Its Izod Impact strength ranges from 0.65 to 1 J/cm. Its elongation at break ranges from 2 to 5 %. Its hardness ranges from 70 to 74 Rockwell M. Its specific gravity ranges from 1.48 to 1.61. Its coefficient of thermal expansion ranges from 34 to 39 x 10^-6/°C. Its molding pressure ranges from 10 to 20 MPa.

Polysulfone, also known as PSU, is a thermoplastic polycondensate. The most common trade name is Ultrason. polysulfone It is an expensive material. It is electroplatable and has high strength, good toughness, good dielectric strength, and dimensional stability. It is commonly used in electric connectors.
