EPDM Rubber

EPDM rubber (ethylene propylene diene monomer rubber) is an elastomer which is characterized by wide range of applications. EPDM rubber is used in automotive weather-stripping and seals, glass-run channel, radiator, garden and appliance hose, tubing, washers, belts, electrical insulation,as well as electrical insulation it is also used as a medium for water resistance in high voltage polymeric cable jointing installations, roofing membrane, geomembranes, rubber mechanical goods, plastic impact modification, thermoplastic, vulcanizates, motor oil additive, pond liner, electrical cable-jointing and chainmaille applications.
Satisfactory compatibility with fireproof hydraulic fluids, ketones, hot and cold water, and alkalis. Unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons, halogenated solvents, and concentrated acids.
