Introduction of PS
General-purpose polystyrenre, a.k.a. hard rubber, is produced by heating and polymerizing phenylethane monomers. The general-purpose polystyrenre is shiny, light and cheap. Its properties can be modified by adding rubber into the production process, in which the high-impact non-transparent PS (High Impact Polystyrene, HIPS) is formed. This product is commonly used in trays and spacers for electronic products.
