摘要：
The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a non-amine catalyst used alone or in combination with an amine catalyst.
摘要（中）：
本发明提供聚氨酯和聚异氰脲酸酯泡沫及其制备方法。 更具体地说，本发明涉及闭孔，聚氨酯和聚异氰脲酸酯泡沫及其制备方法。 泡沫的特征在于细小的均匀的细胞结构和很少或没有泡沫崩溃。 泡沫体是用多元醇预混物组合物生产的，该组合物包含氢卤烯烃发泡剂，多元醇，硅氧烷表面活性剂和单独使用或与胺催化剂组合使用的非胺催化剂的组合。
