The bismaleimide triazine (BT) resin industry has broad development prospects, and Mitsubishi of Japan is the main global supplier.

Bismaleimide triazine resin, referred to as BT resin, is a resin composed mainly of bismaleimide (BMI) and triazine, and is composed of epoxy resin, polyphenylene ether resin, allyl compounds, etc. A resin that is a modified resin component. BT resin is an important type of high-temperature-resistant thermosetting resin that can be widely used in electronics, automobiles, aviation, electrical insulation and other fields.

BT resin is mainly prepared by copolymerization of cyanate ester resin with -OCN and bismaleimide under high temperature conditions. Bismaleimide is a key raw material for the production of BT resin. At present, my country has Tianyi Chemical, Hengkang New Materials, Boyuan High-tech Materials, Shuangma New Materials, Yanlin New Materials, Hengshen Co., Ltd., Longji Chemical and other companies Lay out its R&D and production areas. In the future, as local companies increase technology research and development, my country’s bismaleimide production capacity will continue to increase, thereby creating favorable conditions for the development of the BT resin industry.

BT resin has the advantages of low thermal expansion rate, low dielectric constant, high Tg point, good heat resistance, good environmental protection, good corrosion resistance, and high tear strength. In the electronic field, it can be used to manufacture BT carrier boards, and then It is used in the production of storage chips, radio frequency chips, and MEMS chips; in the automotive field, it can be used to manufacture engines, braking system components, etc.; in the aviation field, it can be used to manufacture radar antennas, brake linings, high-temperature structural parts, and thermal protection materials. wait.

According to the“2023-2028 Bismaleimide Triazine (BT) Resin Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It shows that in recent years, against the backdrop of rapid development of the downstream market, domestic demand for BT resin has continued to increase. From 2017 to 2022, the scale of domestic BT resin consumption is increasing at a compound annual growth rate of more than 5%, and the industry has broad prospects for development.

BT resin was first developed by Japan’s Mitsubishi Gas Chemical Company in the 1980s. It has patents and commercial mass production capabilities, and occupies a leading position in the global market. At present, the patent period for Mitsubishi Gas BT resin has expired. However, due to high technology, raw material, and customer barriers, it is difficult for other companies to enter the market. Mitsubishi still dominates the global market.

From the perspective of the domestic market, my country’s BT resin industry started late, and currently the main market share is still occupied by Japan’s Mitsubishi Corporation. However, in order to meet the demand for BT carrier boards required for downstream high-performance chips and electronic components, Chinese companies are actively laying out the BT resin research and development track. Major companies include Zhuhai Hongchang Electronic Materials Co., Ltd., Sichuan Lutianhua Innovation Research Institute Co., Ltd., etc. There is still much room for growth in the industry in the future.

Industry analysts said that BT resin is a type of thermosetting resin with excellent performance and can be widely used in automobiles , electronics, aviation and other fields. Among them, electronics is the main application field of BT resin. In this field, it is mainly used to manufacture BT carrier boards. Benefiting from the rapid development of domestic high-tech industries such as the Internet of Things and artificial intelligence, the market demand for BT resin continues to increase. However, at present, my country’s BT resin production strength is weak, and the domestic and global markets are still dominated by the original research company Mitsubishi of Japan. There is broad room for domestic substitution in the domestic market.
