Il est commercialisé sous plusieurs noms : Makrolon de Covestro, Lexan de Sabic, Hammerglass, Xantar de . Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worke molde and thermoformed. Because of these properties, polycarbonates . Polycarbonate ( PC ) plastic is used for many applications requiring high impact resistance and transparency.
Découvrez toutes les caractéristiques du polycarbonate.
Compact discs, riot shields, vandal proof glazing, baby feeding bottles, electrical components, safety helmets and headlamp lenses are all typical . If you continue without changing these settings, you consent to this – but if you want, you can change your settings at any time at the bottom of this page. A polycarbonate molecule is composed by a Bisphenol A part and a carbonate group. This amorphous structure gives the polymer its particular transparency. Polycarbonate possesses excellent impact strength, high heat resistance and good dimensional stability.
It was one of the first thermoplastics to offer these properties. Although it is stable to water, mineral and organic acids, it is partially soluble in aromatic hydrocarbons, soluble in the chlorinated ones, and decomposes in . The most common system for this polymerization is formed by a reaction of bisphenol A and phosgene.
Applications of polycarbonate are almost always those which take advantage of its . It is extremely robust, lightweight with glass-like transparency . It is autoclavable, non-toxic, and the toughest of all thermoplastics. PC is a special type of polyester in which dihydric phenols are joined through carbonate linkages. These linkages are subject to chemical reaction with bases and concentrated acids, . Présentation du polymère. Propriétés physico-chimiques. Références bibliographiques : 1-3.
Les meilleurs solvants du polycarbonate pour les opérations de nettoyage (par exemple) sont. This resin type is versatile and easily worked and molded. Le polycarbonate est un polymère thermoplastique amorphe.
Parmi les matières plastiques transparentes, il est celui qui présente les meilleures performances mécaniques. POLYCARBONATE ( PC ) naturel (incolore, translucide). Caractéristiques principales: haute résistance mécanique, bonne résistance au fluage, très haute résistance aux chocs, même à basse .
