Polyetherimide (PEI) has a wide range of applications and the market size continues to expand

Polyetherimide (PEI) refers to a super engineering plastic made from amorphous polyetherimide as the base material. Polyetherimide appears as an amber transparent solid. It has the advantages of good heat resistance, UV resistance, high modulus, high strength, good mechanical properties, and wear resistance. It is widely used in electronics, household appliances, medical equipment, aerospace, Widely used in lighting and other fields.

The preparation methods of polyetherimide include melt polycondensation method, direct continuous method, polycyclic condensation polymerization method, polynitro substitution method, etc. The melt polycondensation method refers to mixing a composition containing aromatic diamines and producing finished products through high-temperature melting, polycondensation, powdering, imidization and other processes. This method has the advantages of green environmental protection, low energy consumption, and good quality of finished products. It is The mainstream preparation method of polyetherimide has now achieved industrial production. In the future, as the technological innovation level of local enterprises continues to improve, my country’s polyetherimide industry will gradually develop in a high-quality direction.

Polyetherimide is a super engineering plastic with a wide range of applications, including electronics and electrical, household appliances, medical equipment, aerospace, lighting, etc. In the field of electronics and electrical appliances, polyetherimide can meet the demand for miniaturization of electronic devices, and its end products include printed circuit boards, electrical switches, connectors, etc.; in the field of household appliances, polyetherimide has heat resistance and can be used It is used to produce steam cookers, ovens and other home appliances; in the field of medical equipment, polyetherimide can be used to produce medical monitoring probe shells and other products.

According to the “2023-2028 China Polyetherimide (PEI) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that, benefiting from the growth in downstream demand, the development of the polyetherimide industry has accelerated. The global polyetherimide market size will reach US$670 million in 2022, a year-on-year growth of 5.9%. In terms of the local market, my country’s polyetherimide market penetration rate has been low for a long time due to factors such as high technical barriers. However, in recent years, as the technological maturity of local companies has improved, my country’s polyetherimide market has continued to expand, reaching US$190 million in 2022.

The global polyetherimide market is mainly concentrated in Europe, the United States, Japan and other countries. Representative companies include Solvay of Belgium, RTP of the United States, and Ensinger Engineering Plastics of Germany. ), Japan Baifu Chemical Company, etc. There are a small number of polyetherimide manufacturers in my country, mainly including Youju New Materials, China Chemical Engineering, etc.

Industry analysts said that polyetherimide has the characteristics of good heat resistance, UV resistance and high modulus, and is widely used in many fields. Wide range of applications. In recent years, driven by market demand, the development space of my country’s polyetherimide industry has continued to expand. my country’s polyetherimide industry started late and the product market penetration rate is low. In the future, with technological upgrading and the continuous release of market demand, the scale of my country’s polyetherimide market will further expand.
