A nonflammable olefin thermoplastic elastomer composition (F) for use in skins of interior automotive trim, which comprises an oil-extended olefin thermoplastic elastomer composition (G), melamine-coated ammonium polyphosphate (h), a specified 1,3,5-triazine derivative, and a lubricant (f), wherein the composition (G) comprises an olefin thermoplastic elastomer composition (D) and a mineral oil (e), the composition (D) comprising 50 to 70% by weight of an ethylene/.alpha.-olefin copolymer elastomer (A) having a Mooney viscosity (ML1+4(100.degree. C.)) of 40 to 100, 35 to 21% by weight of a polypropylene resin (B) having a crystal melting point of 140.degree. to 165.degree. C. and an ethylene unit content of 1 to 2% by weight and 15 to 9% by weight of a low-density polyethylene resin (C) having a density of 0.90 to 0.93 g/cm.sup.3 and a crystal melting point of 102.degree.-118.degree. C.

Nonflammable olefin thermoplastic elastomer composition for use in skins

A process for preparing an open-cell structure from a vinyl chloride resin. The process includes mixing a vinyl chloride resin, stabilizer, plasticizer, surface active agent, azodicarbonamide and 4,4'-oxybisbenzenesulfonyl hydrazide to form a vinyl chloride resin paste. The vinyl chloride resin paste of step (a) is rendered alkaline, and mixed to form a uniformly-mixed paste. The paste is permitted to expand, and then heated to cause gelation.
