EPDM EPDM rubber ring is a copolymer synthesized from ethylene and propylene. It is a third monomer, usually a ternary copolymer of diene. Provide rubber vulcanization, referred to as EPDM rubber ring. Generally, the material performance of EPDM rubber ring has excellent ozone resistance, sunlight resistance and weather resistance. It has good elasticity at low temperatures and good chemical resistance, such as many diluted acids, alkalis and polar solvents. In addition The electrical insulation properties are also good. The material properties of EPDM rubber ring are as follows:
