Abstract
The present invention provides compositions comprising pentafluoropropane, a second component selected from the group consisting of decafluoropropane, perfluorobutyl methyl ether and combinations of these, and a third component selected from the group consisting of methanol, 1,2-trans-dichloroethylene and combinations of these. The present invention further provides for refrigerants, blowing agents, foam compositions, polyol premixes, closed-cell foams, sprayable compositions, and the like, comprising the present compositions.
