The toluene diisocyanate (TDI) industry is operating at a high level due to continued favorable conditions in the upstream and downstream of the industrial chain.

Toluene diisocyanate, referred to as TDI, refers to a type of organic compound with a benzene ring. It appears as a colorless to light yellow liquid at room temperature and has a pungent odor. There are currently many production processes for toluene diisocyanate, including dimethyl carbonate method, amine phosgenation method, nitro compound carbonylation method, etc. Among them, the amine phosgenation method is currently the mainstream production process for preparing toluene diisocyanate. This method refers to the process of using carbon monoxide, chlorine, toluene, nitric acid, etc. as raw materials, to generate toluene diisocyanate through chemical reaction, drying, purification and other links.

Toluene is one of the main raw materials of toluene diisocyanate. Its domestic production capacity is currently growing rapidly. In 2022, domestic toluene production capacity will reach 26.458 million tons, a year-on-year increase of 27.5%. The sufficient supply of upstream raw materials has laid a good foundation for the continuous improvement of my country’s toluene diisocyanate production capacity. In 2022, the domestic annual production capacity of toluene diisocyanate will reach 1.45 million tons/year.

Toluene diisocyanate is mainly used to make polyurethane resin and is one of the basic raw materials of polyurethane resin. Polyurethane is a type of polymer compound that can be used as polyurethane soft foam, coatings, elastomers, adhesives and other materials in furniture, building materials, construction, automobiles, machinery, packaging, electronics, transportation, home appliances and other fields. Currently, driven by the rapid development of the national economy, polyurethane, as a basic chemical raw material, has continued to develop and expand its application fields, which in turn has driven the increasing market demand for toluene diisocyanate.

The rapid development of downstream application fields has brought broad demand space to the domestic toluene diisocyanate market. According to the “China Toluene Diisocyanate Industry Competition Landscape and Main Competitors Analysis Report 2023-2028” released by the Industrial Research Center It shows that the domestic toluene diisocyanate market demand in 2022 will be approximately 984,000 tons, a year-on-year increase of 5.4%. At present, the development of the domestic toluene diisocyanate industry is continuously favored by the upstream and downstream industry chains, and the industry maintains a high-prosperity trend.

At present, global toluene diisocyanate production capacity is mainly concentrated in North America, Japan, Europe and other countries and regions. Leading foreign companies such as BASF, Bayer, Huntsman, Dow Chemical, and Mitsui Chemicals dominate the global market, and the industry concentration is high. . However, in recent years, driven by the rapid development of the domestic economy, local companies have continued to rise, and my country has gradually become the world’s major producer and consumer of toluene diisocyanate.

Industry analysts According to sources, domestic toluene diisocyanate companies mainly include Wanhua Chemical, Covestro, Yantai Juli, Cangzhou Dahua, Gansu Yinguang, Southeast Electrochemical, Lianshi Chemical, etc. In 2022, due to factors such as the shutdown of production equipment of various enterprises for maintenance, nearly 30% of domestic toluene diisocyanate production capacity is currently unavailable, and market supply and demand are in short supply. Currently, under the influence of the imbalance between domestic supply and demand of toluene diisocyanate, domestic TDI prices continue to rise, and the industry is operating at a high level.
