| Si 264TM is a bifunctional, sulfur-containing organosilane for rubber applications in combination with white fillers containing silanol groups. Description: Si 264TM 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. Si 264TM is used in a variety of rubber products where silanol group-containing white fillers are used and where optimum technical properties are required. Compared to polysulfidic silanes Si 264TM leads to lower compression set values and better abrasion resistance. Application fields are: Mechanical rubber goods, shoe soles Information provided by Evonik |
