Title
(EN) A COMPOSITION FOR MANUFACTURING A POLYURETHANE FOAM
(FR) COMPOSITION POUR LA FABRICATION D'UNE MOUSSE DE POLYURÉTHANE
Abstract
(EN)
[Problem] Provided is a composition for manufacturing a polyurethane foam from which a polyurethane foam is obtainable having excellent adhesiveness to an adherend, particularly inorganic materials such as metal and olefinic resin materials such as polyethylene and polypropylene. [Solving means] To provide a composition for manufacturing a polyurethane foam, comprising a polyol and a polyisocyanate, wherein the polyol comprises at least two polyol compounds and one of said at least two polyol compounds is polycaprolactone, wherein the composition does not comprise 1-1dichloro-1-fluoroethane.
(FR)
Le problème décrit par la présente invention est de fournir une composition destinée à la fabrication d'une mousse de polyuréthane à partir de laquelle une mousse de polyuréthane peut être obtenue ayant une excellente adhésivité à une partie adhérée, en particulier des matériaux inorganiques comme le métal et des matériaux de résine oléfinique comme le polyéthylène et le polypropylène. La solution selon la présente invention concerne la fourniture d'une composition destinée à la la fabrication d'une mousse de polyuréthane, comprenant un polyol et un polyisocyanate, le polyol comprenant au moins deux composés de polyol et l'un desdits au moins deux composés de polyol étant de la polycaprolactone, la composition ne comprenant pas de 1-1dichloro-1-fluoroéthane.
