Ethylene propylene rubber (EPM\EPDM) is a copolymer of ethylene and propylene, generally divided into two yuan ethylene propylene rubber and three yuan ethylene propylene rubber. It is characterized by excellent ozone resistance, ultraviolet resistance, weather resistance and aging resistance, ranking first in general rubber. Electrical insulation, chemical resistance, impact elasticity, acid and alkali resistance, low specific gravity, high filling compounding is possible. Heat resistance up to 150°C, resistance to polar solvents-ketones, esters, etc., but not to aliphatic and aromatic hydrocarbons. Other physical and mechanical properties are slightly inferior to natural rubber and superior to styrene butadiene rubber. The disadvantage is that the self-adhesiveness and mutual adhesion are very poor, and it is not easy to bond. Operating temperature range: about -50℃~+150℃.
Mainly used as chemical equipment lining, wire and cable sheathing, steam hose, heat-resistant conveyor belt, automobile rubber products and other industrial products.
