PSU 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).

PRODUCT OVERVIEW.

• High maximum allowable service temperature in air (150°C continuously) 
• Good hydrolysis resistance (suitable for repeated steam sterilization)
• High strength and stiffness over a wide temperature range 
• Good dimensional stability
• Physiologically inert (suitable for food contact)
• Very good resistance against high energy radiation (gamma- and X-rays)
• Good electrical insulating and dielectric properties

PSU 1000 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).

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. 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 PSU Polysulfone and custom colors can be special ordered. Only food-grade PSU is FDA, NSF, 3A-Dairy and USP Class VI compliant.
