PPSU is an amorphous high performance thermoplastic offering better impact resistance and chemical resistance than polysulfone and polyetherimide. PPSU 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. 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.
