Unfilled PSU is a subcategory of Polysulfone. The additative is added during the manufacturing process. Its elastic modulus ranges from 350 to 410 MPa. Its flexural modulus ranges from 348 to 380 MPa. Its tensile strength ranges from 9800 to 13800 MPa at break. Its flexural strength ranges from 17000 to 18700 MPa. Its compressive strength ranges from 11800 to 15600 MPa. Its elongation at break ranges from 6 to 80 %. Its hardness ranges from 85 to 88 Rockwell M. Its specific gravity ranges from 1.37 to 1.46. Its melting temperature ranges from 220 to 230 °C. Its molding pressure ranges from 6 to 20 MPa.

Polysulfone, also known as PSU, is a thermoplastic polycondensate. The most common trade name is Ultrason. poly(ethersulfone) 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.
