Material Notes:
Polyphenylenesulfone is an amorphous material, with improved impact and hydrolysis resistance compared to PSU. The usual operating temperature is approximately 180°C. The extremely high notched impact strength remains also after a heat aging.Propertieshigh strength and rigidityvery high impact strengthvery good dimensional stabilityvery high chemical resistancehigh resistance to all kinds of radiationrepeated sterilizationlower chemical resistance than comparable semi-crystalline materialsApplications include parts for microwave ovens, blow dryers, parts for humidifiers, food industry, pump wheels, insulators, and medical industry.
