Our high-quality Food Grade Precipitated Silica Iota Fine White Carbon Black is engineered to significantly enhance the physical properties of rubber. It effectively reduces the hysteresis of rubber and diminishes the rolling resistance of tires, all while maintaining excellent wet skid resistance.

 

 

Application

This versatile product serves as a superior reinforcing filler for green tire production, offering an exceptional alternative to carbon black for tire sidewalls. It dramatically boosts the tear strength and tear growth resistance of the tire side without notably affecting vulcanization time. Ozone aging resistance is optimized with the right balance of antioxidants and white carbon black. Adding our premium white carbon black to tire treads enhances their anti-cutting and anti-tearing capabilities while reducing flaking. It also lowers the rolling resistance of silica-filled compounds by 30% compared to standard carbon black-filled compounds.

 

Workshop

Our state-of-the-art workshop boasts hundreds of skilled employees and 18 advanced production lines. Equipped with sophisticated machinery and cutting-edge production technology, every stage from ingredient mixing to final product dispatch is automatically controlled by a DOS system.
