Extrusion, Blow Molding, Injection Molding Grades PS is a subcategory of Polystyrene. It is specially formulated to extrusion, blow molding, injection molding grades. Its flexural modulus ranges from 220 to 341 MPa. Its tensile strength ranges from 4000 to 7500 MPa at break. Its flexural strength ranges from 6000 to 8000 MPa. Its Izod Impact strength ranges from 9 to 11 J/cm. Its elongation at break ranges from 25 to 40 %. Its hardness ranges from 85 to 90 Rockwell R. Its specific gravity ranges from 1.05 to 1.06. Its molding pressure ranges from 9 to 15 MPa.
Polystyrene, also known as PS, is a thermoplastic polymer. The most common trade name is Novacor 555. acrylonitrile / styrene / acrylic (ASA) 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.
Additional Information
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, 20% Glass Fiber Reinforced PS, Clear 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.
