Title
(DE) TRANSLUZENTE POLYURETHANSCHAUMSTOFFE
(EN) TRANSLUCENT POLYURETHANE FOAMS
(FR) MOUSSES DE POLYURÉTHANE TRANSLUCIDES
Abstract
(DE)
Die vorliegende Erfindung betrifft spezifische transluzente, bevorzugt lichtechte, Polyurethan- Schaumstoffe, die eine hohe Li chttransmi s sion besitzen und daher z.B. für die Herstellung von transluzenten Polyurethanschaumstoffen oder Mehrschichtverbundelementen beispielsweise zur Herstellung von Bauelementen, insbesondere als Dachelemente wie Lichtbändern und Lichtkuppeln, als Wandelement wie ein Paneel, in Fahrzeugen, in Lampen, als Möbel, als Trennwände und in Sanitäreinrichtungen, geeignet sind.
(EN)
The present invention relates to specific translucent, preferably lightfast, polyurethane foams which have a high light transmission and are therefore suitable e.g. for producing translucent polyurethane foams or multilayer composite elements, for example for producing structural components, more particularly as roof elements such as strip lights and light domes, as wall elements such as a panel, in vehicles, in lamps, as furniture, as partitions and in sanitary facilities.
(FR)
La présente invention concerne des mousses de polyuréthane translucides spécifiques, de préférence stables à la lumière, qui présentent un facteur élevé de transmission de la lumière et donc conviennent par exemple à la fabrication de mousses de polyuréthanne translucides ou d'éléments composites multicouches, par exemple pour la fabrication d'éléments de construction, en particulier en tant qu'éléments de toit tels que des bandes vitrées et des coupoles translucides, en tant qu'éléments muraux tels qu'un panneau, dans des véhicules, dans des lampes, en tant que meubles, en tant que parois de séparation et dans des installations sanitaires.
