Abstract
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).
