Impact Modified High Heat Resistant PS is a subcategory of Polystyrene. The additative is added during the manufacturing process. Its elastic modulus ranges from 280 to 330 MPa. Its flexural modulus ranges from 320 to 370 MPa. Its tensile strength ranges from 4600 to 5800 MPa at break. Its flexural strength ranges from 8500 to 10500 MPa. Its Izod Impact strength ranges from 1.5 to 4 J/cm. Its elongation at break ranges from 10 to 20 %. Its hardness ranges from 75 to 95 Rockwell R. Its specific gravity ranges from 1.05 to 1.08. Its coefficient of thermal expansion ranges from 67 to 79 x 10-6/°C.
Polystyrene, also known as PS, is a thermoplastic polymer. The most common trade name is Novacor 555. 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.
