The present invention relates to polyol compositions which can be used to produce dimensionally stable, low density water-blown rigid foams which have acceptable compressive strengths and acceptable k-factors. In one embodiment of the present invention, the polyol compositions are composed of at least one aromatic amine-initiated polyether polyol and at least one polyether polyol having a functionality greater than or equal to 2.5 in which at least 50% by weight of the polyol composition is aromatic amine- initiated polyether polyol and in which no more than 50% by weight of the polyol composition is polyether polyol having a functionality greater than or equal to 2.5. In another embodiment of the present invention, the polyol compositions are composed of at least one aromatic amine-initiated polyether polyol and at least one polyester polyol in which at least 30% by weight of the polyol composition is aromatic amine-initiated polyether polyol and in which no more than 70% by weight of the polyol composition is polyester polyol.

L'invention concerne des compositions de polyol pouvant être utilisées afin de produire des mousses rigides de dimensions stables, basse densité, soufflées par eau présentant des résistances à la compression et des facteurs k acceptables. Dans un mode de réalisation, ces compositions de polyol contiennent au moins un polyol de polyéther aromatique à départ amine et au moins un polyol de polyéther dont la fonctionnalité est supérieure ou égale à 2,5, au moins 50 % en poids de cette composition de polyol consistant en polyol de polyéther aromatique à départ amine et 50 % en poids maximum de cette composition de polyol consistant en polyol de polyéther possédant une fonctionnalité supérieure ou égale à 2,5. Dans un autre mode de réalisation, ces compositions de polyol contiennent au moins un polyol de polyéther aromatique à départ amine et au moins un polyol de polyester, au moins 30 % en poids de cette composition de polyol consistant en polyol de polyéther aromatique à départ amine et 70 % en poids maximum de cette composition consistant en polyol de polyester.
