Common materials for rubber products include the following:
Natural rubber: Natural rubber is extracted from latex collected from rubber trees, and its main component is cis-polyisoprene. It has excellent elasticity, tensile strength and tear resistance, and is widely used in rubber products such as tires and tapes. Natural rubber softens at high temperatures, but crystallizes and hardens at low temperatures, and is not resistant to strong acids.
Synthetic rubber: Synthetic rubber is artificially synthesized by chemical methods, and has the characteristics of high elasticity, insulation, air tightness, and oil resistance, high temperature resistance and low temperature resistance. Common synthetic rubbers include styrene-butadiene rubber (SBR), butyl rubber (IIR), ethylene-propylene-diene rubber (EPDM) and nitrile rubber (NBR). These materials are widely used in industry, such as tires, conveyor belts, seals, etc.
Silicone rubber: The main chain of silicone rubber is composed of alternating silicon and oxygen atoms, and two organic groups are usually attached to the silicon atom. It has excellent high temperature resistance and is widely used in situations requiring high temperature stability, such as high temperature seals and insulating materials.
Fluororubber: Fluororubber has excellent high temperature mechanical stability and is suitable for sealing and wear-resistant parts in extreme high temperature environments. Its formula usually includes fluororubber, vulcanizing agent, cross-linking agent, inorganic filler, metal compound filler, etc.
