EPDM
Jun 20, 2018

Ternary ethylpropylene rubber is a ternary copolymer of ethylene, propylene and non-conjugate diolefin.The world consumes 800,000 tons a year.The main characteristic of EPDM is its superior ability to resist oxidation, ozone and erosion.Because ternary ethylpropylene rubber belongs to the polyene (PA66) hydrocarbon family, it has excellent vulcanization characteristics.Of all rubber, EPDM has the lowest specific gravity.It can absorb a lot of fillers and oil with little effect on properties.So you can make rubber compounds that are cheap.

Molecular structure and properties

Ethylene ternary propylene is a ternary copolymer of ethylene, propylene and non-conjugate diolefins.Diolefins have special structure, only one of the two bonds can copolymerize, and unsaturated double bonds are mainly used as the crosslink.The other unsaturated will not become the aggregation owner chain, only the side chain.The main polymer chain of triethylene - propylene is completely saturated.This makes triethylpropylene resistant to heat, light, oxygen and especially ozone.Ternary ethylene-propylene is essentially non-polar, resistant to polar solutions and chemicals, low water absorption, and good insulation.
