The field with large amount of precipitated silica is as the best white reinforcing filler in the rubber industry. It has excellent reinforcing performance and surface activity in white and light colored fillers, and is widely used in rubber soles, tires, rubber 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 material to improve the strength, wear resistance and aging resistance. However, due to the addition of carbon black, the products are black and of low grade. Using white carbon black as a reinforcing agent and adding a small amount of white carbon black to ordinary rubber, the strength, wear resistance and aging resistance of the product can reach or exceed the traditional high-grade rubber products, and a new generation of rubber products with novel and excellent performance can be produced, such as the rubber material modified by white carbon black, and the color can remain unchanged for a long time. The bending resistance of colored tire side rubber is increased from 100000 times to more than 500000 times, and it is expected to realize the colorization of domestic automobile and motorcycle tires in the near future.


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