Achrm@ TBBS 75 EPDM Pre-Dispersed Rubber Chemicals Masterbatch

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.

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.
