Abstract:
1. A foam comprising a plurality of polymeric cells and a blowing agent composition comprising: from about 30 to about 70 mole percent 1,1,1,4,4,4-hexafluorobutene (1336mzzm); from about 30 to about 70 mole percent 1-chloro-3,3,3-trifluoropropene (1233zd); and optionally at least one adjuvant selected from the group consisting of co-blowing agent(s), polyol(s), surfactant(s), polymer modifier(s), colorant(s), dye(s), solubility enhancer(s), flammability suppressant(s), flame retardants(s), antibacterial agent(s), viscosity reduction modifier(s), filler(s), vapor pressure modifier(s), nucleating agent(s), catalyst(s) and combination of any two or more of these, wherein the foam exhibits an initial k-factor (BTU in/hr ft2° F.) at 40° F. of not greater than about 0.14.
