EPDM rubber is a rubber formed by the copolymer of ethylene and propylene in solution, and then a third monomer (ENB) is introduced.EPDM rubber is basically a saturated polymer with very good aging resistance, good weather resistance, excellent electrical insulation performance, good chemical resistance, and good impact elasticity.The most important disadvantage of EPDM rubber is the slow vulcanization speed; it is difficult to use in combination with other unsaturated rubbers, and the self-adhesive and mutual viscosity are very poor, so the processing performance is not good.

According to the performance characteristics of EPDM rubber, it is mainly used in several fields that require aging resistance, water resistance, corrosion resistance, and electrical insulation, such as light-colored sidewall for tires, heat-resistant transport belts, cables, wires, anticorrosive linings, sealing gaskets, building waterproof sheets, door and window seals, household appliances accessories, plastic modification, etc.
