Polystyrene (PS) , is a synthetic resin made by homopolymerization of styrene monomers or with other comonomers. In the molecular structure of homopolymer, the main chain is a saturated carbon chain   with   benzene   rings   as   the   lateral   group. The   resin   is   a non-crystalline linear polymer, which is colorless, transparent, hard, easy to be dyed and resistant to chemical solutions. It has excellent electrical insulation property and low hygroscopicity. It is easy to mold and has good fluidity. It can be made into a variety of products through injection molding, extrusion, compression molding, vacuum molding and foaming. The products have stable dimensions and low shrinkage   during molding and the molding term is short.

PS can be mainly classified into general-purpose PS (GPPS) and high-impact PS (HIPS). These resins are widely used in automobiles, electronic and electrical appliances, apparatus parts, buildings, medical care, etc. GPPS can be used to make daily necessities, electrical instrument shells, toys, lamps, cosmetic containers,   decorations, optical parts (such as triangular prisms and lens), auto   headlights,   telecom   accessories,   capacitor   films,   high-frequency insulating materials, waveguide tubes, chemical vessels, structural foam products, etc. HIPS can be used to make shells of electrical household appliances,   refrigerator lining, plates, TV sets, recorders, telephone body cases, stationary, toys, packaging vessels, daily necessities, dishware, etc.
