Silica has a wide range of uses, and different products have different uses. As a good reinforcing agent for synthetic rubber, its reinforcing performance is second only to that of carbon black, and even better than that of carbon black after superrefinement and proper surface treatment. Especially for white, color and light colored rubber products. Used as thickener or thickener, synthetic oil, insulating paint mixing agent, paint fading agent, electronic components of the thixotropic materials, fluorescent screen coating phosphor precipitant, color printing rubber board filling agent, casting release agent. Add into the resin, can improve the moisture resistance and insulation performance of the resin. Filled in plastic products, can increase resistance to slip and oil. Filled with silicone, it can be made into plastic resistant to 200℃ or more. In the paper industry as a filler and paper surface ingredients.

Precipitated silica is a widely used rubber reinforcing material. Generally speaking, because the reinforcing effect of precipitated silica (ultrafine, except for surface treatment) is not as good as carbon black, it belongs to the semi-reinforcing filler material. Therefore, the percentage of carbon black should be replaced according to the application situation. Precipitate silica is used in rubber products of cars, dump trucks, trucks, tractors, forklifts, bicycles and other inner and outer tires, industrial belts, hose, gaskets, rubber plates, grain processing cots, rubber shoes and other rubber industrial products are more or less to use silica. Adding a certain amount of white carbon black into ordinary tires can prolong the service life of tires. According to the original West Germany a company tire formula research test results show that if you can add 10 ~ 20 pieces of white carbon black can improve bonding and tear resistance, so that the tire mileage increases, but also can enhance the tire to the road surface grasp, in order to facilitate safe driving. China's tire mileage is lower than the international level, not using white carbon black is one of the reasons. In addition, because of the high calorific value of carbon black, foreign car tires used for highways also tend to add silica. At present, the requirements of the domestic and foreign markets for bicycle tires are increasingly diversified, such as colorful tire rim and flash ring and other fancy new varieties, are produced with white carbon black instead of carbon black. In the production of rubber shoes, people on rubber shoes, rain boots, sports shoes, travel shoes, fitness shoes, ballet shoes, not only the requirements of fastness, and tonal beautiful, comfortable and light. White carbon black not only has good reinforcing property, wear resistance, skid resistance and vamp adhesion, but also is a good light color reinforcing material, so it plays an important role in providing quality and style of shoes in the development of rubber shoes.

Silica in polyethylene, polypropylene, polybutene, epoxy resin and other plastics can be used as filler materials, can improve the elastic strength and wear resistance of plastics, as well as the thermal stability of hardness. Used for cable can also improve the electrical insulation of the cable, such as methyl vinyl silicone rubber high voltage line will use gas phase silica or high quality precipitated silica. In the two layers of plastic film is often not easy to separate, bag mouth is difficult to open, then white carbon black is a very useful opening agent. When PVC as home flooring materials, if the addition of a certain amount of white carbon black, it can improve the product hardness, elasticity, thermal denaturation and other properties.
