Olefin Rubber Modified PS is a subcategory of Polystyrene. The additative is added during the manufacturing process. Its flexural modulus ranges from 280 to 300 MPa. Its flexural strength ranges from 7700 to 8900 MPa. Its Izod Impact strength ranges from 13 to 15 J/cm. Its elongation at break ranges from 15 to 30 %. Its hardness ranges from 100 to 102 Rockwell R. Its melting temperature ranges from -55 to 110 °C. Its molding pressure ranges from 1 to 2 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, 20% Glass Fiber Reinforced 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.
