Abstract (en)
[origin: WO8303415A1] A method of manufacturing a polyurethane foam that comprises blending an isocyanate with a polyol and a catalyst. The catalyst adds to the hydroxyl content of the blend and thereby permits a reduction in the amount of polyol required to produce a given amount of the foam.
