EPDM Rubber: (ethylene propylene diene monomer) is a type of synthetic rubber. It is an elastomer which is characterized by a wide range of applications. EPDM exhibits satisfactory compatibility with fireproof hydraulic fluids, ketones, hot and cold water, and alkalis, and unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons, halogenated solvents and concentrated acids. The main properties of EPDM are its outstanding heat, ozone and weather resistance. It has excellent electrical insulating properties. It has good resistance to ketones, ordinary diluted acids and alkalines.
