Aramid sulfone fiber (PSA) has broad application prospects and the domestic market supply capacity is gradually improving


Aramid sulfone fiber, the full name of polyphenylsulfone terephthalamide fiber, referred to as PSA, refers to a high-temperature resistant and flame-retardant aromatic synthetic fiber with a special molecular structure, consisting of 25% meta structure and 75% para structure. composition. Aramid fiber has excellent mechanical properties, temperature resistance, flame retardancy, thermal stability, electrical insulation properties, corrosion resistance, radiation resistance, etc., and has been used in metallurgy, fire protection, environmental protection, industrial protection, aerospace, national defense, etc. Widely used in military industry and other fields.
Specifically, in the field of industrial protection, arylsulfone fiber is a key material for making protective clothing such as fire-fighting suits and special work clothes; in the aerospace field, arylsulfone fiber has been used to make seat covers and door curtains in the domestic large aircraft C919. The raw material is one of the key materials for lightweighting aircraft; in the field of environmental protection, arylsulfone fiber can be used in the manufacturing of filtration products such as flue gas dust filter bags and hot gas filter hoses. With the rapid development of downstream application fields, the market demand for arylsulfone fiber in my country continues to increase, and the industry shows good development prospects.
According to the“2023-2028 Arylsulfone Fiber (PSA) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center shows that arylsulfone fiber is one of the aromatic high-temperature resistant synthetic fibers. It is a basic raw material for advanced protective materials and structural materials, and the manufacturing process is extremely complex. Only a few companies in developed countries have mass production capabilities for similar fibers, such as DuPont’s Nomex fiber (aramid 1313 fiber) in the United States, and the process technology is strictly confidential. Against this background, in order to meet market demand, my country has increased its research and development efforts and successfully developed aramid fiber, which can successfully replace imported aramid fiber.
Aramid sulfone fiber is a high-tech fiber product successfully developed by my country and has independent intellectual property rights. Aramid sulfone fiber was first jointly developed by the Shanghai Institute of Textile Science, Shanghai No. 8 Chemical Fiber Factory and other institutions. After recent years of development, my country has already had companies such as Shanghai Te’anlun Fiber and Zhongfang New Materials with large-scale production of this product. Mass production capability.
Among them, Zhongfang New Materials is a leading enterprise in the domestic aramid sulfon fiber industry. Up to now, the company’s aramid sulfon fiber batch production line has been fully put into operation, and can achieve an annual production capacity of 1,000 tons of aramid sulfon fiber. With the gradual release of production capacity of local enterprises, the pace of domestic substitution in the domestic aramid fiber market is continuing to accelerate, and the development trend of the industry is improving.
Industry AnalysisPersonnel said thatarylsulfone fiber is an aromatic synthetic fiber independently developed in my country. It is a key raw material for protective materials and structural materials. It has been implemented in metallurgy, industrial protection, aerospace and other fields. widely used. Aramid sulfone fiber can replace imported aramid fiber and break the technical monopoly of foreign aromatic high-temperature resistant synthetic fibers. At present, the aramid sulfone fiber batch production line of Zhongfang New Materials, a leading domestic enterprise, has been put into operation. In the future, the supply capacity of the domestic market will be greatly improved. Improvement, the overall development trend of the industry is improving.
