Polysulfone – PSU

PSU 1000 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 to 300°F (-100°C to 100°C). PSU 1000 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 1000 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.

Available in sheet and rod form.
