EPDM rubber is a terpolymer produced by epdm extruders using ethylene, propylene and non-conjugated diene as raw materials. Commercial production began in 1963. Annual consumption worldwide is 800,000 tons. The main feature of EPDM is its superior resistance to oxidation, ozone and erosion. Since EPDM rubber belongs to the polyolefin family, it has excellent vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of fillers and oils without affecting the characteristics. Therefore, a low-cost rubber compound can be produced.
Molecular structure and properties
Tripropylene is a terpolymer of ethylene, propylene, and a non-conjugated diene. Diene has a special structure, and only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as a crosslink. The other unsaturated one will not become the polymer backbone, but only the side chains. The main polymer chains of EPDM are fully... less
