Abstract:
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 precipitation-resistant metal-based catalyst used alone or in combination with an amine catalyst.
Abstract:
The present invention relates to mixtures of 1,1,1,4,4,4-hexafluorobutene (1336mzzm) and 1-chloro-3,3,3-trifluoropropene (1233zd). The blends are useful as blowing agents for polymer foam, solvents, aerosol propellants and heat transfer media.
