Silica in Tyre applications

Silica is one of the most important reinforcing fillers in the rubber industry. As a reinforcing filler, silica provides a unique combination of high tear strength, high modulus and fatigue resistance, particularly low rolling resistance and superior wet traction for 'green' tire tread applications.

Both precipitated silica and fumed silica are used in tyre production.

For tires, silica can significantly improve the physical and mechanical properties of the rubber compound, decrease rolling resistance, and improve safety performance in raining weather.

Adding silia into tire formulation will soften the scratch between rubber molecules,this decreases energy loss and saves vehicle fuel consumption; Besides, as fumed silica is white powder,it’s easy to mix with other colors, giving chance for producing colorful tires.
