The bismaleimide resin (BMI) market has broad development space and a large number of companies with global presence.

Bismaleimide resin, referred to as BMI, refers to a bifunctional compound containing active end groups in its molecular structure. It is a type derived from the polyimide resin system. Bismaleimide resin appears as yellow crystals, is soluble in strong polar solvents such as dimethylformamide (DMF) and N-methylpyrrolidone (NMP), and is insoluble in common organic solvents such as acetone, ethanol, and chloroform. .

Bismaleimide resin has the advantages of good heat resistance, excellent flame retardancy, strong electrical insulation, high wave transmittance, good radiation resistance, strong corrosion resistance, and good dimensional stability. It is widely used in automobiles, machinery, There are broad application prospects in high-tech fields such as electronics, communications, electricity, computers, aerospace, and national defense.

But at the same time, bismaleimide resin also has the defect of brittleness. Therefore, in order to increase the toughness of bismaleimide resin, it needs to be modified. At present, the mainstream technical route for modifying bismaleimide resin is to reduce the chain rigidity or the cross-linking density of the cured product. Common methods include thermoplastic resin modified BMI, polyamine modified BMI, epoxy resin modified BMI, rubber modified Sexual BMI, allyl compound modified BMI, etc. The modified bismaleimide resin has excellent moisture and heat resistance and has a wider range of applications.

According to the “China Bismaleimide (BMI) Resin Market Feasibility Research Report 2023-2028” released by the Industrial Research Center It shows that currently, driven by the rapid development of the downstream market, the market demand for bismaleimide resin is increasing and the scale continues to expand. The global bismaleimide resin market size will be approximately US$190 million in 2022, a year-on-year growth of 3.8%.

The technical threshold for bismaleimide resin is relatively high. Globally, companies in this field mainly include Evonik of Germany, Mitsubishi Rayon of Japan, Teijin of Japan, Solvay Group of Belgium, Huntsman of the United States, Hexcel of the United States and other international companies. Enterprises as well as Qinyang Tianyi Chemical, Honghu Shuangma New Material Technology, Sichuan Yanlin New Material Technology, Suzhou Hengkang New Material, Tianjin Boyuan High-tech Material, Jiangsu Hengshen Co., Ltd., Henan Longji Chemical, Weihai Guangwei Composite Materials and other Chinese companies enterprise. As companies from various countries increase their research efforts on BMI, it is expected that more mature BMIs will be developed in the future, thereby promoting the continuous expansion of industry development space.

Industry analysts said that bismaleimide resin is a thermosetting resin with heat resistance. It has excellent characteristics of resistance, flame retardancy and electrical insulation, and is widely used in aviation, electronics, military industry, communications and other fields. At present, many companies around the world have deployed in the field of bismaleimide resin. In the future, as companies continue to improve their technical level and increase their research and development efforts, the application space of BMI will continue to expand, and the market shows good development prospects.
