EPDM sponge
Machine product rubber with exceptional durability, weather resistance and insulation characteristics
EPDM is a terpolymer consisting of ethylene, propylene and small amounts of diene. The rubber is superior in weather resistance, ozone resistance, heat-resistant aging characteristics, chemical resistance, and low temperatures and is electrically insular. EPDM is used in vehicles, machinery, building engineering, electrical, and as a packing material for the chemical industry.
■ Main applications ： Window frame rubber, automotive parts, seal material, packing material, engineering gaskets, conveyor belts, etc.
