Udel® P-1700 polysulfone (PSU) is a tough, rigid, high-strength thermoplastic suitable for continuous use up to 300 °F (149 °C). It is resistant to oxidation and hydrolysis and withstands prolonged exposure to high temperatures and repeated sterilization. Udel® P-1700 polysulfone is highly resistant to mineral acids, alkali and salt solutions. This resin is also highly resistant to degradation by gamma or electron beam radiation. Electrical properties of Udel® P-1700 polysulfone are stable over a wide temperature range and after immersion in water or exposure to high humidity.
Udel P-1700 complies with FDA 21 CFR 177.1655 and may be used in articles intended for repeated use in contact with foods. Additionally, this material is approved by the NSF, by the Department of Agriculture for contact with meat and poultry and by the 3-A Sanitary Standards of the Dairy Association.
This material is available in pellet form that can be used with standard plastic processing equipment. The material pellets are transparent and have a slight blue tint appearance.
