The modified polyimide (MPI) market continues to expand, with overseas companies dominating the global market

​​​​ Polyimide refers to a type of polymer containing an imide ring (-CO-NR-CO-) on the main chain, and is an organic polymer material. Modified polyimide (MPI) refers to a material made by modifying polyimide, which can be divided into three types: polyesterimide, polyetherimide and polyamideimide. Modified polyimide has the advantages of wear resistance, high strength, and good heat resistance, and is widely used in film products, synthetic fibers, medical and health, mechanical processing and other fields.

​​ ​​Polyetherimide (PEI) is a subdivided product of modified polyimide and is an amorphous thermoplastic polyimide. Polyetherimide has excellent performance and has broad application prospects in many fields such as aerospace, electronics and electrical. In recent years, with the improvement of the technical level of local enterprises, the localization process of polyetherimide has accelerated, which provides favorable conditions for the development of my country’s modified polyimide industry.

Modified polyimide has a wide range of applications. Among film products, MPI film has the advantages of low dielectric loss and low dielectric constant, and can be used to produce 5G mobile phone covers, circuit boards, antennas, etc. As the commercialization of 5G accelerates, the market demand for MPI films is increasingly strong, driving the prosperity of the modified polyimide industry to continue to increase. According to the “2023-2028 China Modified Polyimide (MPI) Industry Market In-depth Research and Development Prospects Forecast Report” shows that the global modified polyimide market size will reach US$1.97 billion in 2022, a year-on-year increase of 18.7%.

The global modified polyimide market is concentrated in the United States, Germany, Japan, Taiwan and South Korea. Ube Industrial Co., Ltd. (Ube), Mitsubishi Chemical, Kaneka, Toray, DuPont, and PI Advanced Materials of South Korea The company (PI Advanced Materials), German BASF AG (BASF), Taiwan Nanya Plastics Industry Co., Ltd., etc. are the world’s leading modified polyimide companies, and the above companies account for nearly 80% of the global market share.

Restricted by factors such as high technical barriers, my country’s modified polyimide market is dominated by overseas companies, and local companies lack competitive advantages. Shenzhen Ruihuatai Thin Film Technology Co., Ltd., Beijing Bayi Spacetime LCD Technology Co., Ltd., Electric Connection Technology Co., Ltd., Wuxi Shunxuan New Materials Co., Ltd., etc. are the main manufacturers of modified polyimide in my country. 800 million Spacetime is a representative enterprise of OLED materials and hybrid liquid crystal materials in my country. The company is currently accelerating the research and development and production of modified polyimide for 5G.

Industry analysts said that modified polyimide has good application prospects in the film field. With the acceleration of 5G commercialization, its Market demand will grow further. Polyetherimide (PEI) is a representative product of modified polyimide. As its localization process accelerates, the development trend of my country’s modified polyimide industry will continue to improve.
