of the gas and must therefore be separated out.

The common separation methods such as pressurized water scrubbing, pressure swing adsorption, and amine scrubbing have considerable disadvantages: They need comparatively large amounts of energy as well as auxiliary materials and chemicals. Wastes and wastewater are generated that must be treated and disposed of. Further, the biogas after upgrading is usually at low pressure. Before it is fed into a medium-pressure grid, it needs to be compressed to 15-20 bar by, for example, an additional compressor.

Biogas is produced by fermentation of biomass, an organic substance consisting of plants, liquid manure, or effluent sludge.

It looks like a bunch of spaghetti strands or a paintbrush, but is in fact a bundle of highly selective polyimide hollow fibres in Evonik’s new Sepuran membrane module

Conventional upgrading plants are therefore usually cost effective only for raw biogas quantities significantly in excess of 500 standard cubic meters per hour (Nm³/h). This usually makes them unsuitable for decentralized energy supply with a large number of relatively small plants. Evonik Industries has developed a technology for cost- and energy-efficient separation of CO2. What appears at first sight to be a bunch of spaghetti strands or a paint brush is in fact a bundle of highly selective membranes made up of multiple cylindrical polyimide hollow fibres. These are used in the new hollow fibre membrane modules of Sepuran Green. Highly selective membranes Polyimides are high performance polymers with high pressure and temperature resistance. Sepuran relies on a specially optimized form of Evonik‘s proven and tested polyimide family. The membranes have consistently high selectivity and are particularly suitable for separation of CO2 and methane. How does the membrane work? Gas molecules are different sizes and have different solubility in polymers. The biogas to be cleaned is introduced under high pressure at one end of the membrane. The CO2 molecules are smaller than the methane molecules and also

100

AUGUST / SEPTEMBER 2012


more soluble in polymers. As a result, they pass through the micropores of the membrane much faster and are separated from the methane. CO2, water vapour and traces of ammonia and hydrogen sulphide are drawn off at the low-pressure side (from the lateral opening depicted in the diagram), while the methane collects at the other end of the membrane, the high-pressure

side. The methane-rich gas is directly drawn off at the high-pressure side and needs no further compression for feeding into the grid. This saves the costs of an additional compressor. Further, the biomethane produced in this way can be used even by small plants and therefore allows decentralized supply of energy. In a test plant in Neukirchen an der Vöckla (Austria), Evonik‘s experts have

been putting the production modules through their paces since early 2011. Their experience so far is that the new Sepuran Green membrane modules are a robust and simple tool for gas purification. The methane of the raw gas can be cleaned to a purity higher than 99%. www.corporate.evonik.com

Biogas is produced by microbial fermentation of sustainable raw materials like corn, or from effluent sludge or liquid manure. Following separation of various minor components like water vapour, hydrogen sulphide, and particularly CO2, the biogas can then be used in the gas grid, in combined heat and power plants, and at filling stations

WORLD NEWS

Car part weights could be cut in half LEADING automotive plastics component supplier, Monaco-based Mecaplast, believes it can cut the weight of interior and exterior trim parts by between 30 and 50% by using a newly patented injection moulding processing technology in combination with novel polypropylene compounds. Mecaplast has numerous production facilities across France as well as in Europe, Turkey, Brazil, Mexico, China and India, is about to embark on a French governmentsponsored project called Plume (French for feather) to industrialize the process, which relies on a combination of moving mould cores, a chemical blowing agent, and lightweight reinforcing fillers. The project starts in September, and will run for two years. It will have a total budget of €2.4 million. The project will also involve the participation of several other French companies: compound producer Sumika Polymer Compounds (a Sumitomo Chemical Group

company) based in Saint-Martin de Crau; mould-maker Cero, in Nantes; polymer science research laboratory IMP at the University of Saint-Etienne; and Sophia Antipolisbased Cemef, a research laboratory from Mines ParisTech, associated with CNRS, with expertise in process simulation. “Incorporation of parts made by the Plume process could lead to a total vehicle weight reduction of between 5 and 7kg,” said Elsa Germain, research and innovation engineer at Mecaplast. “This will have an important knock-on effect on fuel consumption, with resulting carbon dioxide emissions falling by around 0.5-0.7g/km.” The process is similar to one already used in Japan for production of parts used by such automotive companies as Honda and Toyota. However, that process has some limitations, especially in terms of surface finish, since the parts are made with talc-filled polypropylene (PP). The Plume

