PHENOL RESIN FOAM

摘要

A phenol resin foam which comprises a phenol resin, a hydrocarbon having six or fewer carbon atoms, and at least one halogenated hydroolefin selected from the group consisting of hydrofluoroolefins and hydrochlorofluoroolefins and which has a density of 10 to 150kg/m3, wherein the sum of contents of the hydrocarbon and the halogenated hydroolefin is 0.23 to 0.90mol, the content of the hydrocarbon is 0.03 to 0.85mol, and the content of the halogenated hydroolefin is 0.05 to 0.85mol, each content being per 22.4×10-3m3 of the space volume of the phenol resin foam.
