Silica is widely used as a reinforcing agent in the rubber field, and its amount accounts for 70% of the total. Especially when manufacturing white, colored and light-colored rubber products, white carbon black is more suitable for coloring. For example, the tensile strength of unreinforced silicone rubber does not exceed 0.4 MPa, and the strength can be increased by 40 times after being reinforced by the gas phase method of silica.
