| titleOfInvention | Pour-in-place flexible polyurethane foam articles |
| abstract | It has been discovered that a particular polyurethane formulation nmay be used to prepare "pour-in-place" (PIP) polyurethane foam narticles where the formulation is injected into a mold bearing an nexterior covering such as a fabric without the foaming liquid striking nthrough the layer. The formulation employs a hydrophilic polyhydric ncompound to help the reactivity balance that minimizes penetration of nthe exterior covering while also stabilizing the rising foam against shear ncollapse without excessively tightening the foam. Contrary to the nconventional expectation that the hydrophilic polyhydric compound nwould cause strike through problems since it delays the initial reaction ntime, it has been found to have the noted stabilizing effect. A preferred nhydrophilic polyhydric compound is glycerine. A preferred isocyanate nfor the formulation is tolylene diisocyanate (TDI), in contrast to ndiphenylmethane diisocyanate (MDI) heretofore used in PIP foams. |
