Title
(EN) RIGID POLYURETHANE FOAMS
(FR) MOUSSES RIGIDES DE POLYURETHANNE
Abstract
(EN)
Process for preparing a rigid polyurethane or urethane-modified polyisocyanurate foam in the absence of a silicone-based surfactant wherein the polyfunctional isocyanate-reactive composition comprises an amine-initiated polyether polyol and optionally a polyether polyol of functionality 2 to 6 and number average molecular weight between 1000 and 10000 and wherein optionally the polyisocyanate composition comprises the reaction product of a stiochiometric excess of an organic polyisocyanate and a substantially fluorinated isocyanate-reactive compound.
(FR)
On décrit un procédé de préparation d'une mousse rigide de polyisocyanurate modifié par polyuréthanne ou uréthanne, en l'absence d'un tensioactif à base de silicone, dans lequel la composition réagissant à l'isocyanate polyfonctionnel comprend un polyol de polyéther amorcé par une amine et, éventuellement, un polyol de polyéther possédant une fonctionnalité de 2 à 6 et un poids moléculaire moyen en nombre compris entre 1000 et 10000, et dans lequel la composition de polyisocyanate comprend le produit de réaction d'un excès stoechiométrique d'un polyisocyanate organique et d'un composé réagissant à l'isocyanate et sensiblement fluoré.
