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.

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