Zusammenfassung:A method for forming polyurethane foams in a molding apparatus includes a step of directing one or more polyol compositions into a mold. Each of the one or more polyol compositions include a polyol, water, and a catalyst. The method also includes a step of directing an isocyanate composition into the mold to form a foamed polyurethane. The isocyanate composition includes one or more isocyanates. The one or more polyol compositions and the isocyanate composition is combined into a reaction composition. Characteristically, water concentration is in a range from 1.5 to 2 percent of the weight of the total reaction composition and the amount of isocyanate in the reaction composition is in a sufficient amount such that the isocyanate index is from about 83 to 98. A molded component made by the method is also provided.
