The present application provides foams having improved insulation and thermal performance and processes of forming said foams. Exemplary foams described herein are prepared according to a process comprising reacting a foamable composition comprising a blowing agent and one or more nucleating agents, under conditions effective to form the foam.

Nucleating agents for PIR foams

The present application provides binary azeotrope or azeotrope-like compositions comprising perfluoroheptene and an additional component, wherein the additional component is present in the composition in an amount effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene. Methods of using the compositions provided herein in cleaning and carrier fluid applications are also provided.

Binary azeotrope and azeotrope-like compositions comprising perfluoroheptene

The present application provides compositions comprising 1,2-dichloro-1,2-difluoroethylene (i.e., CFO-1112) and, optionally, an additional component. The present application further provides use of the compositions provided herein in cleaning, solvent, carrier fluid, and deposition applications.

Compositions comprising 1,2-dichloro-1,2-difluoroethylene for use in cleaning and solvent applications

The present application provides azeotrope or azeotrope-like compositions comprising dimethyl carbonate and a perfluoroheptene ether or a perfluoropentene ether, wherein the perfluoroheptene ether or perfluoropentene ether is present in the composition in an amount effective to form an azeotrope composition or azeotrope-like composition with the dimethyl carbonate. Methods of using the composition provided herein in cleaning and carrier fluid applications are also provided.

Azeotropic compositions comprising dimethyl carbonate and perfluoroalkene ethers

Disclosed are compositions comprising 90 to 99 weight percent trans-1,2-dichloroethylene, from 0.1 to 8 weight percent methylperfluoroheptene ethers and from 0.5 to 2.0 weight percent of a fluorocarbon selected from the group consisting of Z-1,1,1,4,4,4-hexafluoro-2-butene, 1,3,4,4,4-pentafluoro-3-trifluoromethy-1-butene, 1,1,1,4,4,5,5,5-octafluoro-2-pentene, perfluorobutyl methyl ether, perflurobutyl ethyl ether, perfluoroisopropylmethyl ether, perfluoroethyl isopropyl ketone, heptafluorocyclopentane, and E-1,1,1-trifluoro-3-chloro-2-propene, wherein the composition is non-flamable. The disclosure further provides a method for removing residue from a surface of an article comprising: (a) contacting the article with a composition comprising a composition of MPHE, trans-1,2-dichloroethylene and a fluorocarbon selected from the group consisting of Z-1,1,1,4,4,4-hexafluoro-2-butene, 1,3,4,4,4-pentafluoro-3-trifluoromethy-1-butene, 1,1,1,4,4,5,5,5-octafluoro-2-pentene, perfluorobutyl methyl ether, perflurobutyl ethyl ether, perfluoroisopropylmethyl ether, perfluoroethyl isopropyl ketone, heptafluorocyclopentane, and E-1,1,1-trifluoro-3-chloro-2-propene; and (b) recovering the surface from the composition.
