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 ...
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]
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.
Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2.Its structure consists of a vinyl group as substituent on benzene.Styrene is a colorless, oily liquid, although aged samples can appear yellowish.
The solubility of SMA in alkaline solutions makes it suitable for various applications in the field of sizings (paper), binders, dispersants and coatings. The specific reactivity of SMA makes it a suitable agent for compatibilizing normally incompatible polymers (e.g. ABS/PA blends) or cross-linking.
Polystyrene is manufactured in various forms that have different applications and can have medium to very low density. Extruded polystyrene (PS or xPS, sometimes colored pink/blue) is used in the manufacture of disposable cutlery, rigid ground contact rated insulating foam board, CD and DVD cases, plastic models of cars and boats, and smoke ...
Kraton polymers are styrenic block copolymer (SBC) consisting of polystyrene blocks and rubber blocks. The rubber blocks consist of polybutadiene, polyisoprene, or their hydrogenated equivalents. The tri-block with polystyrene blocks at both extremities linked together by a rubber block is the most important polymer structure observed in SBC.
Free radical polymerization has found applications including the manufacture of polystyrene, thermoplastic block copolymer elastomers, [29] cardiovascular stents, [30] chemical surfactants [31] and lubricants. Block copolymers are used for a wide variety of applications including adhesives, footwear and toys.
