Title (EN) PROCESS FOR MAKING FLEXIBLE POLYURETHANE FOAM
(FR) PROCEDE POUR FABRIQUER DE LA MOUSSE DE POLYURETHANE SOUPLE
Abstract:
(EN) A process for making flexible polyurethane foam, employing a silicone surfactant composition containing 5 - 20 wt % of a defined low molecular weight silicone surfactant and 95 - 80 wt % of a defined high molecular weight silicone surfactant. Use of the claimed mixture of surfactants provides product foams having improved breathability relative to foams produced using high molecular weight silicone surfactant alone.
(FR) Procédé pour fabriquer de la mousse de polyuréthane souple, à l'aide d'une composition tensio-active siliconée contenant 5 à 20 % en poids d'un agent tensio-actif siliconé à faible masse molaire et 95 à 80 % en poids d'un agent tensio-actif siliconé à forte masse molaire. L'emploi du mélange d'agents tensio-actifs revendiqué donne des mousses ayant une respirabilité améliorée par rapport aux mousses produites seulement à l'aide d'un agent tensio-actif siliconé à forte masse molaire.
