GENERAL PROPERTIESUdel® Polysulfone is an amorphous high performance thermoplastic offering excellent mechanical, electrical, and improved chemical resistance relative to polycarbonate. Polysulfone's properties remain relatively consistent over a broad temperature range of -150°F (-100°C) to +300°F (+149°C).
Udel® offers hydrolysis resistance for continuous use in hot water and steam at temperatures up to 300°F (149°C). It offers high chemical resistance to acidic and salt solutions, and good resistance to detergents, hot water, and steam. In addition, polysulfone has excellent radiation stability and offers low ionic impurity levels.
Udel® is commonly used for analytical instrumentation, surgical and medical devices, and semiconductor process equipment components.
Food-grade Udel® polysulfone is FDA, NSF, 3A-Dairy and USP Class VI compliant. It may also be ordered in custom colors.
