A blowing agent for thermosetting foams is disclosed. The blowing agent is predominately the trans isomer of the hydrochlorofluoroolefin (HCFO) HFCO-1233zd alone or in combination with a hydrofluoroolefin (HFO), hydrofluorocarbon (HFC), hydrochlorofluoroolefin (HCFO), a hydrocarbon. The blowing agen
A blowing agent for thermosetting foams is disclosed. The blowing agent is predominately the trans isomer of the hydrochlorofluoroolefin (HCFO) HFCO-1233zd alone or in combination with a hydrofluoroolefin (HFO), hydrofluorocarbon (HFC), hydrochlorofluoroolefin (HCFO), a hydrocarbon. The blowing agent is effective as a blowing agent in the manufacture of thermosetting foams.
