摘要：
The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof More particularly, the invention relates to open-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 catalyst which is an adduct of an amine and an organic acid.
