In tire manufacturing, white carbon black has significant advantages as a reinforcing agent, which are mainly reflected in the following aspects:

1. Improving the overall performance of tires
White carbon black can effectively improve the overall performance of tires, especially in the production of high-performance tires such as off-road tires, engineering tires and radial tires. By adding white carbon black, the rolling resistance of the tire can be significantly reduced, thereby saving fuel consumption, while greatly improving the anti-skid and safety performance of the tire. Studies have shown that the use of white carbon black instead of carbon black can effectively reduce the Paine effect of the rubber and the loss tangent value at high temperature, thereby optimizing the rolling performance of the tire. The use of all-white carbon black tread rubber can reduce the rolling resistance by 20% and the tread hysteresis performance by about 50%, thereby saving more than 3% of fuel.

2. Meet special color requirements
Another important advantage of white carbon black in tire manufacturing is that it can meet the reinforcement needs of white, light-colored or colored rubber products. Compared with carbon black, silica does not make the tire black, so it can be widely used in tire products that require special color effects.

3. Improve tire wear resistance and wet traction
After incorporating silica into the tire tread rubber formula, all kinds of tire performance are significantly improved, especially in the balance of wear resistance, wet traction and rolling resistance. The addition of silica enables the tire to have good anti-slip performance while maintaining low rolling resistance, thereby improving the driving safety of the tire on wet and slippery roads.

4. Environmental protection and sustainability
As an environmentally friendly and excellent additive, the application of silica in tire manufacturing is also in line with the current trend of environmental protection and sustainable development. It is non-toxic, odorless, easy to color, and does not produce harmful substances during the production process, which is harmless to the environment and human health.

However, it should be noted that the application of silica in tire manufacturing also has some challenges, such as poor affinity with rubber, easy agglomeration, and possible delayed vulcanization reaction. Therefore, tire manufacturers need to take corresponding measures to optimize the application effect when using silica, such as using modifiers (such as silane coupling agents) to improve the bonding performance between silica and rubber.

In summary, silica has many advantages as a reinforcing agent in tire manufacturing, which makes silica widely used and recognized in the tire industry.
