Application of silica in rubber industry
Rubber is an elastomer with excellent flexibility, but its comprehensive performance is not satisfactory. It is usually necessary to add carbon black to the rubber in the process of producing rubber products to improve the strength, wear resistance and aging resistance. However, due to carbon The addition of black makes the products all black, and the grade is not high. The advent of silica in my country has laid a material foundation for the production of a new generation of rubber products with novel colors and excellent performance. After adding a small amount of silica to ordinary rubber, the strength, abrasion resistance and aging resistance of the product can reach or exceed high-grade rubber products, and the color can remain unchanged for a long time.
