POLYURETHANE OR POLYISOCYANURATE FOAMS BLOWN WITH HYDROFLUOROCARBONS AND CARBON DIOXIDE

Rigid polyurethane or polyisocyanurate foams are produced by reacting an organic polyisocyanate with an amine-based polyether polyol in the presence of a catalyst, a hydrogen-containing fluorocarbon, water and carbon dioxide. L'invention concerne des mousses de polyuréthanne ou de polyisocyanur...

Beschreibung
Zusammenfassung:	Rigid polyurethane or polyisocyanurate foams are produced by reacting an organic polyisocyanate with an amine-based polyether polyol in the presence of a catalyst, a hydrogen-containing fluorocarbon, water and carbon dioxide. L'invention concerne des mousses de polyuréthanne ou de polyisocyanurate rigides produites par mise en réaction d'un polyisocyanate organique avec un polyol de polyéther à base d'amine en présence d'un catalyseur, d'un fluorocarbure contenant de l'hydrogène, d'eau et de dioxyde de carbone.
