<p>Process For Rapid Curing of Polyether Polyurethane Foam A process for the rapid post curing of polyether polyurethane foam in the form of porous blocks in which the foam is subjected to a mixture of water vapor and gaseous ammonia, primary or secondary amines at a temperature of about 50 to 150.degree.F. For a period of 1 or more minutes. The cured foam recovers its original dimensions when distorted or compressed after the distortion or compression force is released.</p> |
