1. MANUFACTURING PROCESSES 1.1 EXTRUSION PROCESS

1.1.1. Netlon extrusion process. Counter-rotation

The mesh extrusion process is the origin of all our products. Controlling all the parameters involved in this process with precision is something that only the best staff and core technology can achieve. The Intermas group has more than 50 years of experience in extrusion processes, as well as the staff and technology necessary for the manufacture and development of the two main manufacturing processes currently available for extruded plastic mesh: The Netlon system and the Trical system. The end result is the fact that we have an enormous available capacity for designing, together with our clients, products that are custom-tailored to each individual need.

The Netlon process consists of placing two dies within the head. These dies will rotate in opposite directions in relation to each other. Both dies have grooves. These grooves are the only cavity through which material will flow towards the outside. Due to the dies’ rotation, the mesh’s shape will always be rhombus-shaped.

Plastic Mesh Extrusion Plastic mesh extrusion is the continuous process of transforming oil-derived materials, such as polymers, into tubular or flat fabric or mesh. The materials are melted during the process, and at the end form a tubular or flat structure with holes in it. In contrast to the weaving process, the extrusion process results in a final product that is already formed by threads that have been joined and welded during the process. The main parts of this process are as follows: 1. Mixture. Process of mixing raw materials, colorants, and additives for homogeneous and constant dispersion. 2. Melting. Stage during which the screw conveys, homogenizes, and applies the material while the latter moves towards the machine head. The material reaches its melting point during this process. 3. Forming. This is the main part of the process, during which the material flows through the head’s interior and reaches the die that will give the mesh its final shape. 4. Cooling. The mesh is put in contact with water in order to make it return to its solid state, so that it can be handled. The output mesh shape after leaving the head is always tubular. 5. Cutting. In cases in which a flat mesh is required, the mesh must be cut inside or outside the water. 6. Drying and rolling. Process through which water is eliminated completely and mesh rolling is begun.

1.1.2. Trical manufacturing process. Oscillation The Trical process is characterized by the fact that only one of the dies moves. The oscillation movement causes the material to flow when the die is opened and to form rings that create the transversal threads. The final product is a tubular mesh with angles of approximately 90 degrees. Once the plastic mesh has been finished in its first stage with either main manufacturing process, it can be subjected to other processes that will considerably change the product’s initial characteristics. The main subsequent processes that we currently have are: orientation, bi-orientation, and lamination.

1.2. Orientation & Bi-orientation process Orientation is the process of linearly orienting the molecular chains that form the polymers in the same direction. In order to do this, it is necessary to heat the plastic mesh again until an optimal temperature for stretching the mesh is achieved – in a longitudinal direction for oriented meshes and in both longitudinal and transversal directions for bioriented meshes. The result is a much greater traction resistance and a decrease in weight due to a reduction in thread diameter. This way, specific products that are custom-tailored to the demands of sectors with very special applications are obtained.

Plastic structures Plastic mesh can have a large variety of shapes, colors, structures, and finishes. There are thousands of different meshes. The main parameters that define the mesh are structure (thread shape; knot; thickness; angle and distance between threads), materials (raw material, additives, and colorants), width, and color. There are various plastic mesh extrusion processes, but the two most common ones are, without a doubt, the Netlon (counter-rotation) process and the Trical (oscillation) system.

1.3. Weaving process

2.1. FILTERS

Intermas has also been one of the main manufacturers of woven mesh for many years. Moreover, we have recently made several industrial investments that have greatly expanded our capacity. Woven mesh also has its origins in extrusion. The first part of woven mesh manufacture is the production of the monofilament or raffia that will be woven. The raffia is made by hot cutting and orienting a plastic film or sheet, which results in a very flat and usually thin structure. Due to the rectangular form of their cross-section, raffia threads are very flexible and have a larger flat area in function of weight than monofilaments. Depending on the technology used, there are two different available textile processes at Intermas: Flat (drawn) knitting, and warp (“raschel”) knitting.

Advantages · High permeability. · No humidity retention. · Good resistance to hydrolysis. · Possibility of adding antimicrobial additives. · Possibility of adding flame-retardant additives*. · Recyclability. · BOP bi-oriented mesh: rigidity and uniformity regarding mesh stress.

1.4. Lamination process In certain applications, the extruded mesh must function as a support for a different material. Lamination is the process of joining a plastic mesh with another material(s). This coupling results in multiplied efficiency. The process is carried out by heating until the necessary temperature for the two materials to be joined is reached, and then applying pressure so that the melted molecules of both materials integrate. The most common products currently being incorporated into plastic mesh are “nonwovens” and plastics sheets. In the case of “nonwovens,” the mesh functions as a support and as a draining channel, while the “nonwoven” functions as a filter. In the case of plastic films or sheets, the mesh functions as a support and as a draining channel as well, and the plastic sheet functions as a waterproofing element. In some cases, the mesh can be laminated on both sides.

