Title (EN) PROCESS FOR THE PREPARATION OF A POLYURETHANE FOAM
(FR) PROCÉDÉ POUR LA PRÉPARATION D'UNE MOUSSE DE POLYURÉTHANE
Abstract:
(EN) The present invention relates to processes for the preparation of a polyurethane foam or a modified polyurethane foam by contacting an A-side composition comprising at least one polyol and at least one chemical compound capable of releasing a blowing agent by thermally- and/or chemically-induced decomposition with a B-side composition comprising at least one isocyanate comprising a step wherein the A-side and/or the B-side composition have a high viscosity.
(FR) La présente invention concerne des procédés de préparation d'une mousse de polyuréthane ou d'une mousse de polyuréthane modifiée par mise en contact d'une composition de côté A comprenant au moins un polyol et au moins un composé chimique capable de libérer un agent de soufflage par décomposition thermiquement et/ou chimiquement induite avec une composition de côté B comprenant au moins un isocyanate comprenant une étape dans laquelle le côté a et/ou la composition du côté B ont une viscosité élevée.
