Abstract
Official abstract text for this publication.
A blowing agent for thermosetting foams is disclosed. The blowing agent is a hydrofluoroolefin (HCFO), preferably HFCO-1234yf in combination with a hydrochlorofluoroolefin (HCFO) preferably one selected from HCFO-1233zd, HCFO-1223, HCFO-1233xf and mixtures thereof. The blowing agent is effective as a blowing agent in the manufacture of thermosetting foams.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polymer blowing agent composition for thermosetting foams comprising (a) from 20 to 50 weight % HFO-1234yf in combination with (b) from 50 to 80 weight % of the hydrochlorofluoroolefin HCFO-1233zd. 2. The polymer blowing agent composition of claim 1 , further comprising a non-HFO and non-HCFO hydrofluorocarbon. 3. The polymer blowing agent composition of claim 2 wherein said non-HFO and non-HCFO hydrofluorocarbon is selected from the group consisting of difluoromethane (HFC32); 1,1,1,2,2-pentafluoroethane (HFC125); 1,1,1-trifluoroethane (143a); 1,1,2,2-tetrafluoroethane (HFC134); 1,1,1,2-tetrafluoroethane (HFC134a); 1,1-difluoroethane (HFC152a); 1,1,1,2,3,3,3-heptafluoropropane (HFC227ea); 1,1,1,3,3-pentafluoropropane (HFC245fa); 1,1,1,3,3-pentafluorobutane (HFC365mfc) and 1,1,1,2,2,3,4,5,5,5-decafluoropentane (HFC4310mee). 4. The polymer blowing agent composition of claim 1 , further comprising a second hydrofluoroolefin selected from the group consisting of tetrafluoropropenes; trifluoropropenes; tetrafluorobutene isomers; pentafluorobutene isomers; hexafluorobutene isomers; heptafluorobutene isomers; heptafluoropentene isomers; octafluoropentene isomers and nonafluoropentene isomers. 5. The polymer blowing agent composition of claim 1 further comprising a component selected from the group consisting of a second hydrofluoroolefin (HFO), a hydrofluorocarbon, a hydrocarbon, an alcohol, an ester, an aldehyde, a ketone ether/diether, carbon dioxide and mixtures thereof. 6. The polymer blowing agent composition of claim 1 , further comprising a second hydrofluoroolefin selected from the group consisting of HFO-1234ze; HFO-1243zf, HFO-1354; HFO-1345; HFO-1336; HFO-1327; HFO-1447; HFO-1438 and HFO-1429.
