Zusammenfassung:	PURPOSE: An Interior form for vehicles is provided to improve sound absorbability maintaining physical strength by increasing the content of bipolyol and vermiculite, thereby suitable for interior material of vehicles. CONSTITUTION: An Interior form for vehicles comprise a 1-4 parts by weight surfactant, a 1-2 parts by weight amine catalyst, a 10-20 parts by weight vermiculite, a 1-3 parts by weight foaming agent, and 50-100 parts by weight isocyanate comparison to 100 parts by weight polyol. A manufacturing method thereof comprises: a step manufacturing urethane foam by mixing the polyol, the surfactant, the amine catalyst, the vermiculite, and the isocyanate to a mold; a step de-molding the form; and a step drying the foam.
