Achrm@ ZnO-80 EPDM Pre-Dispersed Rubber Chemicals Masterbatch

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 a terpolymer of ethylene, propylene and non conjugated dienes. Dienes have a special structure. Only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as the cross chain. The other unsaturated polymer will not become the main chain, but only the side chain. The main polymer chain of EPDM is completely saturated. This property makes EPDM resistant to heat, light, oxygen, especially ozone.
