Polypyromellitic imide (PMMI) has a wide range of applications and overseas companies dominate the global market

Polypyromellitimide (PMMI), also known as general-purpose polyimide, is a special engineering plastic. PMMI appears as a white powder and has the characteristics of good electrical insulation properties, high water absorption rate, high obturator rate, and good heat resistance. It is widely used in aerospace, automobile manufacturing, electromechanical equipment, display devices, electronic and electrical fields, etc.

PMMI is a subdivision product of polyimide (PI). Polyimide is an organic polymer material with excellent properties and has broad application prospects in many fields. my country is one of the world’s major consumers of polyimide. In 2022, my country’s demand for polyimide films will reach nearly 20,000 tons. Benefiting from the accelerated development of the polyimide industry, my country’s PMMI market prospects continue to improve.

Coatings, plastics, fibers and films are PMMI end products. PMMI coating has electrical insulation properties and can be used in the processing of metal materials, cable materials and other products; PMMI plastic is a heat-resistant plastic that can be used to produce heat insulation materials; PMMI fiber can be used to separate mixed gases; PMMI film is a representative product of PMMI. It is made by co-extrusion method and has excellent comprehensive performance. It is widely used in display panels, packaging materials and other fields. In the future, as the application scope of PMMI films continues to expand, the prosperity of the PMMI industry will further increase.

According to the “2023-2028 China Polypyromellitic Imide (PMMI) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center >》shows that PMMI is widely used in aerospace, automobile manufacturing, electromechanical equipment, display devices, electronics and other fields. In the field of aerospace, PMMI can be used to produce aviation seals, aviation cables, rocket adhesives, aircraft seat cushions, jet engine parts, etc.; in the field of automobile manufacturing, PMMI can be used to produce automobile connectors; in the field of electromechanical equipment, PMMI It can be used to produce blower impellers, diamond grinding wheels, valve parts, mechanical seals, etc.; in the field of display devices, PMMI can be used to produce liquid crystal orientation films.

The major global PMMI manufacturers include DuPont of the United States, Toray of Japan, KANEKA of Japan, etc. DuPont of the United States is the first company in the world to lay out PMMI R&D and production tracks, and its product sales rank first in the world. Compared with overseas developed countries, my country’s PMMI industry started late. Attracted by market prospects, my country’s R&D enthusiasm continues to rise, and local companies already have a number of invention patents. However, currently, due to factors such as high technical barriers and high production costs, my country’s PMMI output is still unable to meet downstream demand, and the product is highly dependent on imports.

Industry analysts said that PMMI has excellent performance and a wide range of applications. In the future, as market demand is gradually released, the development trend of the industry will continue to improve. . my country’s PMMI industry started late and its demand is highly dependent on imports. In the future, as local companies improve their independent research and development capabilities, the localization process of my country’s PMMI market will accelerate.
