| X 50-S® is a blend of the bifunctional, sulfur-containing organosilane Si® 69 and N 330 type carbon black in the ratio 1:1 by weight. The product is applied in the rubber industry in combination with white fillers containing silanol groups. Properties and applications: X 50-S® was developed for customers who prefer to handle Si 96® in a solid version. The Si 96® in the X 50-S® reacts with silanol groups of white fillers during mixing and with the polymer 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. X 50-S® is used in a variety of rubber products where silanol groups-containing white fillers are used and where optimum technical properties are required. Application fields are: Low rolling resistance tires, Mechanical rubber goods, Shoe soles Information provided by Evonik |
