    Abstract: A method for the production of polyurethane foams and of thermoplastic foams is described. As blowing agent, a composition is used, which contains or consists of pentafluorobutane, preferably pentafluorobutane (HFC-365mfc) and at least one further blowing agent selected from the group comprising; difluoromethane (HFC-32); difluoroethane, preferably 1,1-difluoroethane (HFC-152a); 1,1,2,2-tetrafluoroethane (HFC-134); 1,1,1,2-tetrafluoroethane (HFC-134a); hexafluoropropane, preferably 1,1,1,3,3,3-hexafluoropropane (HFC-236fa); 1,1,2,3,3,3-hexafluoropropane (HFC-236ea) and heptafluoropropane, preferably 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), low-boiling, optionally halogenated hydrocarbons and/or low-boiling, optionally halogenated ethers.

    Abstract: Mixtures containing 50 to 99% by weight of 1,1,1,3,3-pentafluorobutane and 1 to 50% by weight of at least one fluorohydrocarbon selected from 1,1,1,2-tetrafluoroethane, 1,1,1,3,3-pentafluoropropane, 1,1,1,3,3,3-hexafluoropropane, and 1,1,1,2,3,3,3-heptafluoropropane. The mixtures are extremely well suited for use as foaming gases for a blowing agent to produce foamed plastic materials, particularly polyurethane foams. The mixtures are not combustible and exhibit improved insulating properties, particularly when used at low temperatures.
