Achrm@ Zbec 70 EPDM Pre-Dispersed Rubber Chemicals Masterbatch

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.

Epdm plastic is a terpolymer of ethylene, propylene and non conjugated dienes. it began commercial production in 1963. The annual consumption of the world is 800000 tons. The main characteristic of EPDM is its superior oxidation resistance, ozone resistance and corrosion resistance. As EPDM belongs to polyolefin family, it has excellent vulcanization characteristics. Of all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of filler and oil without affecting the characteristics. Therefore, a rubber compound with low cost can be prepared.
