Silica is applied in the rubber industry:

Reinforcing agent: White carbon black can significantly improve the physical properties of rubber. For example, adding a small amount of white carbon black to ordinary rubber can significantly improve its mechanical strength, wear resistance, and aging resistance. Its application in tire tread rubber and carcass rubber helps to improve tear resistance, adhesion performance between rubber and cord, etc. When producing colored or light colored rubber products, white carbon black can replace carbon black for reinforcement, meeting the color requirements of the product.

Green tire manufacturing: In the production of green tires, white carbon black can reduce the rolling resistance of tires without losing their wet skid resistance, which is of great significance for improving the comprehensive performance of tires.
