Rubber-Modified High Impact PS is a subcategory of Polystyrene. The additative is added during the manufacturing process. Its elastic modulus ranges from 160 to 370 MPa. Its flexural modulus ranges from 160 to 390 MPa. Its tensile strength ranges from 1900 to 6200 MPa at break. Its flexural strength ranges from 3300 to 10000 MPa. Its Izod Impact strength ranges from 0.95 to 7 J/cm. Its elongation at break ranges from 20 to 65 %. Its hardness ranges from 50 to 82 Rockwell R. Its specific gravity ranges from 1.03 to 1.06. Its melting temperature ranges from 9.3 to 105 °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. 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.
