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

This invention relates to compositions comprising 1,2-dichloro-1,2-difluoroethylene (i.e., CFO-1112) and an additional component. The compositions described herein may be useful, for example, in foam blowing applications.

Compositions comprising 1,2-dichloro-1,2-difluoroethylene for use in foam blowing applications

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 or extruding a foamable composition comprising (i) a compound selected from E-CHCl═CHCF, Z—CFCH═CHCF, and E-CFCH═CHCF, or any mixture thereof, and (2) a Chydrocarbon (e.g. cyclopentane), under conditions effective to form the foam.

Insulation performance foams

Disclosed is a mixture comprising the compound Z-1-chloro-2,3,3,3-tetrafluoroprop-1-ene and at least one additional compound selected from the group consisting of HFOs, HFCs, HFEs, CFCs, CO, olefins, organic acids, alcohols, hydrocarbons, ethers, aldehydes, ketones, and others such as methyl formate, formic acid, trans-1,2 dichloroethylene, carbon dioxide, cis-HFO-1234ze+HFO-1225yez; mixtures of these plus water; mixtures of these plus CO; mixtures of these trans 1,2-dichloroethylene (DCE); mixtures of these plus methyl formate; mixtures with cis-HFO-1234ze+CO; mixtures with cis-HFO-1234ze+HFO-1225yez+CO; mixtures with cis-HFO-1234ze+HFC-245fa; and azeotrope or azeotrope-like compositions. Also disclosed are methods of using the compositions as blowing agents, solvents, heat transfer compositions, aerosol propellant compositions, fire extinguishing and suppressant compositions.

Compositions and uses of Z-1-chloro-2,3,3,3-tetrafluoroprop-1-ene

The present invention provides a process comprising reacting polyisocyanate with active hydrogen-containing compound in the presence of Z-1,1,1,4,4,4-hexafluoro-2-butene at a temperature of at least 135&#xb0; F. (57.2&#xb0; C.) or a temperature of 135&#xb0; F. (57.2&#xb0; C.) to 150&#xb0; F. (65.6&#xb0; C.) to obtain as a result thereof, foamed reaction product, wherein the thermal conductivity of the foamed reaction product exhibits no appreciable change at any of the foaming temperatures within this range.
