A pre-polymer comprising: isocyanate, polyol, oil, and an amine catalyst and an associated method for producing a polyurethane bonded foam product. The method comprises: coating a plurality of foam pieces with the pre-polymer; compressing the foam pieces into a foam log of a desired density; and steaming the foam log to cure the pre-polymer. Preferably, the amine catalyst is dimorpholinodiethylether (DMDEE) and the isocyanate, the polyol, and the oil are present in the pre-polymer in about equal amounts.
