  • Patent number: 4938819
    Abstract: A method of making a foam product including the steps of reacting an isocyanate component with a polyol component and foaming with a foaming agent to form a self-supporting intermediate foam material. The isocyanate component is present in excess of a stoichiometric quantity needed to react with the polyol component. The self-supporting intermediate foam material is then contacted with water and the self-supporting, intermediate foam material is heated to form a foam product, the water reacting with the remaining unreacted isocyanate component. The self-supporting, intermediate foam material formed by the first foaming step is rigid or semi-rigid at room temperature but it can be softened by heating to enable it to be used for deep draw molding in a successive cure molding process without cracking, splitting or being destroyed.
