Both claim to offer high flexibility with minimal use of plasticiser for use in low-pressure hydraulic hose and low-pressure pneumatic/hydraulic tubing. Over time, the change in properties is negligible, even at temperatures up to 130°C. This is mainly because they also only use 5-7% plasticiser, compared to the incumbent materials that typically use 12-15%. Other benefits include low permeability, high yield stress/stiffness balance and a broad extrusion processing window, as well as a flexibility similar to PA12 but with better cold impact toughness.

Teknor Apex introduced a rigid, UV-resistant vinyl compound for outdoor applications, such as tubing for algae farming and biofuel production. Apex RE 9118A is a transparent compound with less than 15% haze. The formulation reduces the harmful effects of ultraviolet radiation on the PVC while transmitting wavelengths that are essential in processes like algae farming. The tensile, flexural, and impact properties of the compound are comparable to those of standard general-purpose rigid vinyl, says Teknor Apex. “Rigid vinyl provides a superior cost-performance alternative to the glass piping used in ‘green energy’ applications, as well as to high-cost engineered Erema’s new

rapidly and consistently through the period 2007 to 2012, averaging growth of nearly 10% every year. Slower years were between 2010 and 2013 where the global recession, extended monsoon season and the eurozone crisis slightly curtailed growth. Generally, growth for LL/LDPE has been growing at 1.4 times that of the subcontinent’s GDP growth. 84% of the subcontinent’s demand is accounted for by India. LDPE is produced in dedicated plants whereas LLDPE can be produced in swing plants capable of producing both high density as well as linear grades. Swing plants in the region have tended to favour LLDPE grades however the ability to swing between grades makes calculating capacity problematic. All subcontinent LL/LDPE production comes from India. Production has been consistently lower than local demand and hence the region has become increasingly dependent on imports. In 2011 Indian imports were 625,000 tonnes but this increased to over 785,000 tonnes in 2012 (50% of demand). To cope with fast growth in demand there will be a number of new Indian plants coming on stream in 2013-2015. BCPL, % change Reliance, GAIL and OPaL will be investing in HD/LLDPE swing plants whilst Reliance Industries also plans a 400,000 tonnes/year LDPE plant as part of its USD12 billion capacity 2011-2012 2012-2013 investment programme. While capacity is expected to exceed regional demand by 2015 overall the subcontinent will continue to rely on imports although India is expected to become 10.0% 8.4% a net exporter before 2016.

thermal conductivity similar to that of wood or PVC.” The material is protected from the weather by a coating or a laminated film, which reduces the risk of rotting or embrittlement. The profiles are produced by pultrusion. At K2013, Wacker presented Elastosil R 781/80, a silicone rubber filled with tiny magnetic particles. The compounds can be magnetised in the presence of a strong magnetic or electromagnetic field. The compound can be used to make magnetic profiles that stick to flat and curved or rounded metallic surfaces. Such profiles could be used by kitchen appliance makers, who tend to equip their products with magnetic seals. These seals can be costly to make, especially as the magnets must be incorporated into the rubber gasket by hand. Profiles made of Elastosil R 781/80 would be easier and more efficient to produce, and would retain their elasticity and flexibility at low temperature.

The company regularly delivers lines to make five-layer pipe, and has a concrete order for a six-layer line. “New waste gas standards will continue to drive these developments,” he said.

to such an extent that the extruder screw acts in the same way as a sharp cutting edge which now cuts the plastic. This helps the extruder to process more material in a shorter time and is more independent in terms of the pre-compacting level of the material. The inverse tangential configuration of the counter current system ensures that the extruder screw is filled virtually pressure-free with pre-heated material. “The screw basically takes what it needs,” said Michael Heitzinger, chief technology officer at Erema. “The extruder always has the ideal filling level and is never overfilled, which makes it much better to regulate.” Results from development trials (in cooperation with customers) with in-house waste from 30 micron LLDPE blown film show the effect of the new system on the increased process stability, productivity and flexibility of The KM-7L-

Recycling innovation Intarema is the name of the new core recycling technology from Erema. It is based on the company’s patented counter current technology, which Erema says combines flexibility and higher productivity with lower energy consumption. Inside a cutter/compactor, the rotation of the rotor disc that is equipped with tools forms a rotating spout so that material circulates the whole time. In the counter current system this spout now moves against the direction of the extruder. As a result, the relative speed of the material in the intake zone – when passing from the cutter/compactor to the extruder – increases 20

European polymer demand | markets

The global downturn and Eurozone crisis hit Europe’s economy hard. AMI’s Carole Kluth provides this exclusive analysis of what that meant for polymer demand in 2013 and what the future holds

When AMI published its last review of the European plastics industry in 2011 the market was making a tentative recovery from the effects of the global downturn of 2008 and 2009. However, the modest recovery seen in 2010 and through the first half of 2011 was beginning to run out of steam by the last quarter of 2011 thanks to the emerging eurozone crisis and for 2012 growth in the industry stalled. The drop in demand over 2012 and 2013 has been far

However, the countries of Southern Europe are expected to continue to see shrinking market demand for some time yet. Given the modest outlook for polymer demand in the economies of the European continent, overall European demand is expected to average equally modest growth of just over 1% a year for the five-year period 2012-2017. Volume demand will mainly be driven by developments in Central Europe, where the market is expected to continue to grow at nearer 3% a year. In contrast, growth in western Europe will average less than 1% a year.

mance balance for plastics manufacturers by allowing throughputs to be measured in real time. The product combines the benefits of TSM’s patented reverse auger technology with a fast, responsive throughput measurement. “The fast, responsive throughput measurements will benefit plastics producers by giving them real-time control,” said Declan Byrne, director of sales. “This will improve the accuracy and consistency of their end product, reduce waste and improve cost efficiency.” A new control algorithm, developed in conjunction with a UK university, delivers accurate control that allows performance to be maintained at lower setpoints. The small footprint makes the machine ideal for new or retrofit installations. The blender development came about in response to an industry need for highly responsive control systems. “Plastics producers are increasingly looking to use less raw materials to make more consistent end-product and decrease wastage,” said Byrne.

