Si 264™

Si 264™ by Evonik is a bifunctional, sulfur-containing Organo silane in combination with white fillers containing silanol groups. It reacts with silanol groups of white fillers during mixing and with the polymer during vulcanization under the formation of covalent chemical bonds. It is used in a variety of rubber products where optimum technical properties are required. It imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties. It is suitable for mechanical rubber goods and shoe soles. In comparison to polysulfide silanes, it leads to lower compression set values and better abrasion resistance. Si 264™ has a shelf life of 24 months.
