Description
Silphobic 6508 is precipitated silica whose surface is modified with organosilane for application in the rubber industry.
Silphobic 6508 is used as reinforcing filler in rubber compounds. They react with unsaturated polymers during vulcanization under formation of covalent chemical bounds. This imparts greater tensile strength, high moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties.
