Some people buy and use them for disposable products. Styrofoam is also known as Plastic #6 and Expanded Polystyrene Foam. It is made from styrene monomer. The fractions are then mixed with chemical compounds consisting of carbon and hydrogen which are called hydrocarbon chains. A popular brand of polystyrene is called Styrofoam. Despite its advantageous properties, polystyrene is brittle and flammable; it also softens in boiling water and, without the addition of chemical stabilizers, yellows upon prolonged exposure to sunlight. The strength of EPS foam along with its shock absorbing properties makes it effective for use in children’s seats and cycling helmets. Polystyrene is produced by heating styrene monomer, generating a reaction that causes the styrene units to attach to each other and form the long chain polymer known as polystyrene. The polymerization of styrene has been known since 1839, when German pharmacist Eduard Simon reported its conversion into a solid later named metastyrol. Now foamed by pentane or carbon dioxide gas, polystyrene is made into insulation and packaging materials as well as food containers such as beverage cups, egg cartons, and disposable plates and trays. Both these materials are thermoplastic and rigid. Polystyrene is made from the monomer styrene which is a liquid petrochemical. Polystyrene is also copolymerized, or blended with other polymers, lending hardness and rigidity to a number of important plastic and rubber products. Styrene is produced from ethylene and benzene. How Is Polystyrene Made. Most plastics are made from oil, where heavy crude oil is separated into fractions. It is made up from closed-cell tough foam constituted from polystyrene beads and it provides superb insulation. Through polymerization, styrene is refined into polystyrene and then a hydrofluorocarbon agent is added. Polystyrene is formed from the polymerisation of the vinyl monomer, styrene. Styrene also occurs naturally in foods such as strawberries, cinnamon, coffee and beef. Styrene is produced from benzene and ethylene, and is polymerised in the presence of catalysts, usually organic peroxides. Extruded polystyrene is another form of foam made from polystyrene. Polystyrene has an exceptionally long history, being discovered in 1839 by an apothecary named Eduard Simon. This article was most recently revised and updated by, https://www.britannica.com/science/polystyrene, United States Environment Protection Agency - Polystyrene. Polystyrene is produced from the crude oil refinery product styrene. Read More on This Topic major industrial polymers: Styrene-maleic anhydride copolymer Polystyrene is a thermoplastic substance that normally exists in solid state at room temperature, but melts if heated (for molding or extrusion), and becomes solid again when cooled. All of these insulation products have their good points as well as their bad. This rigid, relatively brittle thermoplastic resin is polymerized from styrene (CH. For manufacturing expanded polystyrene, the polystyrene beads are impregnated with the foaming agent pentane. Solid polystyrene is transparent, owing to these large, ring-shaped molecular groups, which prevent the polymer chains from packing into close, crystalline arrangements.
