Abstract
A process for making molded flexible polyurethane cellular products which do not substantially shrink or change dimensionally upon cooling is provided by exposing the curing product to atmospheric pressure while in the confines of the mold. Exposure can be accomplished by unlatching the mold or opening a port at an appropriate time after the reaction mixture was introduced into the mold so as to burst the cell walls of the polyurethane product.