process will use newly-developed compounds that contain little or no talc. Instead, they incorporate new reinforcing fillers that not only yield improved surface quality but also help reduce part weight by as much as 7%, without loss of mechanical properties. The new compounds, which are based on PP impact copolymer and are being developed exclusively for Mecaplast, also have very good flow properties. Melt flow index is over 50 g/10 min. This is critical for the success of the Plume process. The Plume process In the Plume process, material is injected into a mould with moving walls that are initially in the forward position. Once all the material has been injected, and the skins of the part have solidified, the walls retract. This lowers the pressure in the mould cavity, and chemical blowing agent, until now dissolved in the melt, comes out of solution in the areas of the part that are still fluid to create a cellular structure that fills the newly created space. The foaming process on its own (disregarding compound formulation) enables a weight reduction in the part of at least 30%, compared to a conventional solid moulding. Cemef will look at melt rheology and its effects on the process and it will also carry out analysis of the microstructures created by the chemical foaming. IMP-UJM will study the mechanical behaviour of parts made under various conditions. Mecaplast plans to trial the process on two components, a tailgate interior trim and exterior beltline mouldings. The beltline mouldings will be produced in two versions, one with a grained surface that will require no painting and another that will be paintable.

A stool, an end table or nightstand, or an attractive lamp, the Lightbox can add a cubical glow to any space big enough for an 45cm cube. The product supports up to 90kg.

Recycling at NPE2012 collects twice as much FOR five days in April, the NPE2012 international plastics exposition transformed the Orange County Convention Center (OCCC) in Orlando, Florida into a virtual manufacturing city, generating many tons of industrial scrap in addition to packaging and other postconsumer waste. None of it, however, ended up in landfills, according to the OCCC and SPI: The Plastics Industry Trade Association, which produces the triennial NPE. Final figures provided to SPI by Maine Plastics, Inc., the official recycler for NPE2012, indicate that the production scrap generated by machinery operated on the show floor by 56 exhibitors participating in the ‘NPE Recycles’ programme amounted to 118 tons. This was more than double the 57 ton total for NPE2009, where 45 exhibitors participated.

Octal PET system cuts cost of scrap THE new direct-to-sheet process (DPET™) from OCTAL eliminates five energy-intensive stages of the conventional sheet production process (pelletizer, SSP, compactor, dryer and extruder). In the new system the PET melt arrives at the calendar stack heated to the proper temperature and does not have to be dried and re-melted from the granular form. The system also offers absolute traceability as the resin is constrained to one source providing the origin of the resin. The uniformity of the sheet has allowed

OCTAL to design a winder that constructs precision rolls with unnoticeable weave and near perfect formation. Thermoformers benefit from this advantage by being able to minimize side trim. DPET is manufactured to a typical caliper variation of +/- 1%, allowing thermoformers to specify a thinner sheet and still achieve package performance in finished trays. DPET can be run at a 10% faster cycle time and at temperatures up to 5 degrees lower than conventional APET, while still retaining clarity and gloss.

Training raises complicated set of challenges in SA Response to ‘Letter to the Editor’ by Dave Ransom in June/July 2012 issue: I most sincerely thank Dave Ransom for his response. He has helped to point out the complicated situation with trying to train the members of an industry in South Africa. The whole point of the creation of the initiative to link education and training to BBBEE is to create funding from which to provide the best and most appropriate interventions that will lead to a better educated workforce in the rubber industry. The proposal is based on a holistic view of the industry and in no way meant to denigrate the efforts made by individual private agencies to provide a training service. We would not even be talking about this issue if the current service providers had the support and the capacity to educate and train the substantial numbers that are currently employed in the Industry on a long term basis. I am the ďŹ rst to acknowledge the positive efforts made by the

two private companies mentioned and, when still in business, I made use of their services. However, we are not talking about rubber skills training only. We need to be able provide the resources to educate and train all of the members of a substantial industry from shop oor to senior management, if we are to survive and prosper as a deďŹ ned industry. National education, whether we like it or not, is based on national structures. They are the best we have and are the legal basis for the development of education and training courses that will lead to qualiďŹ cations that are portable and recognised within general industry in South Africa. This is the rule for national qualiďŹ cations that qualify for substantial SETA grants and funding. This effort by the IOMÂł, as the only professional body in the industry and trying to make a difference, is to create the facili-

ties for members of the rubber industry to educate and train their staff. The services of the private companies mentioned would be expected to be an integral part of this process. The scope of the vision, however, is to provide opportunities for education and training that are far greater than those currently being offered. In my opinion, a broader view has to be taken if we are to retain anything of a viable and progressive local industrial rubber industry in the face of the competition coming from the developing world. Just take a look at what was 20 years ago and what is now. We can no longer compete in mass markets and so specialised niche markets are the only opportunity left. The success criteria in a niche market are service and expertise. Have we got them? Dave Duncan AUGUST / SEPTEMBER 2012 105

