EPDM
Epdm is ethylene, propylene and the terpolymer of conjugated dienes
Low density and high filled ethylene propylene rubber is a rubber,that its density is lower,only 0.*7. Combined with the filling agent, can be added a large number of oil charge and thus can reduce the cost of rubber products, made up  the shortcoming of ethylene propene  rubber raw rubber prices high, after high filled,physical mechanical degrade is not much,
The main polymer chain epdm is completely saturated .This feature makes the epdm can resist heat and light,oxygen,especially ozone.Epdm is non-polarity in essence ,It has resistant to polarity solution and chemical compound,bibulous rate is low,it has good insulating properties
