11 Polysulfide rubber (TR) has good oil resistance, hydrocarbon solvent resistance, atmospheric aging resistance, water resistance, and good low-temperature flexing properties. At the same time, it has very good adhesion to various materials. It is used as automobile sealing material, non-drying rubber putty and chemical equipment lining, road paint and oil-resistant paint, paint, oil-resistant rubber tube hollow glass sealing, etc.
12 Polyacrylate rubber (ACM and ANM) can be used at temperatures up to 175-200 degrees, with good air tightness, weathering resistance, heat resistance and oil resistance. The disadvantage is water resistance and poor low temperature resistance. The processing performance is difficult to master, and the vulcanization process is corrosive to the mold. Mainly used in automotive industry seals and special requirements of hoses, tapes, colleagues also used in the manufacture of wire and cable gloves, adhesives, etc. in contact with high-temperature oil.
13 Ethylene ethyl acetate rubber (EVW) can be used at a high temperature of 175 degrees for a long time. It has excellent flame retardancy and oil resistance, and the product has small compression deformation at high temperatures. Suitable for subways, high-rise buildings, and marine high-performance halogen-free flame-retardant wires and cables and other sealing products.
14 Chlorinated polyethylene (CPE) is a heat-resistant, weather-resistant, and flame-resistant special synthetic rubber with excellent electrical properties and chemical resistance. In addition, it has the advantages of oil resistance, ozone resistance, weather resistance, heat aging resistance, and flame resistance. , It is widely used in wire and cable with good flame and weather resistance, sealing products and industrial products such as hoses, tapes and rubber rollers that require temperature resistance, acid resistance and flame resistance.
15 Thermoplastic styrene-butadiene rubber (SBS) is currently the most economical thermoplastic elastomer with the largest output (7%). Its performance is similar to that of styrene-butadiene rubber. It has more elasticity, feel, rich color, format and low hardness products. The disadvantage is heat resistance and poor oil resistance.