‘How valuable is your time?’ New on-line modelling tool simplifies tie layer selection

This meat packaging example illustrates the complexity of today’s packaging and the role tie-layers play in bonding dissimilar materials

THE second in a series of online predictive modelling tools from DuPont Packaging promises to simplify tie-layer material selection, a critical step in multilayer packaging design. “Selecting the right coextrudable adhesive ensures dissimilar polymers bond – and stay bonded from manufacturing through consumer use,” said Barry Morris, PhD, DuPont Packaging technology fellow. “In today’s world, designers have hundreds of options and their performance varies based on the packaging structure’s manufacturing process, the contents of the packaging, the environment that the packaging is exposed to – selecting the right adhesive is critical; it doesn’t have to be frustrating.” DuPont, which supplies the world’s broadest range of specialized co-extrudable adhesive resins, offers the DuPont Tie Resin

Selector as the first step in selecting the best resin. Users start by identifying two materials to be joined together and the Selector provides a short list of recommended grades of DuPont tie resins grouped by type of extrusion process. The Selector includes links to data sheets for recommended grades, to other relevant literature and to a customer service contact for sample ordering and inquiries. Its database includes more than 40 grades of DuPont™ Bynel® coextrudable adhesives plus several grades of DuPont Elvax® EVA copolymer and DuPont Nucrel® acid copolymers. “Identifying the right candidates early in the design process can help avoid expensive, iterative trials and, of course, costly errors late in the process,” said Morris. “It’s also a global tool with answers tailored to special needs in each region.” The Tie Resin Selector is the latest addition to a suite of tools that DuPont uses with its customers to help optimize packaging structures and processes. Two of these are now available on the web; the other is the DuPont™ SAVE tool for calculating total packaging cost using alternative sealants. “DuPont computer modeling and simulation tools save development costs and time by helping our customers identify cost-effective material combinations and processes,” said Mike Hiteshew, DuPont Packaging global eMarketing leader. “Stay tuned for more web-based tools in the future.” Drawing from an extensive mix of adhesives, sealants, modifiers; barrier and peelable-lidding resins, DuPont Packaging & Industrial Polymers works with customers around the world on packaging initiatives that help protect the product, environment, improve shelf appeal, convenience and re-

BOOKS

Protecting plastics & rubber THE worldwide market for stabilisers and other additives which protect plastics from degradation when exposed to heat and light will achieve revenues of almost US$4.8 billion by 2018 forecasts Oliver Kutsch, CEO of Ceresana Research. According to the new study of Ceresana, the Asia-Pacific accounts for about half of all demand, followed by Western Europe and North America. Heat stabilisers are mainly needed for construction materials made of PVC: More than 85% of all stabilizers sold during 2010 were used in profiles, pipes, and cable jackets. The market for light stabilizers is growing worldwide. Particularly HALS (Hindered Amine Light Stabilizers), used in products made of polypropylene or polyethylene, will see great increases in demand. Ceresana Research anticipates that the Asia-Pacific region will continue to strongly influence the stabilizer market over the next years. In addition, South America, Eastern Europe, and the Middle East register above-average growth rates of 3.5% to 4.7%. The study summarizes the most important facts on the different types of heat and light stabilizers on 567 pages. The global market is analysed in detail, above all the 17 countries with the largest demand. Most important application areas, such as pipes, films, and elastomers, are examined one by one. www.ceresana.com

Asia’s middle class driving BOPP film markets THE BOPP film industry continued to show robust growth during 2011 with demand advancing by 5.5% compared with 2010 to top 6 million tons for the first time, according to the latest report on the global BOPP film market from AMI Consulting. Demand growth was slightly down on 2010 which had been the bounce back year from the financial crisis for most markets around the world. Global demand is increasingly being driven by developments in Asia, particularly in China, India and Indonesia. With over 60% of BOPP usage occurring in food packaging, it is the growth in demand in these countries for an ever-widening variety of packaged foods sold through supermarket outlets that is one of the main drivers for this material. With large, youthful and growing populations, increased urbanisation and rising incomes it is the developing markets of Asia that will continue to underpin growth in BOPP film demand. AMI’s analysis shows that China alone now accounts for 40% of global production

and demand and on its own accounted for 2 percentage points of the global growth achieved in 2011. It accounted for 95% of all new capacity installed in 2011. Although production has and will continue to be primarily to serve the domestic market, the volume of output now is such

that even modest export volumes have the potential to disrupt other markets. Chinese exports, which AMI estimated were 6% of production in 2011, are largely targeted at neighbouring Asian countries, but material can turn up in any part of the world from time to time. AMI believes the BOPP film market has the potential to continue growing at a strong rate of 6-7%/year over the next five years. This would add another 2.3 million tons of demand. As was seen in 2011 the strongest growth is likely to continue to be in India, driven by the development of the organized retail sector opening up to foreign investment; China, driven by government initiatives to increase domestic consumption and raise living standards of its rural poor; and the Middle East and Africa, driven by general economic growth within this resource rich region. BOPP films - the global market is a detailed market report from AMI Consulting. www.amiplastics.com AUGUST / SEPTEMBER 2012

