PI/PMI foam has excellent comprehensive properties and good future application prospects

PI/PMI structural foam material is a structural foam core material based on PI (polyimide) and PMI (polymethacrylimide), which is an advanced functional material. PI/PMI foam has the excellent properties of both PI foam and PMI foam, such as high temperature resistance, good wave transmittance, high specific strength, excellent electrical insulation, good photosensitivity, and environmental protection. PI/PMI foam is a new type of high-end foam core material and an excellent substitute for honeycomb core material and PET foam. Under the background of increasingly strict environmental protection supervision and consumption upgrading, the PI/PMI foam market has broad development space.

According to the “2022-2027 China PI/PMI Foam Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , PI/PMI foam is mainly used as a composite sandwich material. As the most excellent structural foam core material at present, the downstream applications of PI/PMI foam involve aerospace, medical equipment, electronic communications, military industry, automobiles, wind turbine blades, ships , sporting goods and other fields. At present, PI/PMI foam is mainly used in the military field. In the future, as the application expands to the civilian field, the PI/PMI foam industry may usher in a period of rapid development.

At present, the main markets for global PI/PMI bubbles are located in Germany, the United States, Japan and other countries. PI/PMI foam was first researched and developed by NASA, and carried out production, application and promotion. Later, attracted by the market prospects, companies such as Sordal, DuPont, Evonik, and InspectFoam also actively deployed in the market and launched corresponding products. Against the background of high-quality development of the manufacturing industry, lightweight development of automobiles, and accelerated warship construction, the application prospects of PI/PMI foam are promising.

my country’s PI/PMI foam industry started late. Limited by technology, raw materials and other factors, the scale of PI/PMI foam production is small and the products are highly dependent on imports. At this stage, the domestic PI/PMI foam market is still a blue ocean market. New materials are one of the key industries supported by my country’s policies. PI/PMI foam, as a new lightweight sandwich material, has also received strong support from the government. Relevant domestic research institutions include the Ningbo Institute of Materials, Chinese Academy of Sciences, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, and Shanghai Synthetic Resin Research Institute. wait.

Relying on the technology patents of the institute, my country’s PI/PMI foam localization and industrialization process has accelerated. In terms of PI foam, domestic suppliers include Ruihuatai, Kangda New Materials, Qingdao Ocean, etc., and in terms of PMI foam, domestic suppliers include Hunan Zhaoheng Materials, Zhongke Hengtai, Baoding Meiwo, Haobo Technology, etc. With technological advancement, the scale of my country’s PI/PMI foam industry is constantly expanding, and there is broad room for market development in the future.

Industry analysts said that as a composite sandwich material, PI/PMI foam has excellent comprehensive properties and is widely used in automobile lightweighting and military industry. Under the trend of modern development, the application prospects of PI/PMI foam are promising. However, at present, due to limitations of raw materials, technology and other factors, the application scale of PI/PMI foam in my country is still small, and most of it is concentrated in the military industry, while the civilian field needs further development.
