Si 266® is a bifunctional, sulfur-containing organosilane for rubber applications in combination with white fillers containing silanol groups. Description: Si 266® reacts with silanol groups of white fillers during mixing and with the polymer during vulcanization under formation of covalent chemical bonds. Si 266® imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties. The product is also available as a dry blend (1:1) with carbon black, named X 266-S®. Application fields are: Low rolling resistance tires Information provided by Evonik |
