It can greatly improve the physical properties of the rubber, reduce the hysteresis of the rubber, and reduce the rolling resistance of the tire without losing its wet skid resistance.


 

Application

It can be used as a reinforcing filler for the production of green tires, and can replace carbon black for the tire side, which can significantly increase the tear strength and tear growth resistance of the tire side, and has no obvious effect on the vulcanization time. Ozone aging resistance depends on the amount of antioxidants and white carbon black. Adding white carbon black to the tread can improve the anti-cutting and anti-tearing properties of the tread and reduce the flaking block. The rolling resistance of silica filled compound can be reduced by 30% compared with that of ordinary carbon black filled compound.