1.5. Mechanics and finishing processes In addition to the aforementioned processes, Intermas carries out several other additional finishing processes for many of its products, all with the objective of facilitating and improving their functionality at the moment of application. Processes such as transversal cutting, die cutting, punching, welding, incorporation of strips, sewing, and many others make the use of these products a lot easier for our clients.

· Extremely flat mesh: makes adhesion to nonwovens easier. · Width: up to 2 meters. · Filters for automotive / transportation air conditioners. · Home heating / air conditioning systems. · Public buildings (hospitals, airports). · Vacuum cleaner filters. * provides compliance with the FMVSS302 standard for the automotive market.

Our products are implemented in all types of fluid-filtering technologies that are used in various fields within the industry. Throughout the course of its existence, Intermas has developed a large number of products that have become essential elements in the manufacture of filters (for both air and liquids), contributing solutions such as support for folding, separation, reinforcing, etc. The unique characteristics of these types of mesh, together with Intermas’ manufacturing capacity and quality control system (ISO 9002 and 14001 certifications), turn them into significant alternatives to be taken into consideration when developing and designing new filters. Intermas also offers solutions based on combinations of different core technologies, like lamination (meshes with nonwoven fabrics, films, etc.). The TEXNET range of products is the result of this.

2.1.1. Folding supports in air filters Intermas offers an important range of products for media support and folding that is commonly used in air filtration. These products allow the use of very efficient materials with very high permeability (nonwoven fabrics obtained by means of meltdown or needle punching).

2.1.2. Separators for reverse osmosis filtration membranes When it comes to the filtration of liquids, reverse osmosis has become the preferred technology for applications with high demand. Intermas offers biplanar and triplanar products for application in the field of reverse osmosis, as “spacers” between membrane layers. These products are custom-tailored to the needs of each client.

2. MARKETS 2.1.3. Hydraulic filter mesh

2.2.2. B.O.P. Mesh

Mesh manufactured with nylon (polyamide) is an attractive and ecological alternative to metal mesh used in fiberglass-based media-folding, which is traditionally used in hydraulic filters. Nylon’s chemical structure makes it capable of standing the temperatures and environment (oils) of hydraulic systems.

BOP (bi-oriented polypropylene) mesh is the result of important advances in modern plastic transformation and technology. By means of molecularly orienting the chains that constitute the polymer (polypropylene), these products contribute an excellent traction resistance with very small weights and very low residual deformation. This makes them appropriate for diverse applications in the mattress market, such as separation of padding layer springs, reinforcement of needle-punched and padded elements, protection of padding with latex or polyurethane foams, etc.

2.1.4. Automotive applications: mesh for oil and fuel filters

2.2.3. Non-woven mesh

Our polyester mesh range is the answer to recycling problems resulting from automotive oil and fuel filters. The compound resulting from a PBT mesh and a filtering polyester “nonwoven” fabric not only allows for excellent folding, but also for the manufacture of a filter with one single material that is 100% recyclable. A new generation of filters is born. The compound resulting from a PBT mesh and a filtering polyester “nonwoven” fabric not only allows for excellent folding, but also for the manufacture of a filter with one single material that is 100% recyclable.

After research and development in the manufacture of laminates, Intermas has launched a new range of TEXNET products. This revolutionary innovation in the market adds the advantages of BOP meshes (traction resistance, low deformation…) to the advantages to nonwoven products (total separation, continuity and smoothness) at competitive prices. These products create new possibilities in applications such as padding reinforcement, anti-dust separators, etc.

2.1.5. Sheaths

2.2.4. Extra-strong mesh

Intermas is the world’s largest manufacturer of extruded tubular mesh. These products, made of polyethylene or polypropylene, offer great advantages as sheaths in the manufacture of different kinds of filters. We have a wide available range that can be seen on our website: www.intermasgroup.com

In certain applications (high-quality mattresses) and mattress parts (lumbar zone), it is necessary to provide support / reinforcement, which Intermas’ extra-strong mesh more than provides.

2.2. FURNITURE

2.3. PROTECTORS

Our mesh and compounds are used successfully in mattresses and other furniture industry products.

Intermas mesh can be used to provide an efficient and cost-effective protection for all kinds of manufactured objects. These innovative materials, manufactured with the company’s core technologies, offer a unique protection and packaging advantages for a wide range of industrial products.

