Material

  Ethylene Propylene Rubber (EPM, EPDM)

EPM is a Copolymer of ethylene and propylene, EPDM is terpolymer of ethylene and propylene with a small amount of a third monomer (usually a diolefin) to permit vulcanization with sulfur. Generally Ethylene Propylene Rubber posses excellent resistance to ozone, sunlight and weathering, and have very good flexibility at low temperature, good chemical resistance (many dilute acids and alkalis, polar solvents), and good electrical insulation property.

For EPDM the service temperature can be designed from -55℃ to 125℃ or up to 150℃.
