Description

Poly(styrene) is white powder or beads, or clear solid.Polystyrene is rigid with excellent dimensional stability, has good chemical resistance to aqueous solutions, and is an extremely clear material.
Impact polystyrene contains polybutadiene added to reduce brittleness. The polybutadiene is usually dispersed as a discrete phase in a continuous polystyrene matrix. Polystyrene can be grafted onto rubber particles, which assures good adhesion between the phases. The specific gravity of ge

Polystyrene Use and Manufacturing

Polystyrene is used to produce disposable plastic cutlery, CD cases, smoke detector housings, license plate frames, plastic model assembly kits, and many other items that require a rigid, economical plastic. Production methods include thermoforming and injection molding. Polystyrene petri dishes and other laboratory containers play an important role in biomedical research and science. For these uses, the items are almost always made by injection molding and are usually sterilized after molding by irradiation or treatment with ethylene oxide. Post-molding surface modification usually uses an oxygen-rich plasma, often to introduce polar groups. Much modern biomedical research relies on the use of such products. Polystyrene foam contains 95–98% air and has good thermal insulation properties, so it is often used as a building insulation material, for example in insulated concrete forms and structural insulated board building systems. Gray polystyrene foam containing graphite has excellent thermal insulation properties. Expanded polystyrene is used to make food containers, building insulation moldings, and packaging materials, both as solid blocks to hold protected items and as loosely filled ""peanuts"" to cushion fragile items within a box. It is also widely used in automotive and road safety applications, such as motorcycle helmets and roadblocks on racing tracks. The vast majority of expanded polystyrene products are manufactured by injection molding. The mold tools are often made of steel (which can be hardened and plated) and aluminum alloys. The mold is controlled by a channel system consisting of gates and runners.
