EPM rubbers are made up of ethylene and propylene copolymers that develop long saturated molecular chains capable of making the compound suitable for contact with many fluids of different natures. By adding a third monomer to the compound, EPDM rubber is obtained, which presents shorter molecular chains with respect to saturated rubber; the terpolymer obtained adds a good resistance to radiation to the characteristics of the starting copolymers.
