Ethylene Propylene Diene Monomer(EPDM)
Ethylene Propylene Rubber (EPR) is a Copolymer of ethylene and propylene. Furthermore, EPDM it is a terpolymer of ethylene and propylene with a small amount of a third monomer (usually a diene) to permit vulcanization with sulfur. Generally, EPDM possesses an excellent resistance to ozone, sunlight and weathering, and has very good flexibility at low temperature, good chemical resistance (many dilute acids and alkalis as well as polar solvents) and good electrical insulation property.
