Udel P-1700 polysulfone (PSU) is a tough, rigid, high-strength thermoplastics suitable for continuous use up to 300°F (149°C). It is resistant to oxidation and hydrolysis and withstand prolonged exposure to high temperatures and repeated sterilization. Udel P-1700 polysulfone is highly resistant to mineral acids, alkali and salt solutions. Resistance to ergents and hydrocarbon oils is good, but the resin may be attacked by polar solvents such as ketones, chlorinated hydrocarbons and aromatic hydrocarbons.
These resins are also highly resistant to degradation by gamma or electron beam radiation. Electrical properties of Udel P-1700 polysulfones are stable over a wide temperature range and after immersion in water or exposure to high humidity.
The resins comply with FDA 21 CFR 177.1655 and may be used in articles intended for repeated use in contact with foods. Additionally, they are 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.
