General Description: Polyphenylsulfone (PPSu) is an amorphous high performance thermoplastic, offering better impact resistance and chemical resistance than polysulfone and polyetherimide. It offers superior hydrolysis resistance when compared to other amorphous thermoplastics, as measured by steam autoclaving cycles to failure. In fact PPSu has virtually unlimited steam sterilizability, outlasting other materials by a factor of 40:1. 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.

Industrial applications include sterilization trays, dental and surgical instrument handles, hot water fittings & aircraft cabin interior components.
