| titleOfInvention | Oxynitrate additive for polyurethane foams |
| abstract | In a process for producing polyurethane foam by allowing a reaction mixture comprising at least one polyisocyanate component and at least one polyfunctional active hydrogen component to react, a compound selected from the group consisting of oxynitrate salts of metals of Group IV B of the Mendeleef periodic table, is employed as a cell opening additive. Such oxynitrate salts are also effective to modify tin tolerance of urethane formulations. The oxynitrate compounds are effective in both free rise and molded foam processes. Cell opening is accomplished, for instance, by reacting toluene diisocyanate with a polypropoxy/polyethoxy polyol in the presence of an oxynitrate salt of a Group IV B metal, such as zirconium oxynitrate, to form a foam having more open cells than a similar foam without oxynitrate. |
