Advsil® Precipitated Silica Sealant Grade

Chemical name: SILICON DIOXIDE
Molecular formula: SiO2 * nH2O
Chemical structure: O=Si=O


A high dispersion, high purity precipitated silica. Can significantly improve the wear resistance of the rubber compound, resistant to flexion performance, heating oxidation, instead of a large number of carbon black for high-performance tires, which can effectively reduce tire rolling resistance and reduce fuel consumption and improve the wet skid resistance and safety performance.

Application:
It was used as active reinforcing filler agent, flow agent, for sealants. With high specific surface area and fine particle size.
