Ethylene propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical performance, oil filling and room temperature fluidity. Ethylene propylene rubber products can be used for a long time at 120 ℃, and can be used briefly or intermittently at 150 - 200 ℃. The use temperature can be increased by adding appropriate antioxidant.

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.
