What is EPDM (Ethylene Propylene Diene Monomer Rubber)?
EPDM (Ethylene Propylene Diene Monomer Rubber) is a group of synthetic elastomers produced from the monomers ethylene, propylene, and a diene. Large-scale production began in 1963 at the former Chemische Werke Hüls. The properties of EPDM depend on the ratio of the three monomers, the degree of cross-linking, and the type of diene used – allowing EPDM to be tailored precisely to specific application requirements, such as EPDM granulate used in flooring panels.
EPDM is employed in a wide range of applications, including high-quality membranes for flat roofs, pond construction, window seals, and as gasket material in vehicles. It is renowned for its excellent resistance to ozone, UV radiation, and ageing. EPDM is temperature-resistant from –60 °C to +160 °C, remains flexible in cold conditions, and is highly resistant to acids, alkalis, alcohols, water (including hot water), chlorine, and hydrochloric acid. However, like SBR, EPDM is not resistant to oils, greases, or petrol, and it offers very good electrical insulation properties.
