The present invention provides rigid polyurethane foams prepared by mixing an isocyanate with a polyol component containing an aromatic amine~initiated polyether polyol, an aromatic polyester polyol and optionally, a sucrose-based polyether polyol. The inventive foams have good properties as indicated by an initial k-factor at 35~F of from about 0.115 to about 0.120 BTU-in./hr. ft2 ~F and may find use as insulation materials in the construction and refrigeration industries.

La présente invention se rapporte à des mousses de polyuréthanne rigides obtenues par mélange d'un isocyanate et d'un constituant polyol contenant un polyol de polyéther amorcé par une amine aromatique, un polyol de polyester aromatique et, éventuellement, un polyol de polyéther à base de saccharose. Les mousses selon l'invention présentent de bonnes caractéristiques telles qu'un coefficient K initial à 35 ·F d'environ 0,115 à environ 0,120 BTU-pouce/heure.pied?2 ¿·F et peuvent être utilisées comme matériaux d'isolation dans les industries du bâtiment et de la réfrigération.
