The area where the amount of precipitated silica is large is in the rubber industry as the best white reinforcing filler. It has excellent reinforcing performance and surface activity in white and light-colored fillers. It is widely used in rubber soles, tires, hoses, Tapes, rubber rollers, rubber seals and other products.

In the process of producing rubber products, it is usually necessary to add carbon black to the rubber to improve the strength, abrasion resistance and aging resistance, but the addition of carbon black makes the products all black and low-grade. Using silica as a reinforcing agent and adding a small amount of silica to ordinary rubber, the strength, abrasion resistance and aging resistance of the product can reach or exceed traditional rubber products, and it can produce novel, A new generation of rubber products with excellent performance, such as white carbon black modified rubber materials, and can keep the color unchanged for a long time. The flexural resistance of the colored tire side rubber has been increased from the original 100,000 times to more than 500,000 times and it is expected to realize the colorization of domestic automobile and motorcycle tires in the near future.

Adding white carbon black to polyvinyl chloride, epoxy resin, vinyl resin and other processable resin materials can significantly improve product quality, facilitate processing and molding, improve production efficiency, increase varieties, and expand application scope. After adding white carbon black to the PVC plastic film, it not only improves its transparency, strength, and toughness, but also significantly improves its anti-aging performance. The hardness, roughness and anti-aging performance of plastic doors and windows produced by adding a small amount of white carbon black to ordinary plastic PVC are greatly improved. Using silica to modify plastic polypropylene, the main technical indicators (water absorption, insulation resistance, compression residual deformation, bending strength, etc.) all meet or exceed the performance indicators of engineering plastic nylon 6, which can be made of polypropylene engineering plastics. Parts are used instead of nylon 6, the product cost is greatly reduced, and its economic benefits are very significant.
