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 0.87. 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 propylene rubber raw rubber prices high, after high filled,physical mechanical degrade is not much,

 2, Aging resistance, ethylene propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor, color stability, electronic, oily and normal temperature liquid filling. Ethylene propylene rubber products under 120 ℃ can be use for a long time,then, under the 150-200 ℃ can be temporary or intermittent use. Join the suitable stabilizer can improve  temperature of use

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 chamical compound,bibulous rate is low,it has good insulating properties
