<p><P>PROBLEM TO BE SOLVED: To provide a polylactic acid foamed particle molding excelling in mutual fusing property of polylactic acid foamed particles, dimensional stability, appearance and mechanical material property. <P>SOLUTION: The polylactic acid foamed particle molding is a foamed particle molding obtained by molding, in a die, foamed particles formed of polylactic acid containing at least 50 mol% of lactic acid units. The difference (ΔH<SB>endo:Mold</SB>-ΔH<SB>exo:Mold</SB>) between an endothermic calorific value (ΔH<SB>endo:Mold</SB>) and an exothermic calorific value (ΔH<SB>exo:Mold</SB>) in heat flux scanning differential calorimetry of the foamed particle molding is at least 14 J/g, and the ratio (A/B) of flexural strength (A: N/cm<SP>2</SP>) of the foamed particle molding and the density (B: g/cm<SP>3</SP>) of the foamed particle molding is at least 294 (N×cm/g). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
