Abstract:
Provided are foam blowing agents comprising one or more chlorofluoroolefins selected from 1,2-dichloro-1,2-difluoroethene, 3,3-dichloro-3-fluoropropene, 2-chloro-1,1,1,3,4,4,4-heptafluoro-2-butene, and 2-chloro-1,1,1,4,4,4-hexafluoro-2-butene, as well as foams produced therefrom.
Abstract:
Disclosed are bowing agent compositions, foamable compositions, foams, foaming methods and/or foamed articles comprising one or more C2 to C6 fluoroalkenes, more preferably one or more C3 to C5 fluoroalkenes, and even more preferably one or more compounds having Formula I as follows: XCFzR3-z (I) where X is a C1, C2, C3, C4, or C5 unsaturated, substituted or unsubstituted radical, each R is independently Cl, F, Br, I or H, and z is 1 to 3, it generally being preferred that the fluoroalkene of the present invention has at least four (4) halogen substituents, at least three of which are F and even more preferably none of which are Br.
Abstract:
Various uses of fluoroalkenes, including tetrafluoropropenes, particularly (HFO-1234) in a variety of applications, including as blowing agents are disclosed.
Abstract:
The instant invention relates to compositions comprising a blend 1-chloro-3,3,3-trifluoropropene (HCFO 1233zd) and 1,1-dichloro-1-fluoroethane (HCFC 141b). In particular, the instant invention relates to blowing agents and foamable compositions containing at least such a blend, as well as solvents containing such a blend.
Abstract:
A composition which is a blowing agent which comprises from about 75% to about 90% by weight trans-1,3,3,3-tetrafluoropropene, from about 1% to about 15% by weight cis-1,3,3,3-tetrafluoropropene, and from about 1% about 15% by weight 1,1,3,3,3-pentafluoropropane.
Abstract:
A heat transfer system and method for controlling heat transfer to and from a container having thermal insulation disposed with respect to said container or compartment so as to inhibit the flow of heat into and/or out of the compartment, said insulation comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a haloalkene according to Formula IA: where each R is independently Cl, F, H, or CF3, provided that the total number of carbon atoms is either 3 or 4, R' is (CR2)nY, Y is CF3 and n is 0 or 1; and a heat transfer system for adding and/or removing heat from the compartment or container by use of a heat transfer fluid comprising a haloalkene Formula IB: where each R is independently Cl, F or H R' is (CR2)nY, Y is CF3 and n is 0 or 1.
