A process for producing an open cell foam comprising the steps of: (a) forming a compound comprising polyvinyl chloride resin produced by suspension polymerization, at least one organic stabilizer containing at least one Group I metal and at least one organic stabilizer containing at least one Group II metal, at least one surface active agent, and a heat decomposable blowing agent; and (b) heating the compound to decompose the blowing agent thereby producing the foam. A foamable compound comprising polyvinyl chloride resin produced by suspension polymerization, at least one organic stabilizer containing at least one Group I metal and at least one organic stabilizer containing at least one Group II metal, at least one surface active agent, and a heat decomposable blowing agent. The foam formed exhibits high breathability as well as a high water permeability when desired.
