The present invention includes polymer interlayers that are used in multiple layer glazing panels. Interlayers of the present invention comprise a thermoplastic polymer, a plasticizer, a tungsten oxide agent, and a stabilizing agent that prevents the degradation of the tungsten oxide agent. Interlayers incorporating such components have improved ultraviolet light blocking character, and also maintain optical quality over time.
La présente invention se rapporte à des couches intermédiaires polymères utilisées dans la fabrication de panneaux vitrés multicouches. Les couches intermédiaires de la présente invention comprennent un polymère thermoplastique, un plastifiant, un agent d'oxyde de tungstène, et un agent stabilisant qui empêche la dégradation de l'agent d'oxyde de tungstène. Des couches intermédiaires comprenant ce type de composants possèdent une caractéristique de blocage de la lumière ultraviolette améliorée et conservent également leurs qualités optiques sur la durée.
