Ethylene propylene rubber is a kind of rubber with a lower density of 0.87. In addition, a large amount of oil can be filled and fillers can be added, which can reduce the cost of rubber products and make up for the high price of raw rubber of ethylene propylene rubber. In addition, for ethylene propylene rubber with high Mooney value, the physical and mechanical energy after high filling will not be reduced by much.

EPDM is essentially non-polar, resistant to polar solutions and chemicals, low water absorption, and has good insulation properties. In the production process of ethylene propylene diene monomer, its characteristics can be adjusted by changing the amount of three monomers, ethylene propylene ratio, molecular weight and its distribution, and vulcanization methods.
