In recent years, with the tightening of environmental policies and the rapid development of the new energy vehicle industry, the market demand for high-performance rubber reinforcement material white carbon black (gas-phase silicon dioxide) has continued to rise. As a green alternative to traditional carbon black, white carbon black not only significantly improves the wear resistance and tear resistance of rubber products, but also reduces rolling resistance, becoming a key material for green tire manufacturing.
According to industry data, the global white carbon black market is growing at an average annual rate of 6%, with particularly significant demand growth in the Asia Pacific market. As the world's largest consumer of rubber, China's self-sufficiency rate of white carbon black has exceeded 85%. Recently, several leading companies have announced expansion plans, such as Jiangxi Black Cat Carbon Black Co., Ltd. adding 40000 tons/year of production capacity to further consolidate the stability of the domestic supply chain.
Technological innovation has become a new highlight in the white carbon black industry. Through surface hydroxyl modification technology, the dispersibility of white carbon black is greatly improved, and its application is expanded in high-end sealants, medical silicone and other fields. The "ultrafine structured white carbon black" developed by a certain enterprise has been applied as insulation material for new energy vehicle batteries, helping to improve battery safety.
Environmental advantages accelerate the replacement of traditional materials with white carbon black. Each ton of white carbon black can reduce carbon emissions by about 1.2 tons, which is in line with the "dual carbon" goal. Industry insiders point out that with the increasing penetration rate of green tires and the expansion of emerging fields, the white carbon black industry is expected to usher in a new round of growth, and it is expected that the domestic market size will exceed 5 billion yuan by 2027.
