BLOWING AGENT COMPOSITIONS OF CARBON DIOXIDE AND HYDROCHLOROFLUOROOLEFINS

The present invention relates to blowing agent compositions of carbon dioxide and at least one hydrochlorofluoroolefin (HCFO). The HCFOs can include, but are not limited to, 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) and mixtures thereof. The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor made from thermoplastic resins The blowing agent compositions may also optionally include one or more hydrofluoroolefins (HFOs).
