20% Glass Fiber Reinforced PSU is a subcategory of Polysulfone. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 825 to 1130 MPa. Its flexural modulus ranges from 750 to 980 MPa. Its tensile strength ranges from 15200 to 20000 MPa at break. Its flexural strength ranges from 23500 to 27600 MPa. Its compressive strength ranges from 19500 to 24000 MPa. Its Izod Impact strength ranges from 1.1 to 1.7 J/cm. Its elongation at break ranges from 2 to 3.5 %. Its hardness ranges from 96 to 99 Rockwell M. Its specific gravity ranges from 1.51 to 1.53. Its coefficient of thermal expansion ranges from 23 to 32 x 10^-6/°C. Its melting temperature ranges from 220 to 225 °C. Its molding pressure ranges from 6 to 100 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.
