摘要： 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 polyoxyalkylene 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.

摘要翻译： 通过使异氰酸酯与官能度为6以上的聚氧化烯多元醇组成的多元醇成分和基础多元醇为6以上的聚氧化烯多元醇的聚合物多元醇反应，得到具有改善的湿定型性能的高弹性聚氨酯泡沫， 在胺催化剂体系的存在下，基于相应多元醇的重量，两种多元醇的含量为12％至约30％。 得到的聚氨酯泡沫特别适用于在热带或亚热带环境中使用的座垫，可以通过冷成型方法制备，并且可以在没有高温后固化的情况下使用。

摘要： 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.degree. 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.
