Commonly known as white carbon black, it is suitable for reinforcing tires, rubber shoes and other products.
Fine silica is ultra-fine precipitated silica (commonly known as white carbon black) made by special processing technology. It has excellent reinforcement and dispersion. Years of production practice has proved that it can completely or partially replace expensive gas-phase white carbon black and greatly reduce the production cost of customers.
Fine-sil325 is suitable for reinforcing tires, rubber shoes and other products to improve the bending resistance, anti cracking performance and physical properties of products. It can obtain high wear resistance, high strength and transparency. Extend the use effect of the product
