Abstract: ethylene-propylene rubber rubber industry is an important raw material, can be divided into binary ethylene-propylene, epdm, modified ethylene-propylene and thermoplastic ethylene-propylene rubber. In a single ethylene, propylene olefin copolymerization and called binary ethylene-propylene rubber, With ethylene, propylene and a small amount of acrylic monomer conjugate double copolymerization and epdm. Can pass will ethylene-propylene rubber for brominated, chlorinated, etc, the modification methods for ethylene-propylene rubber modified widely offers many varieties and grade. Furthermore ethylene-propylene rubber with low density filling, aging resistance, corrosion resistance, excellent properties etc in the automotive industry, construction industry, electric and electronic industry, and other fields have a wide range of applications. One epdm rubber seal in China's automotive products has become the main materials, in its development and application has wide prospect of production process route ethylene-propylene rubber industry has solution polymerization, suspension polymerization, and meteorological polycondensation three, this paper introduces the technical conditions respectively, technical : ethylene-propylene rubber, epdm rubber, rubber seal, modification