Production efďŹ ciency with Arburg at FAKUMA THE theme of lightweight construction, which is growing in importance, is the focus of the Arburg display at the FAKUMA show in Friedrichshafen, Germany, from 16–20 October. One exhibit is of the new ‘long-ďŹ bre direct injection moulding’ process developed with German Plastics Center SKZ in WĂźrzburg. The process allows inline feeding and enables longer ďŹ bres than ever before to be processed, so that lightweight injection moulded parts with thin walls and high strength can be produced. Particle-foam Composite Injection Moulding (PCIM) is a joint project with Krallmann and Ruch Novaplast in which a foamed part is combined with plastic for the ďŹ rst time. The two components are bonded, so that there is no need for subsequent assembly steps and a ďŹ nished part is produced in a single step. This production of composite components made from particle foam and injection moulded plastic opens up a whole ďŹ eld of new options for the electric mobility, lightweight construction and insulation sectors. www.arburg.com

Solar Impulse to attempt flight to Africa Longest flight planned for manned solar plane

SOLAR Impulse, the innovative solarpowered airplane, is to attempt its longest flight, from Switzerland to Africa. The aircraft uses technical expertise, high-tech polymer materials and energy-saving lightweight materials from Bayer MaterialScience, an official partner to the visionary Swiss bid to fly night and day around the world without fuel. The testing 48-hour journey of over 2 500 km, which will cross the Pyrenees and the Mediterranean and end in Morocco, follows successful test flights including Solar Impulse’s first international

flight, from Switzerland to France and Belgium, in 2011. The flight will be excellent training for the round-the-world trip planned for 2014. Project originators Bertrand Piccard and André Borschberg will take turns to fly the aircraft, with a scheduled intermediate stopover near Madrid, Spain to change pilots. The trip will coincide with the start of work in Morocco’s Ouarzazate region to construct the largest solar power plant ever built. The Moroccan Agency for Solar Energy (MASEN) is leading the implemen-

tation of the integrated Moroccan Solar Plan, which aims at developing a minimum power capacity of 2 000 MW by 2020. Leverkusen-based company Bayer MaterialScience became an official partner of the Swiss Solar Impulse project in 2010. Since then, more than two dozen researchers have been working at the company’s laboratories in Leverkusen, Dormagen and Krefeld-Uerdingen on ideas for lightweight construction and energy efficiency. Material solutions are, for example, part of the plane’s pilot cabin, the wings and the motor gondolas.

High-tech on the soccer pitch

in heavy rain, its weight increases by no more than 0.1%, which means that the players are able to control it better. The ball’s name and design are every bit as traditional as its insides are modern. The Tango debuted at the 1978 World Championship in Argentina, and its successors provided for plenty of goals at subsequent championships in the 1980s. The new ball sports the classic black and white design updated with colourful accents. The host nations’ national colours – red and white for Poland, yellow and blue

for Ukraine – have been immortalized in the triangles. Another unique feature is that unlike its predecessors, it does not have a glossy surface – matte balls are currently in vogue. Bayer MaterialScience’s involvement in sports goes beyond soccer. Safer, more stable, faster – sports equipment such as skis, snowboards and inline skates also benefit from high-tech plastics. This also applies to other sporting goods. Raw materials from Bayer MaterialScience can be found in goggles, helmets and shoes.

High performance materials for fast, robust & precise soccer ball THE games at the European Soccer Championship will be played to the rhythm of the ‘Tango 12’, a cutting-edge synthetic ball that is fast, robust and precise. The adidas ball sports a new design and is based on proven materials from Bayer MaterialScience. The surface texture of the official European Championship ball feels like denim, allowing for better ball control. The shell is made up of five layers with a total thickness of 1.1 mm. These layers make the European Championship ball robust and accurate. The middle layer – an Impranil® foam containing millions of gas-filled microcells – is responsible for the optimal contact of the ‘Tango 12’ to the foot. The upper layers protect the foam from external influences and help keep the ball looking new longer. Another specialty material from Bayer MaterialScience is used for a patented thermal adhesive layer that makes the ball virtually impermeable to water. Even 112
