POLYLACTIC ACID-BASED RESIN FOAMED PARTICLE FOR FOAM MOLDING IN MOLD, SECONDARY FOAMED PARTICLE, AND POLYLACTIC ACID-BASED RESIN FOAMED MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide polylactic acid-based resin foamed particles for foam molding in mold, from which a polylactic acid-based resin foamed molded article is formed by a foam molding in the mold. SOLUTION: The polylactic acid-based resin foamed particles for foam molding in the mold is obtained by cutting a polylactic acid-based resin extruded product which is formed by extruding and foaming a predetermined polylactic acid-based resin, into particles. In a DSC curve obtained by heat flux differential scanning calorimetry of the polylactic acid-based resin foamed particles for foam molding in the mold, the DSC curve has an endothermic peak curve and an exothermic peak curve continuous with the endothermic peak curve at 40-120°C and an endothermic heat value (ΔHe) at 40-120°C is 1-20 J/g, and has an exothermic peak curve and an endothermic peak curve continuous with the exothermic peak curve at 120-200°C and an endothermic heat value (ΔHm) at 120-200°C is 25 J/g or more.
