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 (See Figure 14). It is commonly used for analytical instrumentation, medical devices and semiconductor process equipment components.
Food-grade Sultron® PSU Polysulfone and custom colors can be special ordered. Only food-grade PSU is FDA, NSF, 3A-Dairy, USP Class VI compliant and meets the compliance to requirements of NSF/ANSI standard 61.
