As a thermoplastic engineering plastic, polysulfone (PSF) has a wide range of applications

​ ​ ​ Polysulfone (PSF) is a kind of thermoplastic engineering plastic. Its molecular main chain contains sulfone groups and aromatic nuclei. It is an amorphous non-crystalline polymer material. Polysulfone appears as slightly amber transparent or translucent particles. It has the characteristics of high rigidity, good mechanical properties, good chemical stability, high strength, wear resistance, and corrosion resistance. It is widely used in many fields.

In terms of market segments, according to different synthetic monomers, polysulfone is generally divided into three types: polyethersulfone (PES), ordinary bisphenol A-type PSF and polyarylsulfone (PAS). Polyethersulfone has higher rigidity and heat resistance and is widely used in many fields. At present, my country’s polyethersulfone industry has entered a mature development stage, and market demand is showing a steady growth trend. In 2021, my country’s polyethersulfone market size will reach 670 million yuan, a year-on-year increase of 5.7%. The market share of polyarylsulfone is relatively low, and there are few manufacturing companies in my country. Benefiting from the development of the electronic and electrical industry in the direction of lightweighting, the market demand for ordinary bisphenol A-type PSF continues to grow.

Aerospace, electronics and electrical, food processing, medical equipment and automobile manufacturing are the main application areas of polysulfone. In the field of medical devices, polysulfone can be used to produce artificial dentures, artificial heart valves, syringes, artificial respirators, etc. In the aerospace field, polysulfone is mixed with cyanate ester resin to produce high-toughness structural composite materials with excellent heat and moisture resistance and dielectric properties, which are widely used in the manufacturing of aircraft engine casings. In the field of food processing, polysulfone is an important raw material for food processing equipment such as coffee machines, coffee filters, and steam cookers. As the prosperity of the polysulfone industry continues to improve, its market size continues to expand. According to the “2022 Global Polysulfone (PSF) Industry Market Status Research Report released by the Industrial Research Center, the global polysulfone (PSF) industry in 2021 will The sulfone market size reached US$1.89 billion, a year-on-year increase of 4.7%.

In the global market, major polysulfone manufacturers include Japan’s Sumitomo, Russia’s Shevchink Plant, Germany’s BASF, India’s Garmai Chemicals, and Belgium’s Solvay. BASF and Solvay occupy the major shares of the global polysulfone market. In terms of the local market, my country’s polysulfone market has long been monopolized by overseas brands. Local companies mainly produce mid- to low-end products, and homogeneous competition is fierce. Tianjin Yanjin Technology Co., Ltd., Changchun Jida Special Plastics Engineering Research Co., Ltd. and Shandong Jinlan Special Polymer Co., Ltd. are enterprises with relatively high polysulfone production capacity in my country.

Industry analysts said that polysulfone has excellent performance and is widely used in many fields. With the continuous release of market demand, the development trend of the industry Will keep getting better. Benefiting from national policy support and continuous technological innovation, the prosperity of my country’s polysulfone industry continues to increase. However, at present, my country’s local enterprises mainly produce mid-to-low-end polysulfone, and high-end products are highly dependent on imports. This is a major problem facing the development of the industry.
