Precipitated silica (silicon rubber): This product is made of superfine white carbon black masterbatch manufacture of silicone rubber, and high specific surface and low surface of two types, high specific surface area, suitable for high temperature vulcanized silicone rubber (such as: buttons, transparent silicone rubber, high temperature high pressure sealing ring); low the specific surface area, applied to room temperature (such as glass glue, glue sealant etc.)

Precipitated silica (fire grade): This product is suitable for ABC and BC dry powder fire extinguishing agent, modified to prevent subsidence, caking, out of good performance

Precipitated silica (roller level): the product specific surface area can reach 205 to 235, will give the hardness of rubber roller product comparison, 90-95 reached the shore, all kinds of industrial rubber roller (milling roller, printing roller, transmission rollers, special rollers etc.) reinforcing agent

Precipitated silica (granular environment-friendly): This product for particles of environmentally friendly products, powder after granulating machine extruding molding, prevent dust, can effectively disperse in the tire, and is mainly used for radial truck tire industry in


Precipitated silica is rubber reinforcing materials widely used, generally speaking, the precipitated silica (surface treatment, the exception of superfine reinforcing effect of carbon black) is not good, it is a semi reinforcing filler material. Therefore, according to the use of occasions decided to replace the percentage of carbon black. Precipitated silica for tyre rubber products have cars, dump trucks, trucks, tractors, trucks, bicycles, belts, hoses, gaskets, rubber, food processing industry and threshing rollers, rubber shoes and other rubber products are more or less used silica. Add a certain amount in the ordinary tire in silica can improve the service life of the tire. According to the former West Germany company tire formulation research test results show that if it was equipped with 10 ~ 20 phr silica can improve cementing and tear resistance, so that the tire mileage increase, but also enhance the tire grip on the road, in order to facilitate safe driving. China's tire mileage is lower than the international standard, do not use the carbon black is one of the reasons. In addition, due to the carbon black heat, foreign automotive tyre for highway also tend to add white carbon black. On a bicycle tire market at home and abroad are also increasingly diversified, such as tire bead color and flash ring fancy new varieties are used instead of white carbon black carbon black production. In the production of rubber shoes, rubber shoes, boots, people sports shoes, travel shoes, gym shoes, ballet shoes, not only the requirements and requirements of color fastness, beautiful, comfortable and light. Silica has good reinforcing properties, wear resistance, skid resistance and adhesion of the vamp, and is a good light reinforcing material, so in the development of rubber overshoes to provide shoes quality and style plays an important role.
