my country is a major producer of isocyanates, but demand for specialty isocyanates still depends on imports.

Isocyanate is the general name for various esters of isocyanate. According to the number of groups, isocyanate can be divided into monoisocyanate, diisocyanate and polyisocyanate, among which diisocyanate also includes toluene diisocyanate and diphenylmethane diisocyanate (MDI). , Isophorone diisocyanate, etc. Isocyanate contains unsaturated bonds in its structure and is highly reactive. It is a key raw material for the production of polyurethane.

After years of development and accumulation, my country’s position in the international isocyanate market has continued to improve, and its production capacity of TDI, MDI and other isocyanates ranks first in the world. But despite this, due to limited research and development capabilities, there are still few types of isocyanates in my country with independent intellectual property rights. Products such as PDI and There are still certain gaps in terms of type and performance.

my country is a major producer and exporter of isocyanates in the world. Domestic isocyanates have been exported to the United States, the Netherlands, South Korea and other countries, among which the United States is the main export destination of domestic isocyanates. According to the “2022-2026 China Isocyanate Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, in China On the market, isocyanate manufacturers mainly include Wanhua Chemical, Shanghai Lianheng, Gansu Yinguang, Yantai Juli, Cangzhou Dahua, etc. Among them, Wanhua Chemical is the largest isocyanate manufacturer in the world and one of the few in China with the ability to supply special isocyanates. One of the enterprises.

The isocyanate industry has high entry barriers. In foreign markets, isocyanate manufacturers mainly include Covestro, BASF, Huntsman, Japan’s NPU, Mitsui Chemicals, South Korea’s Kumho, etc. European, American and Japanese companies started early, have advanced technology and strong R&D capabilities, and are in a leading position in the global specialty isocyanate market. Among them, Covestro’s specialty isocyanate supply capacity ranks first in the world.

Under the policy plan, during the “14th Five-Year Plan” period, the structure of my country’s isocyanate industry will continue to be optimized. On the one hand, it will increase R&D and innovation capabilities, reduce consumption indicators and production costs through process technology optimization, or develop low-cost, high-efficiency, green on the other hand, encourage the development and production of special isocyanates and explore new application scenarios of special isocyanates to realize the value extension of the industrial chain.

Industry analysts said that isocyanates are widely used in water-based coatings, film products, synthetic leather, sealants, thermoplastic elastomers and other fields. In the future, with the advancement of isocyanate technology and optimization of performance, the application of isocyanate is expected to expand to optical lenses, electronic substrates, microporous materials and other fields. my country is a major producer of isocyanates, but in terms of special isocyanates, my country’s market demand still relies on imports, and there is broad room for domestic substitution in the future.
