EXPANDABLE PHENOLIC RESIN COMPOSITION, PHENOLIC RESIN FOAM, AND METHOD FOR PRODUCING THE PHENOLIC RESIN FOAM

摘要

There is provided an expandable phenolic resin composition
comprising: a phenolic resin; an acid curing catalyst for the resin; a
foaming agent; and a surfactant, wherein the foaming agent comprises a
hydrocarbon-based foaming agent; and the surfactant is a
polyoxyethylene alkyl ether having an alkyl ether moiety having 14 to
22 carbon atoms, and the content of the surfactant is 0.01 to 10 parts by
weight relative to 100 parts by weight of the phenolic resin.
