China’s thermoplastic polyimide market relies on imports and domestic development is relatively lagging behind

Thermoplastic polyimide (TPI) is a polymer with a chain structure containing imine rings and aromatic rings on the main chain. Thermoplastic polyimide (TPI) has good melting properties and can be processed by conventional plastic molding processes such as molding, extrusion, and injection. No chemical cross-linking occurs during its processing, so it can be melted during melting. Shaped again during processing.

Thermoplastic polyimide (TPI) not only has better thermal stability than other high-temperature-resistant plastics, but also has better performance in mechanical, dielectric properties, tensile toughness and dimensional stability. It can be processed into films, Plates, bars, etc. are used in many cutting-edge scientific and technological fields such as aerospace, electronic appliances, machinery, automobiles, and national defense. The market development prospects are good, and the market demand continues to grow, and the demand growth rate remains at double-digit levels. According to the “China Thermoplastic Polyimide (TPI) Industry Market In-depth Research and Development Prospects Report 2023-2028” released by the Industrial Research Center》, in 2022, China’s thermoplastic polyimide (TPI) market demand will be 514 tons, with a growth rate of 11.8%.

The thermoplastic polyimide (TPI) industry has high technical barriers. Its research first started in leading countries such as the United States and Japan. General Electric Company (GE) of the United States has developed the second generation TPI (Extem), and Mitsui Corporation of Japan has also Semi-crystalline TPI (Aurum) was successfully developed. In contrast, China’s research on thermoplastic polyimide (TPI) started relatively late. At present, only Hangzhou Soumengte Technology Co., Ltd., Changchun Gaoqi Polyimide Materials Co., Ltd., Jiangsu Junhua Special Engineering Plastic Products Co., Ltd., etc. A few companies have production capacity, and there is still a certain gap between the performance indicators of domestic products and similar foreign products. Market demand mainly relies on imports to meet market demand.

As a high-end material, thermoplastic polyimide (TPI) currently has a high product price and is only used in a few industries that have high material performance requirements and low price sensitivity, such as aerospace, military industry and other fields where thermoplastic polyimide is widely used. Although the market capacity of amine (TPI) materials in the automotive, machinery, electronic and electrical industries is large, the actual demand for thermoplastic polyimide (TPI) is relatively limited, and the market has not yet opened. In the future, as the production cost and price of thermoplastic polyimide (TPI) decline, the application of thermoplastic polyimide (TPI) will no longer be limited to high-end fields such as aerospace and military industry, but will gradually expand to automobiles, machinery, Penetrated into civilian electronics and other fields, its market demand is gradually growing.

Although China’s thermoplastic polyimide (TPI) market has huge potential, it is subject to a short development time and weak technology accumulation. The development of China’s thermoplastic polyimide (TPI) industry is relatively lagging behind. The domestic market’s thermoplastic polyimide (TPI) TPI) products are mainly occupied by foreign brands such as Evonik, DuPont, and Mitsui Chemicals, and local products have a small market share. In recent years, due to the US blockade and suppression of domestic high-tech enterprises, domestic downstream enterprises have actively supported the development of local supply chains and gradually begun to consciously promote the localization of supply chains, providing a good foundation for the development of China’s thermoplastic polyimide (TPI) local industry. opportunity.
