Hot Water & Steam Performance to 300 degrees Fahrenheit Characteristics: - Hydrolysis resistant - Radiation stability - Broad temperature range capability - Low ionic impurity - Good thermal and electrical insulation characteristics Udel® polysulfone is an amber semi-transparent, heat-resistant, high performance engineering thermoplastic. It offers excellent mechanical, electrical and improved chemical resistance properties relative to polycarbonate. Polysulfone's properties remain relatively consistent over a broad temperature range from -150°F (-100°C) to 300°F (100°C). Udel® polysulfone is hydrolysis resistant for continuous use in hot water and steam at temperatures up to 300°F. Its flame resistance is UL 94-V-0 at 1/4" thickness (6.35mm) and UL 94-V-2 at 1/8" thickness (3.175mm). Udel® polysulfone 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® polysulfone often replaces polycarbonate when higher temperatures, improved chemical resistance or autoclavability is required. It is commonly used for analytical instrumentation, medical devices and semiconductor process equipment components. Food-grade Udel® polysulfone and custom colors can be special ordered. Only food-grade is FDA, NSF, 3A-Dairy and USP Class VI compliant.
