PESU (Polyether sulfone) is a kind of amorphous thermoplastic super engineering plastic. It has excellent heat resistance, high mechanical strength, food contact, etc., especially with the advantages of continuous use at high temperatures and good dimensional stability in the environment of rapid temperature changes.
Polyether sulfone 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.
