20-30% Glass Fiber Reinforced PES is a subcategory of Polyethersulfone. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 1150 to 1550 MPa. Its flexural modulus ranges from 980 to 1300 MPa. Its tensile strength ranges from 20000 to 22000 MPa at break. Its flexural strength ranges from 26500 to 28500 MPa. Its Izod Impact strength ranges from 1.4 to 1.7 J/cm. Its elongation at break ranges from 2.1 to 2.8 %. Its hardness ranges from 96 to 97 Rockwell M. Its specific gravity ranges from 1.53 to 1.6. Its coefficient of thermal expansion ranges from 12 to 14 x 10-6/°C.
Polyethersulfone, also known as PES, is a thermoplastic polycondensate. It is rigid with high strength, transparent, and it retains its properties between 100°C and 150 °C. It has very high dimensional stability with reproducible properties and controllable size of pores. PES is commonly used as membrane filters in applications such as hemodialysis, waste water recovery, food and beverage processing, and gas separation. Polysulfone has the highest service temperature of all melt-processable thermoplastics.
Additional Information
Other common Polyethersulfone (PES) include 10% Glass Fiber Reinforced PES, 20% Mineral Filled PES, 30% Carbon Filled PES, and Reinforced PES.
