摘要

PPROBLEM TO BE SOLVED: To provide a light foamed molded product which is excellent in physical properties (flexibility, shock absorption, etc.), and fabricability while having low heat of combustion and suitability for incineration. PSOLUTION: The polyester resin composition comprises a polylactic acid resin, polymethyl methacrylate and a polyisocyanate compound. The effect is such that a cushioning-material for packing with a low heat of combustion is obtained by molding the resin composition in a particle state, impregnating a foaming agent into the particle and then foam-molding with a mold. Since the material has a property of spontaneous decomposition, its has a remarkably low environmental load. PCOPYRIGHT: (C)2003,JPO
