    • The present invention provides a waterproof plastic foam such as waterproof polyurethane foam which can keep the inherent properties of the foam and exhibit low gas permeability and water absorption, excellent water-sealing properties and hence a stable waterproofness. A waterproof plastic foam obtained by a process which comprises foaming a foamable composition comprising a polyisocyanate, a compound containing at least two active hydrogen groups, a compound containing at least one ester bond, a catalyst, a blowing agent and a foam stabilizer, and then curing the foam is described, wherein the compound containing at least one ester bond is a product of the reaction of any one of a monocarboxylic acid having not less than 9 carbon atoms, an aliphatic dicarboxylic acid having not less than 8 carbon atoms and an alicyclic dicarboxylic acid having not less than 8 carbon atoms with a monoalcohol having not less than 10 carbon atoms, and the compound containing at least one ester bond is incorporated in an amount of from 7 to 100 parts by weight based on 100 parts by weight of the compound containing at least two active hydrogen groups. A waterproof plastic foam obtained by a process which comprises foaming a foamable composition comprising a polyisocyanate, a compound containing at least two active hydrogen groups, a compound containing ester bonds, a catalyst, a blowing agent and a foam stabilizer, and then curing the foam is also described, wherein the compound containing ester bonds is made of oleic acid and one component selected from the group consisting of butadiene polyol, adduct of bisphenol A with propylene oxides and castor oil, and the compound containing ester bonds is incorporated in an amount of from 7 to 100 parts by weight based on 100 parts by weight of the compound containing at least two active hydrogen groups.
