Polystyrene (PS) is a synthetic polymer derived from the monomer styrene. This comparatively inexpensive plastic resin can be found in solid or foam form, and it is one of the most widely used plastics in the world with production being in the billions of kilograms annually. This material is most commonly extruded, vacuum formed or injection molded when being manufactured into products for the end market. As with most plastics, PS is a versatile material and is used for a wide range of applications. Perhaps the most famous brand and type of PS is Styrofoam, which was developed by Dow Chemical in 1941.

Polystyrene is used in the production of many types of clamshell packaging, CD cases, disposable cutlery and dinnerware, frames, test tubes, Petri dishes, and many other such applications where a strong, low-cost plastic is required. The most common manufacturing methods used in the production of such PS products are injection molding and vacuum forming. In addition to the uses stated above, Polystyrene is probably best known to the public as a form of protective packaging when shipping items.

Some other applications of PS are in expanded foam form and, as PS is a good thermal insulator, such foams are often used in the production of building insulation materials.
