Radel® R polyphenylsulfone (PPSU) is an amorphous high performance thermoplastic offering better impact resistance and chemical resistance than polysulfone and polyetherimide (Ultem® PEI) as with Figures 15 and 16.
Radel 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 (See Table 3). This factor makes it an excellent choice for medical devices as steam autoclaves are widely used to sterilize medical devices. It also resists common acids and bases — including commercial washing solutions — over a broad temperature range.
Radel R is stocked in natural (bone white) and available in transparent and custom colors. It is commonly used in sterilization trays, dental and surgical instrument handles, and in fluid handling coupling and fitting applications. Radel R is USP Class VI compliant. It is suitable for use in electronic assembly equipment and devices that must withstand solder temperatures. Radel has a heat deflection temperature of 405®F (207®C).
Medical Wands Radel rod is intricately machined into smooth, comfortable handles used as structural components in medical applications. These handles offer superior impact resistance and autoclavability. (Prior material: Stainless Steel)
Endoscopic Probe Positioning Ferrule For endoscopic surgical devices, a positioning ferrule on the instrument handle is intricately machined from Radel R rod. (Prior material: Stainless Steel)
Engineering Notes Radel is not a wear material, and its properties degrade when exposed to sunlight.
