GENERAL PROPERTIES Radel® R PAES (Polyarylethersulfone) is an amorphous high performance thermoplastic offering better impact and chemical resistance than polysulfone (Udel®) or polyetherimide (Ultem®). Polyarylethersulfone is also commonly referred to as Polyphenylsulfone (PPSU).
Radel® R offers superior hydrolysis resistance when compared to other amorphous thermoplastics as measured by steam autoclaving cycles to failure. In fact, Radel® R has virtually unlimited steam sterilizability. This makes it an excellent choice for medical devices. It also resists common acids and bases -- including commercial washing solutions -- over a broad temperature range.
Radel® R is available in amber (translucent), natural (bone white), and custom colors. It is commonly used in sterilization trays, dental and surgical instrument handles, orthopedic implant trials and in fluid handling coupling and fitting applications. Radel® R is FDA, USDA, and USP Class VI compliant.
