Wilmington FibrePolysulfone
Polyarylsulfones (PSU) belong to the group of polysulfones and are thermoplastic, transparent plastics. Due to their amorphous molecular structure, polysulfones are translucent and have a light brown tint. Polysulfone (PSU) is a high temperature plastic with high mechanical strength and rigidity. Apart from the high continuous use temperature, the outstanding characteristics of the material include good creep strength that is remarkably high over a wide range of temperatures, excellent dimensional stability, very good resistance to hydrolysis and good chemical compatibility.
