EPDM (ethylene propylene diene monomer [rubber]) – terpolymer obtained from ethylene-propylene-diene monomers. It is an elastomer cross-linked in the process of sulfur or peroxide vulcanization.
EPDM has very good properties, including: resistance to weather conditions (ozone), resistance to water, stability of properties at temperatures up to +110 °C, flexibility at temperatures up to -40 °C
