ABSTRACT The invention relates to low density cellular, rigid polyurethanes which employ the dimethyl esters of adipic, glutaric and succinic acids and mixtures thereof in conjunction with nonylphenol as cell-opening agents. The use of this ester phenol mixture obviates the need of other surfactants, particularly silicone surfactants which reduce the adhesion of the urethanes to fabrics in pour-behind-fabric applications.
