Application

1. High Dispersion Silica with Micro Pearl is a high dispersion, high purity precipitated silica.
2. It 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.
3. More of its outstanding performance is especially in the low rolling resistance of passenger cartires, winter tires, and other applications.
