PPSU is a type of high temperature aromatic sulfone polymer. For a long time, it has been considered as one of the most excellent composite polymers in plastic field. PPSU can be used under a high temperature of 180˚C, PPSU has an excellent hydrolysis resistance and able to resist common acid and bases over a broad temperature range.
PPSU also offers superior high heat deflection temperature, able to withstand repeated steam sterilization, good electrical properties, and resistance to environmental stress cracking.
Since PPSU has excellent resistance in heat and chemical, therefore which is suitable to demanding applications such as aerospace, automotive and chemical industries.
