ABSTRACT:
An expandable vinyl chloride resin composition for foaming under atmospheric pressure which comprises a resin ingredient comprising (A) a vinyl chloride homopolymer or copolymer having substantially no active hydrogens, (B) a vinyl chloride copolymer having active hydrogens and (C) a thermoplastic polyurethane resin, and a crosslinking agent, a foaming agent, a thermal stabilizer and a plasticizer, the ratio of the components (A), (B) and (C) being 30 to 90:5 to 40:5 to 40 by weight. The composition is expanded under atmospheric pressure to give a foam of a high expansion ratio which has uniform and fine cells and shows an excellent rubber-like elasticity.
