Ethylene propylene diene monomer, EPDM, is a type of synthetic rubber elastomer characterized by a wide range of applications. This material is compatible with fireproof hydraulic fluids, ketones, water temperature fluctuations and alkalis. The key properties of EPDM are its outstanding heat, ozone and weather resistance along with excellent electrical insulating properties.
