Natural rubber has high elasticity at room temperature, slightly plastic, very good mechanical strength, low hysteresis loss, low heat generation during multiple deformation, so its flexibility is also good, and because it is non-polar rubber, so its electrical insulation performance is good.
Ethylene propylene diene monomer (EPDM) is a semi-finished product of rubber products, with excellent aging resistance, water-proof.Mainly used in industrial miscellaneous parts (seals, oil seals, O-gaskets, rollers, insulating pipes.
Styrene-butadiene rubber (SBR), also known as polystyrene butadiene copolymer. Its physical mechanism performance, processing performance and product use performance are close to natural rubber. Some properties such as wear resistance, heat resistance, aging resistance and vulcanization speed are better than natural rubber. It can be used with natural rubber and a variety of synthetic rubber. It is widely used in tires, belts, hoses, wires and cables, medical appliances and the production of various rubber products and other fields.
Contractile butadiene rubber is made from butadiene and acrylonitrile by emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. Its shortcomings are poor low temperature resistance, poor ozone resistance, poor electrical performance and slightly low elasticity. NBR is mainly used in the manufacture of oil-resistant rubber products.
Silicone rubber is a kind of synthetic rubber with cold and high temperature resistance because of its main chain structure. Among all kinds of rubber, it has the widest working range (- 100 ~ 300 C), excellent ozone aging resistance, heat aging resistance, light aging resistance, weather aging resistance and good electrical insulation.
Fluoroelastomer has incomparable superior properties, such as high temperature resistance, oil resistance, chemical resistance, good physical and mechanical properties and weather resistance, electrical insulation and radiation resistance, which are applied in automobile and motor vehicle industry. Because of its excellent high temperature resistance, oil resistance and medium resistance, it is mainly used as oil seal and O-ring