2.3.1. Mesh for protecting and packaging industrial products and consumer goods

2.2.1. Mesh for mattresses Intermas’ various types of mesh and composites offer vast possibilities in the manufacture of mattresses due to an excellent combination of weight, resistance and functionality, which in turn makes them extremely useful in all their different applications. These products guarantee a maximum quality in mattresses and a great efficiency during manufacture.

Thanks to its biplanar structure, it prevents from direct contact between surfaces, and therefore scratches and any other type of damage that could result from handling or transportation. The high elasticity of extruded mesh turns it into a material ideal for this application, since it’s very easy to place it on the parts that need to be protected, and does not take up warehouse or maintenance area space. In certain applications, it is also important for the packaging product to allow breathing or spraying, impregnating, or immersion finishing treatments (for oils, lubricants, etc.). A key advantage in our current environment is that protective mesh is manufactured with recyclable and nonpolluting raw materials, which makes their final recovery tremendously easy.

2. MARKETS 2.3.2. Tubular protection mesh

2.4.1. Mesh for car seats and cushions

Our mesh can be used to protect mechanical parts and composites, tubular products (gas bottles, chair legs), ceramic and crystal products (toilets, wine bottles, perfumes), etc. - more than a hundred applications that require an effective and competitive manner of separating and protecting the elements during handling and transportation. The elasticity of this mesh, as well as its different available diameters, is ideal for protecting tubular or cylindrical elements of all kinds.

Extruded and bi-oriented mesh is the main alternative for reinforcing polyurethane foam, which is used as padding in car seats. The cost / traction resistance ratio greatly favors these materials when compared to traditional reinforcement materials such as polyamide-woven or polyester-woven mesh, which were the materials most commonly used in hot molding technology (in which very high temperatures were reached within the molds), but which represent an extra cost in the cold molding systems that are currently used. Intermas has managed to further its participation in this market with the new range of TEXNET products, which combine the advantages of nonwoven spun bond materials (made of PP) with our extruded mesh (with or without bi-orientation).

2.3.3. Pallet separator Extruded mesh is also very effective for separating and securing parts on pallets, on which it provides a gap between different layers or levels, and therefore prevents scratches and damages to products. The product is supplied in rolls, with widths that are optimal for palletizing, and is manufactured with a special polymer mixture in order to prevent excessive shifting during transportation.

A reinforcement for molded foams that is consistent through time Its resistance is superior to that obtained with conventional nonwoven materials –needle-punched, spun bond, air laid, melt blown, etc.– which deform over time due to their own characteristics. In the case of BOP mesh (biaxially oriented polypropylene), the polymer chains are molecularly oriented during the manufacturing process until there is very little remaining elongation, which effects an effective foam reinforcement across time.

2.4.2 Mesh for reinforcement of rigid and semi-rigid automotive components

2.3.4. Snake “Wrap system” Extruded mesh constitutes an extremely efficient system for securing flat, round products (i.e. can lids) on pallets by means of the system known as “snake wrapping.” The use of mesh is particularly appropriate for products that come out of temperature-based process manufacturing lines, in order to prevent condensation.

Rigid and semi-rigid polyurethane foam is a very competitive solution for manufacturing certain automotive parts and components, such as roofs, trunk trays, and soundproofing. These products are constantly reinforced with fiberglass materials, which contributes enough rigidity at reduced costs. However, there is a large and growing demand for recyclable materials on behalf of automotive manufacturers, since they reduce the impact on the environment at the end of a car’s life. Our polyethylene and polypropylene mesh offers an advantageous alternative to fiberglass for the reinforcement of polyurethanes at inviting costs. These products also contribute to the components’ recyclability, since the final product can be handled entirely like a plastic (which is not the case with fiberglass). Intermas’ mesh is also efficient as reinforcement for certain delicate areas in seats (such as the airbag compartment) at very low costs.

2.4. AUTOMOTIVE PRODUCTS Extruded and woven Intermas mesh constitutes a range of products for the reinforcement of various types of polyurethane foams used in the automotive industry. These products are the result of years of research and of the combination of the company’s core technologies: extrusion, orientation, lamination, and plastic fabrics. They are used for the reinforcement of flexible, semi-rigid, and rigid polyurethane foams. Intermas also works actively with its clients in new material and application development programs, maximizing the efficiency and performance of automotive components and contributing the maximum possible value to them.

2.5. COMPOSITES During the last few years, Intermas has developed a wide range of mesh types for the “composites” industry, with the purpose of offering this sector specific products for each need. Intermas mesh provides the necessary quality and reliability for the distribution of resin by means of infusion processes. Our R&D department develops specific products for each client, providing the product’s necessary characteristics in accordance with each specific manufacturing process. Sectors such as aeronautics and wind power are using our mesh with optimum results.
