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 non-amine catalyst used alone or in combination with an amine catalyst.

Abstract: The present invention relates to building envelopes and methods of forming a building envelope comprising foams having a polymeric foam structure including a plurality of closed cells therein and trans-1-chloro-3,3,3-trifluoropropene (1233zd(E)) contained in at least a portion of said cells.

Abstract: The present invention relates to mixtures of 1,1,1,3,3,3-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.

Abstract: A method of forming foam comprising: (a) providing at least a first relatively high pressure liquid comprising a first reactive component; (b) introducing into said relatively high pressure stream a liquid blowing agent composition comprising 1,3,3,3-tetrafluoropropene (HFO-1234ze) and/or HFCO-1233zd to produce a second stream at relatively high pressure and containing said blowing agent; and (c) mixing at least a portion of said third stream with a fourth stream containing a component reactive with said first component to produce a mixed reactive stream.

Abstract: 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.

Abstract: A method for insulating a polymeric fabric of a shelter which comprises: applying a fabric material (e.g., a natural fabric) to at least a portion of the polymer fabric; and applying an insulation material to the natural fabric opposite to the polymer fabric or treating the polymeric fabric to allow for direct application of the insulation material. The surface treatment is either roughing, electrostatic surface treatment, chemical surface treatment, primers, adhesives, solvents, or other coatings to enhance adhesion to the insulation material.
