Zusammenfassung:This disclosure is directed to make low density and low amine emissions water blown polyurethane foams using a reactive catalyst composition. The method is particularly useful in the preparation of full water blown, low density polyurethane foams having a density in the range of about 6 to about 16 kg/m3. A catalyst composition comprising at least one non-emissive amine catalyst and tetraalkyl guanidine, the method of employing the catalyst composition and a formulation comprising the catalyst composition are disclosed.
