Among those that are commercially Thus, it is classified as a hydrocarbon. PS is made by the polymerization of styrene which is a kind of building block material used to produce a variety of plastic products. disposable consumer plastic goods as well as parts for optical, electronic/electrical, However, HIPS has gloss, which is measured by the percentage of light reflected by the surface of the polymer. The higher density makes XPS more rigid and strong. Despite all these weaknesses, styrene polymers are very attractive large-volume commodity plastics. One of the major uses of polystyrene is in the manufacture of polystyrene foam for packing objects for shipment. The copolymer poly(styrene-co-maleic anhydride) (PSMA) The expanded or foamed polystyrene is thermally insulating, has high impact resistance and good processability. Polystyrene is a versatile thermoplastic that is available in a wide range of formulations. To increase the heat resistance, styrene is sometimes copolymerized with small amounts of maleic anhydride or it is copolymerized tensile strength (35 - 55 MPa) but low impact strength (15 - 20 J/m). The advantage of thermoplastics is that they can be molded into a host of useful products. Polystyrene is one of the most important commodity plastics. lower-cost and lower-density resins to gain market share in Polystyrene polymers get degraded on exposure to sunlight, due to photo oxidation, which affects its mechanical properties.
