EPDM

EPDM (Ethylene Propylene Diene Monomer)

EPDM, commonly known as ethylene-propylene rubber, is an olefinic thermoplastic elastomer with good temperature performance and good compression and tensile set. This elastomer has good abrasion and tear resistance while offering excellent chemical resistance to a variety of acids, alkalines, alcohols and oxidizing chemicals. However, it is susceptible to attack by oils. The maximum service temperature of EPDM is 250°F (121°C). EPDM has a low specific gravity, usually 0.8 to 1.0, and consequently offers low part weight.
