Application areas

Rubber industry
It is one of the most important application areas. Used as a reinforcing agent in rubber, it can significantly improve the strength, wear resistance and tear resistance of rubber. For example, in tire production, white carbon black can partially replace carbon black to improve the tire's wet grip and anti-skid performance, while also reducing rolling resistance and helping to improve the vehicle's fuel economy.
Paint industry
Used as thickener, anti-settling agent and matting agent. Adding silica to the paint can adjust the rheological properties of the paint, prevent pigment settlement, and produce a matte effect on the paint surface. White carbon black is also a good additive for some paint surfaces that require anti-skid or texture.
Toothpaste industry
Used as a friction agent. White carbon black has moderate hardness and will not cause excessive damage to teeth and gums. At the same time, it can effectively clean the dirt on the tooth surface. Its white appearance also meets the aesthetic requirements of toothpaste.
Other areas
It is also widely used in many industries such as plastics, papermaking, ink, adhesives, medicine, and food. In plastics, it can improve the hardness, toughness and wear resistance of plastic products; in papermaking, it can improve the strength and whiteness of paper; in inks, it can improve the rheological properties and printability of inks.

Industry development trends
Increased demand for high-performance products: With the development of science and technology, the demand for silica products with high purity, small particle size, and high specific surface area is increasing. For example, in the fields of high-end rubber products and electronic materials, the demand for fumed silica continues to rise.
Promotion of green production technology: In the context of increasingly stringent environmental protection requirements, companies that produce silica by precipitation method need to continuously improve their processes and reduce the discharge of waste water and waste residue. At the same time, gas phase production is also exploring how to reduce energy consumption and improve energy utilization.
Development of new application fields: In addition to traditional application fields, the application of silica in new energy, new materials and other fields is being continuously explored. For example, it is used as a separator coating material in lithium batteries to improve the safety and performance of the battery.
