PPSU is an amorphous high performance thermoplastic that offers better impact resistance and chemical resistance than PSU and PEI. It offers superior hydrolysis resistance when compared to other amorphous thermoplastics. PPSU is an excellent choice for medical devices as steam autoclaves are widely used to sterilize medical devices. It also resists common acids and bases over a broad temperature range. PPSU is also suitable for use in electronic assembly equipment and devices that must withstand solder temperatures.
