Polysulfone (PSU) Global Market Insights 2025, Analysis and Forecast to 2030, by Manufacturers, Regions, Technology, Application

Polysulfone (PSU) Market Summary

The Polysulfone (PSU) market represents a specialized segment within the high-performance polymer industry, characterized by its superior thermal stability, mechanical strength, and chemical resistance. Polysulfone, typically produced via the polycondensation of bisphenol A sodium (or potassium) salt with 4,4'-dichlorodiphenyl sulfone, is an amorphous polymer exhibiting a slight amber hue and transparent or semi-transparent appearance. PSU demonstrates tensile and flexural strengths higher than standard engineering plastics, with a melting temperature range of 340℃–390℃ and a long-term service temperature between -100℃ and 150℃. Its excellent electrical insulation properties are maintained even under high-temperature and high-humidity conditions, making it a reliable material in demanding applications. PSU is stable against common inorganic acids, bases, salts, and various hydrocarbons, alcohols, and oils, though it may be affected by strong solvents such as concentrated sulfuric acid, nitric acid, or certain polar solvents including ketones, halogenated hydrocarbons, aromatics, and formamide. Its radiation resistance further enhances its utility in specialized engineering applications. The global PSU market is estimated to reach 350–700 million USD by 2025, with an anticipated compound annual growth rate (CAGR) of 7.6%–12.6% through 2030.
