Abstract: A process for preparing polyurethane integral skin foam with low ozone depletion potential, which comprises mixing 100 pph of a polyether polyol, 5-50 pph of a chain extender, 0.1-2.0 pph of a surfactant, 0.01-0.20 pph of an amine and 0.01-0.20 pph of an organotin catalyst, 0-3.0 pph of a nucleating agent and 1.0-30 pph of a blowing agent comprising 50 to 100 weight percent of HCFC-123 and 50 to 0 weight percent of HCFC-141b to form a polyol mixture; blending said polyol mixture with isocyanate having an ISO index=0.95 to 1.10 and reacting said blend at a temperature from 0.degree.-70.degree. C. in a mold at a temperature of from 10.degree. to 90.degree. C. for a molding time of 1 to 9 minutes to form a polyurethane integral skin foam, and the product of said process.
