Abstract Foamable waterborne dispersions which form stable flexible foams under ambient cure conditions are disclosed, said foamable waterborne dispersions comprising: a polyurethane polymer formed from one or more aliphatic or cycloaliphatic polyisocyanate and at least two different polymeric polyol components selected from polyether polyol, polyester polyol, and polycarbonate polyol; wherein the ambient cure conditions include a temperature of from 4 °C to 32 °C, and a humidity of 0% relative humidity to 90% relative humidity. Also disclosed are the flexible foams produced from the foamable waterborne dispersions, as well as methods of providing a space filling layer or space filling volume adjacent to or on a surface, said methods comprising applying to said surface a foamed sample of the foamable waterborne dispersions, and allowing the foamed sample of foamable waterborne dispersion to dry under ambient conditions to yield a stable flexible foam.. L'invention concerne des dispersions aqueuses expansibles qui forment des mousses flexibles et stables dans des conditions de durcissement ambiantes, lesdites dispersions aqueuses expansibles comprenant : un polymère de polyuréthane formé à partir d'un ou plusieurs polyisocyanates aliphatiques ou cycloaliphatiques et d'au moins deux composants polyols polymères différents sélectionnés parmi le polyéther polyol, le polyester polyol et le polycarbonate polyol ; les conditions de durcissement ambiantes comprenant une température allant de 4 °C à 32 °C, et une humidité de 0 % d'humidité relative à 90 % d'humidité relative. L'invention concerne également les mousses souples produites à partir des dispersions aqueuses expansibles, ainsi que des procédés de fourniture d'une couche de remplissage d'espace ou d'un volume de remplissage d'espace adjacent à ou sur une surface, lesdits procédés comprenant l'application sur ladite surface d'un échantillon expansé des dispersions aqueuses expansibles, et permettant à l'échantillon expansé de dispersion aqueuse expansible de sécher dans des conditions ambiantes pour produire une mousse souple stable.
