Application

ZC-165MP is a highly reinforcing silica which was especially developed for application in low rolling resistant passenger car tire tread compounds, so called Green Tire . With a specific BET surface area, this silica imparts to tread compounds in combination with bifunctional silanes high abrasion resistance combined with excellent rolling resistance and wet traction.

Precipitated Silica is used in Tyre industry to improve the tear resistance of truck and heavy equipment tyres and also to enhance adhesion between the metallic reinforcement and the rubber of radial tyres.
