PSU (Polysulfone) is a non-crystalline thermoplastic super engineering plastic, with excellent transparency, heat resistance, steam disinfection resistance, outstanding creep resistance and high physical and mechanical properties, excellent chemical corrosion resistance.
Polysulfone is an ideal material for making water film and hemodialysis film. It has excellent biocompatibility, good thermal stability, resistance to steam disinfection, and is easy to process and soluble.
The film can be widely used in food, pharmaceutical, biological, chemical, environmental protection, medical and other industries.
Main features:
Polysulfone is widely used in the electronics industry, mainly for the manufacture of electronic equipment enclosures, sockets, cables and batteries. Polysulfone has good insulation properties, mechanical properties, high temperature resistance and flame retardant properties, which can effectively protect electronic equipment and improve the safety and reliability of electronic equipment. In addition, Polysulfone can also be manufactured circuit boards, electrical appliances and optical devices.
The application of Polysulfone in the automotive industry is mainly reflected in the manufacturing of automotive parts,such as brake systems, water tanks and air conditioning systems.
Polysulfone has excellent high temperature stability and chemical stability, making auto parts more durable.
In addition, Polysulfone can also be used to manufacture automotive lightweight materials, which can greatly reduce the weight of the vehicle and improve the fuel economy and environmental performance of the vehicle.
