Polyethersulfone (PES) has excellent comprehensive properties and the industry has entered a mature development stage

Polyethersulfone (PES), also known as polyetherphenyl sulfone, polyphenylene ether sulfone, and polyaryl ether sulfone, is a thermoplastic polymer material with excellent comprehensive properties. Polyethersulfone appears as light yellow to gray-brown granular material with no special odor. It has the characteristics of stable insulation performance, good heat resistance, good dimensional stability, and good hardness. It is widely used in medical equipment, coatings, electronics, automobile manufacturing, and mechanical processing. , lighting and other fields are widely used.

The main preparation methods of polyethersulfone include dehydrochlorination and desalination. The dehydrochlorination method refers to the polycondensation of diphenyl ether and 4,4′-bisulfonyl chloride diphenyl ether, and the dehydrochlorination reaction produces polyethersulfone. This method has the advantages of low production cost and simple operation, but it is easy to cause corrosion to the equipment. ; The desalting method uses 4,4′-dichlorodiphenylsulfone and 4,4′-dihydroxydiphenylsulfone (bisphenol S) sodium salt as the main raw materials, and the finished product is obtained through self-condensation desalting reaction. This method can be used to prepare High-performance polyethersulfone has been produced, but there are problems such as difficulty in purification and complicated processes.

Polyethersulfone, ordinary bisphenol A-type PSF and polyarylsulfone (PAS) are polysulfone derivatives. According to different uses, polyethersulfone can be divided into three types: polyethersulfone films, polyethersulfone profiles and polyethersulfone products. Polyethersulfone products are chemical-resistant, non-toxic and flame-retardant, and are widely used in many fields. In recent years, as the production technology has matured, my country’s polyethersulfone market demand has grown steadily. According to the “2023-2028 China Polyethersulfone (PES) Industry Market In-depth Research and Development Prospects Forecast Report” shows that my country’s polyethersulfone market size will reach 740 million yuan in 2022, a year-on-year increase of 6.1%.

Medical equipment, coatings, electronics, automobile manufacturing, mechanical processing, lighting, etc. are the main application areas of polyethersulfone. In the field of medical equipment, polyethersulfone has the advantage of being resistant to repeated sterilization and can be used to produce syringes, contact lens sterilizers, surgical containers and other products; in the field of automobile manufacturing, polyethersulfone can be used as engine gears and igniter noise eliminators , fog lamp reflectors and other automotive parts; in the field of lighting, polyethersulfone can be used to produce indicator lamp covers, reflectors and other products.

Shandong Haoran Special Plastics Co., Ltd., Guangdong Youju Advanced New Materials Co., Ltd., Chengdu Ouse Medical Equipment Co., Ltd., Changchun Jida Special Plastics Engineering Research Co., Ltd., etc. are the main manufacturers of polyethersulfone in my country. The main business of Youju New Materials is the research and development, production and sales of polyethersulfone and its upstream raw materials. According to the company’s financial report, in the first half of 2022, Youju New Materials’ revenue reached 180 million yuan.

Industry analysts said that at present, my country’s polyethersulfone industry has entered a mature development stage. As a special engineering plastic, it has been widely used in many fields. obtain widespread application. Benefiting from the continuous innovation of production technology by local enterprises, my country’s polyethersulfone production and quality continue to improve. It is expected that companies with high-performance polyethersulfone production capabilities will occupy more market shares in the future.
