What is EPDM?
May 15, 2018


EPDM stands for Ethylene Propylene Diene Monomer, a synthetic rubber used in a range of applications. EPDM is used most commonly used in the automotive and construction industries for various seals due to its excellent resistance to environmental factors such as Ozone, UV and general weathering. Typical applications of EPDM are window and door seals (glazing), waterproofing sheets and electrical gaskets. However, EPDM has a disadvantage when up against its closest competing elastomer silicone rubber - temperature resistance. When compared with silicone rubber, EPDM has inferior resistance at higher temperatures as it can only reach maximum temperatures of 130°C (266°F).
