Germany, the United States, and China are the leading exporters of polysulfone (CAS 25135-51-7), collectively accounting for over 60% of global export value in 2023–2024; major importers include South Korea, Japan, and Mexico, reflecting strong demand from electronics, medical device, and automotive sectors. Export volumes from Germany and the U.S. remained stable year-on-year, while polysulfone prices edged upward modestly amid tightening supply of high-purity grades and sustained industrial demand.
Polysulfone (CAS 25135-51-7) is a high-performance, amorphous thermoplastic polymer appearing as a translucent to amber-colored solid in pellet or powder form; it exhibits high thermal stability (glass transition temperature ~185–190 °C), excellent mechanical strength, and inherent flame resistance. It is classified as an aromatic heterochain polymer, synthesized via step-growth condensation polymerization of bisphenol A and 4,4′-dichlorodiphenyl sulfone. Polysulfone is primarily used as an engineering thermoplastic—not as a chemical intermediate—but valued for its dimensional stability, hydrolytic resistance, and sterilizability. Its principal applications are in medical devices (e.g., dialysis membranes, surgical instrument handles), water filtration membranes, food processing equipment, and aerospace and automotive components requiring long-term performance under heat and stress.
