20% Glass Fiber Reinforced PS is a subcategory of Polystyrene. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 1200 to 1710 MPa. Its flexural modulus ranges from 1000 to 1280 MPa. Its tensile strength ranges from 15500 to 18000 MPa at break. Its flexural strength ranges from 20000 to 22700 MPa. Its compressive strength ranges from 17000 to 21000 MPa. Its Izod Impact strength ranges from 1 to 3 J/cm. Its elongation at break ranges from 1.2 to 1.8 %. Its hardness ranges from 89 to 100 Rockwell M. Its specific gravity ranges from 1.22 to 1.4. Its coefficient of thermal expansion ranges from 23.4 to 41.4 x 10-6/°C. Its molding pressure ranges from 10 to 20 MPa.
Polystyrene, also known as PS, is a thermoplastic polymer. The most common trade name is Novacor 555. styrene / acrylonitrile, copolymer It is an inexpensive material that is not structurally strong but easy to mold. It machines well, and is highly transparent. PS is commonly used for inexpensive packaging materials, pens, safety razors, flatware, and CD jewel boxes. In Styrofoam forms, PS is used to make high-throughput, thin-walled, easy-to-mold parts where structure is not paramount.
Other common Polystyrene (PS) include High and Medium Flow PS, Heat Resistant PS, 20% Long and Short Glass Fiber Reinforced PS, Rubber-Modified Flame-Retardant, UL-V0 PS, Rubber-Modified High Impact PS, Molding and Extrusion PS, Olefin Rubber Modified PS, Clear PS, Extrusion, Blow Molding, Injection Molding Grades PS, Clear Styrene Butadiene Copolymers PS, Molding and Extrusion PS, Impact Modified PS, 20% Glass Fiber Reinforced PS, High Heat Resistant, Injection Molding PS, Impact Modified High Heat Resistant PS, 20% Glass Fiber Reinforced High Heat Resistant PS, PS, and 20% PAN Carbon Fiber EMI Shielding (conductive) PS.