Its new product, Scona TSPE 2102 GAHD is a WPC modifier based on HDPE, which is highly functionalised with maleic anhydride. Recommended loading is 1-4%, depending on fibre content. The material’s improved compatibility facilitates easy processing even with a low shear, says the company. At the same time, the product is grafted higher, so provides greater functionality than other products on the market. This allows for a lower dosage.

The company is also launching a range of reducing and multi-port tees.

Energy efficiency Also in North America, Rehau has expanded its range of PEX-a pre-insulated energy transfer pipes with the addition of Rauvitherm. Designed for small- to medium-sized projects, it features closed-cell crosslinked polyethylene (PE) foam, which combines insulating properties with high flexibility. Its HDPE outer jacket is designed to withstand typical outdoor conditions, and is bonded to the pipe’s outer insulation layer to reduce risk of water infiltration. Rauvitherm is available as a single-pipe solution in 25-125mm diameters, and as a dual-pipe solution in 25-63mm diameters. At the same time, the company’s Raugeo PEX-a piping system has been certified for use in Canada following revisions to the CSA Group’s new Standard C448/2013

PEX updated Borealis showcased a number of polyolefin pipe grades at K2013, including a new version of its crosslinkable PEX-a compound. It relaunched its enhanced HE1878E-C2, claiming it is the first fully-stabilised, ready-compounded PEX-a to achieve Class 5 listing. The Class 5 listing corresponds to the highest chlorine-resistance rating in accordance with the ASTM F876 standard for PE crosslinked pipes using the ASTM F2023 test method. ASTM F876 is the standard specification for PEX tubing in North America. The advanced qualification of Borealis HE1878E-C2 opens up a new range of opportunities for pipe producers in North America, while enabling producers in Europe, Asia and the Middle East to gain a competitive edge thanks to product differentiation, says the company. The PEX-a pipe boasts benefits such as enhanced durability, high

Design and Installation of Earth Energy Systems. The previous regulations specified the use of non-crosslinked PE pipe for ground heat exchangers, but the revised standard means that PEX-a pipes and F2080 cold-expansion compression-sleeve fittings may now be used in these applications in Canada. “Specifiers and installers across Canada have been requesting the option to use PEX-a systems, in some cases to take advantage of its unique fitting and manifold options,” said André Carrier, chairman of the CSA C448 technical subcommittee. “PEX-a pipe and cold-expansion compression-sleeve fittings have been used in Canada for several decades in applications such as radiant heating, snow and ice melting, and water service and distribution.” Simon Koenig, business team manager for renewable energies at Rehau, said the installation and long-term performance advantages of PEX pipes would be put to good use in emerging applications. “This is a great step forward for the Canadian geothermal market, at a time when the cost and supply challenges of traditional energy sources are the catalyst for considering and employing earth energy systems,” he said. He added that PEX-a pipes provide an advantage in vertical installations, as they are flexible enough to be formed into a compact U-bend for insertion into a standard 13cm (5in) borehole without the use of joints or connections. And, as the Raugeo coils are extruded and fabricated in Rehau’s North American production facility, the pipe can be delivered to the work site with the U-bend already formed. “Where connections are required, the unique properties of PEX-a allow the use of ASTM F2080 Everloc cold-expansion compression-sleeve fittings that install quickly and without the use of heat or electricity, in any weather conditions,” he said. He said that the pipes are also approved for use with HDPE electro-fusion fittings (as per ASTM Standard F1055), in installation temperatures as cold as -20°C (-4F). “Raugeo PEX-a is a reliable piping system engineered for tough ground conditions,” he said.

extruder of the month

Reddiplex Head office: Date founded: Managing director: Ownership: Profile:

Droitwich, UK 1969 Owen Boylan Private Reddiplex supplies a wide range of both standard and custom extrusions to customers across the world, from its factory in the UK. Its products include rigid, flexible, solid rubber and sponge rubber extrusions, in materials ranging from PVC to polycarbonate. The main industries it supplies are building and construction, automotive, aerospace and marine.

Plant locations:

The company has a single 30,000 sq m manufacturing plant in Droitwich in Worcestershire, UK, from which it supplies its entire range of products. In addition to extensive production facilities – for single hardness, co-extrusion and triplex extrusion – it boasts an in-house design department that can design and manufacture extrusion dies.

Recent projects:

Reddiplex recently supplied a decorative cover strip to JSC Minsky Avtomobilny Zavod (MAZ), one of the largest automotive manufacturers in central and eastern Europe. The cover was clipped into an aluminium drain section that runs the entire length of a bus chassis. To decorate the part, Reddiplex used an embossing machine to roll the desired pattern onto the profile, after it had been extruded. Recently, the company also supplied a sealing system to Lewmar Marine, which incorporates solid EPDM and sponge in a single profile.
