UDEL® P-1700 Natural Polysulfone (PSU) is a semi-transparent (Amber color), 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 UL94 V0 at .177” thickness (4.5mm).  UDEL®  Polysulfone offers high chemical resistance to acidic and salt solutions, and good resistance to detergents, hot water and steam.  In addition, polysulfone is highly resistant to degradation by gamma or electron beam radiation, and offers low ionic impurity levels.  Electrical properties of UDEL Polysulfones are stable over a wide temperature range and after immersion in water or exposure to high humidity.  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.  Contact customer service for a complete list of physical, mechanical, thermal and electrical properties.

Radel®R is a Polyphenylsulfone (PPSU) suited primarily to applications in the medical industry.  Radel®R is similar to Polysulfone (PSU) but has improved performance in terms of temperature, impact strength and chemical resistance.  Radel®R  also has exceptional resistance to repeated steam autoclaving without loss of dimensional stability or physical properties.
