Product Information

SAN (styrene-acrylonitrile copolymer) is a transparent copolymer of two transparent plastics: Formed by the copolymerisation of styrene (about 70%) and SAN acrylonitrile monomers (about 30%). This high-performance thermoplastic polymer is often used as a material for greenhouse or industrial glazing and shower cabins due to its weather resistance, rigidity, toughness and scratch resistance. CR (chloroprene rubber) is a synthetic rubber which is used, among other things, in vehicle construction and for heat-insulating sportswear. Hoses, cable sheathings, seals and drive belts based on chloroprene rubber are often used in the automotive industry due to their favourable combinations of properties. Dissolved in organic solvents, polychloroprene, like the polymer dispersion itself, is also suitable for various adhesives due to its good resistance. The worldwide consumption of chloroprene rubber including adhesives is estimated at over 300,000 tonnes per year. Physical surface treatment processes use high-energy electron, laser or UV radiation in this process or thermal processes such as flame treatment or electrical plasma or corona processes. They change the surface chemically and physically. When flaming plastics, an open flame is guided over the surface of the part to be joined at a defined distance and speed. The flame can be used in a reducing or oxidising manner, depending on the type of plastic to be flamed. This makes the component surface more energetic and easier to bond. By adding chemically reactive substances, the surface can be influenced even further. Plastic components are often fixed with the aid of adhesives to prevent them from slipping during further process handling. Acrylate-based adhesives in particular usually adhere very well to many plastics. They have a strengthening and supporting effect for load transfer and stress reduction. Acrylic adhesives, which are also used for permanent bonding, are characterised by short processing times and high strength to many plastics and elastomers. These adhesives achieve, for example, as 2-component adhesives on low-energy plastics such as PC, PMMA, PVC etc., good shear and peel strengths as well as good impact strength under dynamic loads. From the 3M Scotch-Weld series, even acrylic adhesives have been developed in the meantime, which provide good results on difficult to bond plastics with low surface energy without any surface preparation or primer. ABS - acrylonitrile-butadiene-styrene is an everyday plastic that is widely used today because of its surface hardness, high impact strength and good resistance to weathering, ageing and chemicals. Unfortunately, the low-energy ABS cannot be glued completely without problems with common adhesives and usually this is only possible after a surface treatment with the solvent methyl isobutyl ketone. However, ABS with ABS can also be bonded with methyl ethyl ketone (MEK) / butanone and dichloromethane (methylene chloride). Optimum procedure: Clean bonding surfaces, dry. Apply one coat of adhesive to one or both sides and allow to flash off briefly before pressing together. Further information.

time. 8. CLEAN-UP: Attach nozzle cap and store in molded tray. NOTE: Adhesive will not bond most polyethylene The Plastic Padding Super Steel comes in two tubes. When the contents of the tubes are thoroughly mixed, the curing process begins and you have a short period to place and use the mixture. The mixture hardens and soon cures to be as strong as steel. Features & Benefits:Foams are quite common in everyday life: They are used in everything from upholstery and mattresses to insulation materials. They are based on a wide range of plastics as raw materials. However, not every adhesive is suitable for every material. In view of the wide range of variants, it can therefore be useful to always test how the adhesive behaves on small samples of the material beforehand. Further information. Basically almost all plastics are suitable for foaming, e.g. polyurethane (PUR hard/soft foam), polypropylene, expanded polyurethane (EPP), expanded polystyrene (EPS), expanded polypropylene (EPE). The properties can be determined by the selection of the raw materials. For example, strongly cross-linked rigid foams are produced when short-chain polyols are used, whereas soft to elastic foams are produced with long-chain polyols. ABS (acrylonitrile-butadiene-styrene copolymer) is today an everyday plastic which is widely used because of its surface hardness, high impact resistance and good resistance to weathering, ageing and chemicals: For example, for sanitary pipes or housings of household and electrical appliances as well as for toys, plates and foils.

PA (polyamides) are high-strength and impact resistant. They have a high abrasion and wear resistance. Excellent sliding properties make them a preferred construction material in mechanical engineering or vehicle construction for slide bearings, gear wheels, dowels, screws and nuts or housings. Polyamides are insensitive to fuels and lubricants at temperatures up to 150 °C. A large proportion of polyamides are spun as synthetic fibres. The fibres have a high tensile strength and are used for textiles, climbing ropes, parachutes and hawsers, among other things. EPDM (ethylene propylene diene rubber) is used for sealing profiles. In contrast to NBR, EPDM has very good electrical insulation properties, excellent resistance to ozone and sunlight, and outstanding resistance to ageing.Silicones, with their low-energy, extremely repellent surfaces, are considered to be difficult or almost impossible to bond. Among the few adhesive products that show usable results here are, for example, new types of silicone transfer adhesives that, in combination with adhesive tapes, even enable efficient automation of series production processes - for example in the automotive sector. Further information. In contrast, the low-viscosity, hot-crosslinked silicone rubber (RTV/NV) is medium-elastic, has good flowability and low viscosity. It is therefore particularly suitable for the manufacture of elastic wax or relief casting moulds, casting moulds for figures or decorative panels, moulds for casting with epoxy / casting resin, cement, plaster or other flowable materials. When selecting an adhesive, one should consider what the bond must be able to withstand and what stresses the component will be exposed to in use. These are the questions about mechanical, dynamic and static loads, the temperature range, the influence of moisture, other chemical substances or UV radiation. At the same time, the list of requirements should include information on the parts to be joined, the production conditions, specifications for occupational safety and environmental protection, information on long-term resistance and quality assurance, as well as the selected test procedures and costs. At the same time, it's possible to use adhesive techniques to integrate properties into the component that go beyond the actual joining, such as insulation resistance to electrical potentials, sealing against gases and liquids, damping of vibrations, protection against corrosion and compensation of different joining part dynamics.
