  The present invention relates to an improvement in flexible, semi-flexible and rigid foams formed by the catalytic reaction of an aromatic polyisocyanate, a polyol and a blowing agent and a process for preparing such polyisocyanate. The improvement resides in using an effective amount of a bismuth carboxylate or bismuth sulfonate having less than 34% free acid as the catalyst.

  Catalyst compositions for use in forming polyurethane products include a gelling catalyst, a trimerization catalyst, and a cure accelerator. The gelling catalyst is a tertiary amine, mono(tertiary amino) urea, bis(tertiary amino) urea, or a combination of any of these. Any known trimerization catalyst may be used. The cure accelerator may be a diol having at least one primary hydroxyl group, and having from five to 17 chain backbone atoms chosen from carbon, oxygen, or both between the hydroxyl groups, provided that at least five of the backbone atoms are carbon. Alternatively or in addition, the cure accelerator may be a polyol having three or more hydroxyl groups, at least two of which are primary, and having molecular weights between 90 g/mole and 400 g/mole. Delayed initiation of the polyurethane-forming reaction and/or reduced demold time for producing the polyurethane part can be obtained by using these catalyst compositions.

  用于形成聚氨酯产品的催化剂组合物包括胶凝催化剂、三聚催化剂和固化促进剂。胶凝催化剂是一种叔胺、单（叔氨基）脲、双（叔氨基）脲或其中任何一种的组合。也可使用任何已知的三聚催化剂。固化促进剂可以是具有至少一个伯羟基的二元醇，在羟基之间具有 5 至 17 个碳原子、氧原子或两者兼有的链骨架原子，但至少有五个骨架原子是碳原子。另外，固化促进剂可以是具有三个或三个以上羟基（其中至少两个是伯羟基）的多元醇，分子量在 90 克/摩尔到 400 克/摩尔之间。使用这些催化剂组合物可以延迟聚氨酯成型反应的开始时间和/或缩短生产聚氨酯 部件的脱模时间。
