Achrm@ Dptt 75 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.
