Polysulfone (PSU)

1. Electrical appliances, electronics

Taking advantage of PSU's solder resistance, good dimensional stability, resistance to various cleaning agents, inlay metal parts, and good adhesion with epoxy resin, it is used as a Class H insulating material in the electronics and electrical fields.

2. Medical appliances, food processing machinery

It can be sterilized by steam sterilization, dry steam (180) sterilization, V-ray sterilization and other sterilization methods, and can be resistant to repeated sterilization. The main products developed include contact lens sterilizers, dental drill handles, etc., valves for the food industry, etc.

3. Hot water field

It is mainly used to maintain excellent creep resistance, rigidity and dimensional stability in 160 hot water or steam. The main products developed include valves for hot water and steam, insulators for anti-corrosion electrodes, components for temperature sensors, pump bodies and impellers for various liquid and powder pumps, radiator valves, parts for ultrafiltration devices, etc.
