  • Patent number: 6080799
    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.
