The market development prospects of tetrabutyltin are good and my country’s production capacity still needs to be continuously improved.

Tetrabutyltin is an organic compound with the chemical formula C16H36Sn. It appears as a colorless liquid, is insoluble in water, and is soluble in most organic solvents. There are various production methods for tetrabutyltin, mainly including Grignard reagent method (Grignard method), alkyl aluminum method, Wu’s method, direct method, etc. Among them, the commonly used method for industrial production of tetrabutyltin is the Grignard method, which refers to the method of using tin tetrachloride as raw material and generating tetrabutyltin through chemical reaction.

According to the “China Tetrabutyl Tin Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center, Tetrabutyltin is an important organic chemical intermediate. Its downstream products include organotin heat stabilizers, synthetic plasticizers, organotin catalysts, gasoline anti-explosion agents, ink additives, pesticides and insecticides, broad-spectrum disinfectants, etc. End applications The fields include pesticides, chemicals, petroleum, plastics, medicine, etc.

Among them, heat stabilizer is the main downstream product of tetrabutyltin. Tetrabutyltin has the advantages of good stability, strong weather resistance, high transparency, etc., and has good compatibility with PVC (polyvinyl chloride). Therefore, tetrabutyltin is mainly used as a stabilizer. In PVC product production scenarios, such as PVC pipes, PVC hard sheets, etc.

PVC is one of the five general-purpose resins. It has been widely used in pipes and fittings, shoe materials, profile doors and windows, building materials, cable materials and other fields. The domestic PVC market size in 2022 will be approximately 192.58 billion yuan, a year-on-year increase of 20.8%. In recent years, driven by the rapid development of the domestic PVC market, the market demand for tetrabutyltin has continued to increase and production has continued to increase, and the industry has shown good development prospects. In addition to PVC heat stabilizers, tetrabutyltin also has broad development prospects in the field of antifouling coatings. When used as a marine antifouling coating, tetrabutyltin can reduce the film material of water, thus ensuring the normal operation of the ship hull.

Domestic tetrabutyltin production companies mainly include Yunnan Tin Chemical Materials, Hangzhou Ruike Chemical, Jiangsu Nantong Adwang Chemical, Shanghai Shisihewei Chemical, Jinan Lanxess New Materials, etc. Among them, Yunnan Tin Industry Tin Chemical Materials is the core supplier of tetrabutyltin in China and the only company in the world with the most complete range of tin chemicals. The company’s current annual production capacity of tetrabutyltin has reached 1,400 tons. In the future, domestic production of tetrabutyltin will continue to increase as local companies accelerate their technological advancement.

Industry analysts said that tetrabutyltin is an important organic chemical intermediate, and its downstream applications involve pesticides , chemical industry, petroleum, plastics, medicine, coatings and other fields, the demand space is relatively broad. After continuous research and development in recent years, many companies in my country have entered the tetrabutyltin market. At the same time, an industry-leading company, Yunnan Tin Industry Tin Chemical Materials, has emerged. But overall, my country’s tetrabutyltin production capacity is still relatively low, and local companies need to speed up their technological improvement in the future.
