Application:
Rubber
Silica applied in tapes, rubber covered rollers, rubber tubes and rubber boards etc. can improve their wear resistance, and promote the wetting degree of rubber & fabric which contributes to rubber dispersion and penetration.
Tyre/Tire
Silica in tires can increase the wet skid & wear resistance and reduce the rolling resistance. It can improve the adhesion between rubber and steel-cord. Also it can promote the durability, flexing resistance and shock resistance of rubber.
