Title
(EN) A HIGH RESILIENCE POLYURETHANE FLEXIBLE FOAM
(FR) MOUSSE SOUPLE DE POLYURÉTHANE À HAUTE RÉSILIENCE
Abstract
(EN)
The present invention relates to a process for preparation of a high resilience polyurethane flexible foam and the high resilience polyurethane flexible foam prepared by the process, and use of the high resilience polyurethane flexible foam in car seat cushion or pillow. The high resilience polyurethane flexible foam is made from a reaction system comprising components such as isocyanate and polyol, and at least one amino terminated long-chain chain-extender, a blowing agent and a catalyst. The reaction system of the foam of the present invention has a rapid aging and a short mold-release time, and the obtained foam has good elasticity, high comfort and satisfactory low odor.
(FR)
La présente invention concerne un procédé de préparation d'une mousse souple de polyuréthane à haute résilience et la mousse souple de polyuréthane à haute résilience préparée par le procédé, et l'utilisation de la mousse souple de polyuréthane à haute résilience dans un coussin ou un oreiller de siège de voiture. La mousse souple de polyuréthane à haute résilience est fabriquée à partir d'un système réactionnel comprenant des constituants tels que de l'isocyanate et du polyol, et au moins un allongeur de chaîne à chaîne longue à terminaison amino, un agent gonflant et un catalyseur. Le système réactionnel de la mousse selon la présente invention présente un vieillissement rapide et un temps de démoulage court, et la mousse obtenue présente une bonne élasticité, un confort élevé et une faible odeur satisfaisante.
