<p>A flexible polyurethane foam formulation which is non-reactive at or near ambient temperatures is provided. The formulation comprises a polyisocyanate, a polyfunctional active hydrogen containing compound, an amine catalyst, a blowing agent and a polyether acid. The formulation which becomes reactive above 40 DEG C has the advantage, over similar systems based on formic acid, that the polyurethane foam is not tight and does not suffer from skin peeling.</p> |
