    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： The invention provides foam forming methods that comprise: (a) preparing a foamable system comprising at least one hydrohaloolefin; and (b) ensuring either (i) the substantial absence of long-term decomposition-inducing contact between said hydrofluoroolefin and an amine-containing catalyst; (ii) that an effective amount of surfactant is available in the system under conditions which prevent long term exposure of the surfactant to a long-term decomposition reaction environment; or (iii) a combination of (i) and (ii). Related methods, foamable systems and foams are also disclosed. Preferred embodiments provide polyurethane and polyisocyanurate foams and methods for the preparation thereof, including closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The preferred foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are preferably produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, a catalyst and is further characterized by being substantially free of added water.
