Process for manufacturing foam with improved wet set properties
High resilience polyurethane foams having improved wet set properties are obtained by reacting an isocyanate with a polyol component consisting of a polyoxyalkylene polyol with a functionality of 6 or more and a polymer polyol whose base polyol is a polyoxy-alkylene polyol with a functionality of 6...

| description | High resilience polyurethane foams having improved wet set properties are obtained by reacting an isocyanate with a polyol component consisting of a polyoxyalkylene polyol with a functionality of 6 or more and a polymer polyol whose base polyol is a polyoxy-alkylene polyol with a functionality of 6 or more, both polyols having oxyethylene caps in amounts of from 12 percent to about 30 percent based on the weights of the respective polyols, in the presence of an amine catalyst system. The resulting polyurethane foams are eminently suitable for seating cushions used in tropical or subtropical environments, may be prepared by a cold molding process, and may be used without an elevated temperature post cure. |
