White carbon black, chemically known as silicon dioxide (SiO ₂), plays an indispensable role in industrial fields such as rubber, plastics, coatings, inks, etc. due to its high specific surface area, excellent reinforcement performance, and chemical stability. Although the name contains the word 'black', its actual form is a white powder, which makes it an ideal additive for many material modifications.


In the rubber industry, white carbon black is one of the key raw materials for tire manufacturing. Compared to traditional carbon black, white carbon black can significantly improve the wet grip and wear resistance of tires, while reducing rolling resistance, which helps to save energy and reduce emissions. With the rise of the concept of green tires, the application prospects of white carbon black are becoming increasingly broad. In addition, in the field of plastics, white carbon black can enhance the strength, hardness, and heat resistance of materials, and is widely used in high-end products such as automotive components and electronic and electrical casings.
