摘要

Problem to be solved: to provide a foam comprising a low K factor value, a low global warming coefficient, a low molecular weight, a cost effectiveness, and a foaming agent exhibiting optimum performance over a wide temperature range.Solution: a thermosetting foam of independent air bubbles comprising a plurality of polymer cells and a foaming agent composition;The foaming agent composition(I)11444 - hexafluorobutene (1336 mzzm);And (II) 30-70 mol% trans-1-chloro-333 - containing TrifluoropropeneThe foam isThe initial K factor (BTU. Times. / time. Ft.ff. F) at 40. Deg.f below 0.14.Foam.No selection
