Expanded polystyrene packaging A polystyrene yogurt container Bottom of a vacuum-formed cup; fine details such as the glass and fork food contact materials symbol and the resin identification code symbol are easily molded. Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic polymer made from monomers of the aromatic hydrocarbon ...
Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.
Polystyrene (thermocole) PS: Thermal insulator. Properties depends on the form, expanded form is tough and rigid: Petri dishes, CD case, plastic cutlery: Polytetrafluoroethylene: PTFE: Very low coefficient of friction, excellent dielectric properties, chemically inert
Among the earliest examples in the wave of new polymers were polystyrene (first produced by BASF in the 1930s) [4] and polyvinyl chloride (first created in 1872 but commercially produced in the late 1920s). [4] In 1923, Durite Plastics, Inc., was the first manufacturer of phenol-furfural resins. [130]
One of the better-known examples of a graft polymer is a component used in high impact polystyrene, consisting of a polystyrene backbone with polybutadiene grafted chains. The graft copolymer consists of a main polymer chain or backbone (A) covalently bonded to one or more side chains (B)
styrene can break off from polystyrene and styrene is a very potent carcinogen,” he said. ... For example, sometimes he forgets his stainless steel mug and is “desperate for (his) caffeine hit ...
Polystyrene integrated solid foams are not commonly used in biomedical applications but have shown promise as a new drug delivery vehicle. The manipulation of the porous foam networks is a fundamental component in solid foam dosing – affecting variables such as dissolution, adsorption, and drug diffusion. [4]
