Product Description
KEP-281 is a very high Mooney viscosity grade with medium ethylene content, high diene content and long chain branching. Having high molecular weight and unique molecular weight distribution, KE-281F offers enhanced processing characteristics with retaining physical and rheological properties. Because of its excellent collapse resistance, it provides to develop the large and complex body sealing profiles. With combining the smooth extrusion and excellent collapse resistance, it has been primarily designed for auto body sealing profiles without polymer blending. KEP-281F is widely used in weather strip solid profiles (auto body sealings), heat resistant hoses and industrial extruded goods.
