Abstract
(EN)
In one embodiment, a multilayer article comprises: a core layer comprising a core layer polycarbonate resin, a core flame retardant additive, and an opacity additive, and a cap layer comprising a cap layer polycarbonate resin and a cap flame retardant additive. The core layer comprises a sufficient amount of core flame retardant additive and the cap layer comprises a sufficient amount of cap flame retardant additive such that the multilayer article can pass a smoke density test as set forth in FAR 25.5, Appendix F, Part V. In one embodiment, a method of making a multilayer article comprises: forming a core layer comprising a core layer thermoplastic resin, and a core non-brominated flame retardant additive, and forming a cap layer comprising a cap layer thermoplastic resin, a cap non-brominated flame retardant additive, and thermoforming the multi-layer film.

L'invention concerne, dans un mode de réalisation, un article multicouche comprenant : une couche de cœur comprenant une résine de polycarbonate en couche de cœur, un additif ignifuge de cœur, et un additif d'opacité, et une couche de coiffe comprenant une résine de polycarbonate de couche de coiffe et un additif ignifuge de coiffe. La couche de cœur comprend une quantité suffisante d'additif ignifuge de cœur et la couche de coiffe comprend une quantité suffisante d'additif ignifuge de coiffe de telle sorte que l'article multicouche peut passer un test de densité de fumée tel qu'indiqué dans FAR 25.5, annexe F, partie V. Dans un mode de réalisation, un procédé de fabrication d'un article multicouche comprend : la formation d'une couche de cœur comprenant une résine thermoplastique de couche de cœur, et un additif ignifuge non bromé de cœur, et la formation d'une couche de coiffe comprenant une résine thermoplastique de couche de coiffe, un additif ignifuge non bromé de coiffe, et le thermoformage du film multicouche.
