Title (EN) MULTILAYER POLYMERIC STRUCTURES
(FR) STRUCTURES POLYMÈRES MULTICOUCHES
Abstract:
(EN) A multilayer composite structure is disclosed. The multilayer composite structure has at least one polymer-based cap layer containing, for example, an acrylic, styrenic or acrylonitrile polymer and at least one polyester-based inner or substrate layer. Also disclosed are methods of forming the multilayer composite structure to improve and control the level of adhesion between the layers. Optional tie layers can be used to improve and control the level of adhesion between the layers. An optional exterior layer over the cap layer can contain polyvinylidene fluoride (PVDF) polymers. The multilayer composite structure combines the attributes of both polymers - the high UV stability, scratch resistance, and excellent appearance of the polymer-based outer cap layer and the strength and impact resistance of the polyester-based interior layer.
(FR) L'invention concerne une structure composite multicouche. La structure composite multicouche comprend au moins une couche de recouvrement à base de polymère contenant, par exemple, un polymère acrylique, styrénique ou acrylonitrile et au moins une couche interne ou substrat à base de polyester. L'invention concerne également des procédés de formation de la structure composite multicouche en vue d'améliorer et de réguler le niveau d'adhérence entre les couches. Des couches de liaison facultatives peuvent être utilisées en vue d'améliorer et de réguler le niveau d'adhérence entre les couches. Une couche extérieure facultative sur la couche de recouvrement peut contenir des polymères de fluorure de polyvinylidène (PVDF). La structure composite multicouche combine les attributs des deux polymères : la stabilité aux UV élevée, la résistance aux rayures et un excellent aspect de la couche de recouvrement externe à base de polymère, et la force et la résistance aux chocs de la couche intérieure à base de polyester.
