Claims27
A polyurethane foam composition comprising a blowing agent composition comprising carbon dioxide and from about 1% by weight to about 99% by weight of one compound in accordance with Formula I, wherein said one compound in accordance with Formula is the hydrochlorofluoroolefin trans-1,1,1-trifluoro-3-chloropropene (transHFCO-1233zd).
A polyurethane foam composition comprising a blowing agent composition consisting essentially of hydrochlorofluoroolefin trans-1,1,1-trifluoro-3-chloropropene (transHFCO-1233zd) and carbon dioxide.
A polyurethane foam composition comprising a blowing agent composition comprising one fluoroalkene wherein said fluoroalkene is the hydrochlorofluoroolefin trans-1,1,1-trifluoro-3-chloropropene (transHFCO-1233zd).
A polyurethane foam composition comprising a polymer blowing agent composition comprising carbon dioxide and the hydrochlorofluoro1olefin 1233zd wherein about 99 wt % or more of said hydrochlorofluoroolefin 1233zd is the trans stereoisomer of hydrochlorofluoroolefin 1233zd.
A polyurethane foam composition comprising a polymer blowing agent composition comprising carbon dioxide and the hydrochlorofluoro1olefin 1233zd wherein about 99 wt % or more of said hydrochlorofluoroolefin 1233zd is the trans stereoisomer of hydrochlorofluoroolefin 1233zd.
A polyurethane foam composition comprising a polymer blowing agent composition comprising the hydrochlorofluoro1olefin 1233zd wherein about at least about 70 wt % or more of said hydrochlorofluoroolefin 1233zd is the trans stereoisomer of hydrochlorofluoroolefin 1233zd.
A process of foaming a polyurethane foam comprising mixing polymer foam components with a foam blowing agent comprising the hydrochlorofluoroolefin 1233zd wherein about 70 wt % or more the hydrochlorofluoroolefin 1233zd is the trans stereoisomer of hydrochlorofluoroolefin 1233zd.
