Overview :

PSU (polysulfone) is an amber transparent material with good stiffness and strength, semi-toughness. Its transparency is better than PPSU (polyphenylene sulfone) and PES (polyethersulfone). Compared with PC (polycarbonate), PSU can offer higher heat resistance and better hydrolytic stability. The material PSU has passed FDA, EU10/2011, NSF14/61, ACS, WRAS, W270, UL94, REACH, ROHS and other certifications. As a polysulfone material with excellent comprehensive properties, PSU can be used in water filtration membranes, water pipe joints, water dispenser parts, hemodialysis membranes, SF products and so on.
