Ethlylene Propylene Diene Monomer is a copolymer of ethylene and propylene and a smaller amount of a diene monomer which forms chemically unsaturated ethylene groups pendant from the main saturated chain.
These facilitate cross-linking reactions which do not affect the integrity of the polymer backbone. This feature gives EPDM excellent heat, ozone and chemical resistance. Physical properties are very good and resistance to polar fluids is generally good. Low temperature resistance is very good and EPDM can be compounded to give excellent electrical resistance.
