Special Synthetic Rubber
Ethylene Propylene Rubber / EPM, EPDM
In comparison with diene type rubbers. EP excels in heat resistance, ozone resistance, weather resistance, in particular, since EP does not have any double bonds in the main chain of the polymer molecule.
Since broad range of Ethylene Content and Mooney Viscosity are prepared, you may select the most suitable product for your application either in plastic modification or in rubber application.
In addition, since it excels in steam resistance, low temperature characteristics, and electrical characteristics, as well as enables high loading of fillers, it is applied broadly to tires, tubes, belts, hoses, water-proof sheets, weatherstrips, electrical wires, various automotive parts, etc.
