| titleOfInvention | Polypropylene resin expanded particles and molded articles thereof |
| abstract | It is possible to obtain a polypropylene resin expanded resin molded article having equivalent properties by molding in a mold at a low heating temperature without impairing the excellent properties such as compression properties and heat resistance, which are characteristics of the polypropylene resin expanded particles. An object of the present invention is to provide an excellent expanded polypropylene resin particle. The present invention is a polypropylene resin expanded particle comprising a polypropylene resin having a resin melting point of 115 to 135 ° C. and an Olsen bending elastic modulus of 500 MPa or more, and the amount of ash on the surface of the expanded particle is 3000 ppm by weight or less ( The foamed particles are obtained when the polypropylene resin foamed particles 1 to 3 mg are heated from room temperature to 200 ° C. at a temperature rising rate of 10 ° C./min by a differential scanning calorimeter. In the first DSC curve, one or more endothermic peaks Pa having an apex temperature appear in a temperature region below the resin melting point, and one or more endothermic peaks having an apex temperature in the temperature region exceeding the resin melting point and 130 ° C. or higher. Polypropylene-based resin expanded particles having Pb appearing and having a total heat quantity of endothermic peak Pb of 2 to 12 J / g, and molding the expanded particles That relates to the foamed bead molded article. |
