The use of silica is very versatile and different products have different uses. It is used as a good reinforcing agent for synthetic rubber. Its reinforcing performance is second only to carbon black. Even if it is ultra-fine and proper surface treatment, it is even better than carbon black.

The addition of white carbon black to the resin improves the moisture resistance and insulation properties of the resin. Filled in plastic products, it can increase the slip resistance and oil resistance. Filled in silicone resin, it can be made into plastics with resistance above 200 °C.

Silica can be used as a filler in plastics such as polyethylene, polypropylene, polybutylene, epoxy resin, etc., which can improve the elastic strength and wear resistance of plastics, as well as the thermal stability of hardness. The use of silica for cables can also improve the electrical insulation of cables. For example, methyl vinyl silicone rubber high-voltage wires require gas-phase silica or high-quality precipitated silica. It is often difficult to separate between two layers of plastic film. When the bag is difficult to open when bagging, white carbon black is a very popular opening agent.

Due to the high heat of carbon black hair, automobile tires used in highways abroad tend to add white carbon black. At present, the requirements of bicycle tires in the domestic and international markets are increasingly diversified. For example, new fancy varieties such as tire bead colorization and flashing rings are produced by replacing carbon black with white carbon black.
