The rubber industry is one of the largest application areas of white carbon black. White carbon black plays an important reinforcing role in rubber products due to its unique physical and chemical properties, significantly improving the performance and quality of rubber products.

1、 The reinforcing effect of white carbon black
White carbon black has a high specific surface area and excellent dispersibility, which can be uniformly dispersed in the rubber matrix, forming a large number of physical cross-linking points. These cross-linking points can effectively transmit stress, enhance the interaction force between rubber molecules, thereby improving the tensile strength, tear strength, and wear resistance of rubber products. Meanwhile, white carbon black can also improve the processing performance of rubber, enhance the dimensional stability and surface smoothness of products.

2、 Application in tire manufacturing
Tires are one of the most important products in the rubber industry and also the most widely used field for white carbon black. Adding white carbon black to tire tread rubber can significantly improve tire grip and skid resistance, reduce rolling resistance, and enhance fuel economy. In addition, white carbon black can enhance the wear resistance and tear resistance of tires, extending their service life. With the rise of the concept of green tires, the application proportion of white carbon black in environmentally friendly tires is increasing, becoming a key factor driving technological progress in the tire industry.

3、 Application in other rubber products
In addition to tires, white carbon black is also widely used in other rubber products, such as conveyor belts, seals, shoe materials, etc. Adding white carbon black to the conveyor belt can improve its wear resistance and tear resistance, and extend its service life; Adding white carbon black to the seal can enhance its elasticity and oil resistance, and improve the sealing effect; Adding white carbon black to shoe materials can improve the wear resistance and slip resistance of the sole, enhancing wearing comfort.

4、 Summary of Advantages
The application of white carbon black in the rubber industry has significant advantages. It can not only significantly improve the physical and mechanical properties of rubber products, but also improve processing performance and product quality. Meanwhile, as an inorganic filler, white carbon black has the characteristics of non-toxic, odorless, and environmentally friendly, which meets the requirements of modern industry for green and sustainable development. Therefore, the application prospects of white carbon black in the rubber industry are broad, and the market potential is enormous.
