EPDM is classified into PM composed of ethylene and propylene copolymer, EPDM composed of terpolymer of ethylene, propylene and non-conjugated diene, Because it has a strong polymer structure, weather resistance and ozone resistance are superior to other synthetic rubbers, so automotive parts, electric/wire insulation coating It is widely used in our daily life, such as materials, building roofing sheets, tire tubes, and general industrial rubber parts.
