Overview :

PSU (polysulfone) is an amber transparent plastic material with good mechanical properties such as good stiffness and strength, semi-toughness and high temperature. 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. Tuntun Plastic is a professional polysulfone manufacturer providing high quality psu material and psu rods at wholesale prices. Shop for PSU Rods & Sheets >>

Polysulfone is an amorphous high performance thermoplastic that offers excellent mechanical and electrical properties, as well as chemical resistance to acidic and salt solutions. These properties remain constant over a relatively broad temperature range (-150º F to 300º F). The melting point of Polysulfone (PSU) is approximately 232°C (450°F).

Polysulfone Applications

Polysulfone is used in several applications including:

  • Medical devices: Polysulfone is used to manufacture dialysis membranes, fluid management devices, and other medical equipment.
  • Aerospace: Polysulfone is used in fuel cells, air management systems, and other aerospace applications due to its high heat resistance and dimensional stability.
  • Electronics: Polysulfone is used as an insulator in electronic devices due to its high electrical resistance and dimensional stability.
  • Automotive: Polysulfone is used in automotive applications, such as fuel and brake lines, due to its high heat resistance and dimensional stability.
