Sultron™ PPSU polyphenylsulfone (PPSU) is an amorphous high performance thermoplastic offering better impact resistance and chemical resistance than polysulfone and polyetherimide (Duratron® PEI).
Sultron™ PPSU offers superior hydrolysis resistance when compared to other amorphous thermoplastics as measured by steam autoclaving cycles to failure. In fact, Sultron™ PPSU has virtually unlimited steam sterilizability. 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.
Sultron™ PPSU is stocked in natural (bone white) and available in custom colors. It is commonly used in sterilization trays, dental and surgical instrument handles, and in fluid handling coupling and fitting applications. Sultron™ PPSU is USP Class VI compliant. It is suitable for use in electronic assembly equipment and devices that must withstand solder temperatures. PPSU has a heat deflection temperature of 207 °C (405 °F).
