Details: Sultron® Polysulfone (PSU) 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).; Sultron® PSU 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).; Sultron® PSU 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. Sultron® PSU 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.
