Title (EN) POLYURETHANE FOAM
(FR) MOUSSE DE POLYURÉTHANE
Abstract:
(EN) A polyurethane foam is disclosed having unique load bearing characteristics rendering it suitable for a variety of applications. The foam exhibits high surface-softness and smoothness properties, making it well-suited for use in articles such as pillows and mattress toppers. However, upon continued application of pressure, the resilience of the foam increases sharply, translating into a remarkable support characteristics that make the foam suitable for use in the seat portions of chairs and sofas, as well as in the base portion of mattresses. The foams therefore address the limitations of conventional, high-resilience and visco-elastic polyurethane foams. A process of making the foam and its use in various articles is also disclosed.
(FR) L'invention concerne une mousse de polyuréthane possédant des caractéristiques de support de charge uniques, qui la rendent appropriée pour un grand choix d'applications. La mousse présente des propriétés de souplesse de surface et de lissé élevées, ce qui lui permet d'être bien adaptée à une utilisation dans des articles tels que des oreillers et des couvre-matelas. Cependant, lors de l'application continue d'une pression, l'élasticité de la mousse augmente brusquement, ce qui se traduit par des caractéristiques de soutien remarquables qui permettent à la mousse d'être appropriée pour une utilisation dans les parties de siège de chaises et de sofas, ainsi que dans la partie de base de matelas. Les mousses résolvent donc les limitations des mousses de polyuréthane viscoélastiques et à résilience élevée classiques. L'invention concerne également un procédé de fabrication de la mousse et son utilisation dans divers articles.
