  • Patent number: 9688831
    Abstract: There is disclosed a phenol resin foam comprising a phenol resin, a hydrocarbon having 6 or less carbon atoms, and at least one halogenated hydroolefin selected from the group consisting of hydrofluoroolefins and hydrochlorofluoroolefins, and the phenol resin foam having the density of 10 kg/m3 or more and 150 kg/m3 or less, wherein the sum of the content of the hydrocarbon having 6 or less carbon atoms and the content of the hydrogenated hydroolefin is from 0.23 to 0.90 mol, the content of the hydrocarbon having 6 or less carbon atoms is from 0.03 to 0.85 mol, and the content of the halogenated hydroolefin is from 0.05 to 0.85 mol, per 22.4×10?3 m3 of spatial volume in the phenol resin foam.
