POLYPROPYLENE RESIN FOAMED PARTICLES, IN-MOLD FOAM MOLDED BODY OF POLYPROPYLENE RESIN, AND METHOD FOR MANUFACTURING SAME

摘要

An in-mold foam molded body of polypropylene resin having high compressive strength while maintaining a low molding temperature during in-mold foam molding is obtained by using polypropylene resin foamed particles having an average bubble diameter of 100-340 μm, the polypropylene resin foamed particles comprising a base resin having a melting point of 140-150°C, the base resin including (i) a low-melting-point polypropylene resin A in which only a specific amount of structural units comprising 1-butene are present among all structural units and (ii) a high-melting-point polypropylene resin B.
