Silphobic 8113 is a precipitated silica whose surface is modified
with organosilane for application in the rubber industry.
Silphobic 8113 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.
The application areas of Silphobic 8113:
low rolling resistant tires with high wet grip and low heat generation,
mechanical rubber goods, shoe soles.
