More Information
Summary:This invention relates to thermoset, thermally insulating panel and spray foams having desirable and unexpectedly low thermal conductivities, and to compositions, methods and systems which use and/or are used to make such foams. In particular is dislosed a method comprising: (a) providing a thermosetting foam forming component and a blowing agent for forming predominantly closed cells in the foam, wherein the blowing agent comprises cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzzm(Z)) and water, with (i) the HFO-1336mzzm(Z) and water in the blowing agent together comprising at least about 50% by weight of the total of all components in the blowing agent, and (ii) the weight ratio of HFO-1336mzzm(Z) to water in the blowing agent being from about 90:10 to less than 98:2, and (b) forming a foam from said provided foamable composition.
