Radel® / PPSU (Polyphenylsufone)

Radel® is a high-performance thermoplastic offering better impact and chemical resistance than polysulfone or polyetherimide (Ultem®). Radel® has exceptional toughness and outstanding hydrolysis resistance when compared to other thermoplastics as measured by steam autoclaving cycles to failure. Because Radel® has the ability to withstand a virtually unlimited number of steam sterilizations; it typically is used for medical devices without loss of dimensional stability or physical properties. Radel® also resists common acids and bases—including commercial washing solutions—over a broad temperature range. Typical applications include sterilization trays, dental and surgical instrument handles and food service trays. It is also suitable for use in electronic assembly equipment and devices that must withstand solder temperatures. Its heat deflection temperature is 405° F. Radel® is FDA, USDA and USP Class VI compliant.
