Coupsil® 8113 GR

Coupsil® 8113 GR by Evonik acts as a reinforcing filler in rubber compounds. Offers the advantage of a homogeneous modification with low moisture adsorption during storage and significantly lower development of ethanol during mixing and processing. It reacts with unsaturated polymers during vulcanization under formation of covalent chemical bonds. This imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties. Applications for Coupsil® 8113 GR include low rolling resistant tires with high wet grip and low heat generation, mechanical rubber goods, shoe soles. It has a shelf life of 12 months.
