    • A polypropylene resin foamed bead from which a foamed bead molded article excelling in appearance, heat resistance and mechanical properties can be obtained at the molding temperature lower than that for conventional polypropylene resin foamed beads; and a foamed bead molded article obtained by molding the same. The polypropylene resin foamed bead is characterized by having such a crystal structure that in the first DSC curve obtained when the temperature of the foamed bead sample is raised from ordinary temperature to 200° C. at a temperature rising rate of 2° C/min by a differential scanning calorimetry, there appear a main endothermic peak of 100° to 140° C. endothermic peak apex temperature exhibiting 70 to 95% endothermic peak calorific value based on the total endothermic peak calorific value and two or more endothermic peaks exhibited on the high temperature side with respect to the main endothermic peak.
    • 在比常规聚丙烯树脂发泡颗粒低的成型温度下,可以获得在外观,耐热性和机械性能上优异的发泡粒子成型体的聚丙烯树脂发泡珠粒; 和通过将其模塑而得到的发泡粒子成型品。 聚丙烯树脂发泡珠粒的特征在于具有这样的晶体结构,即当以2℃/ min的升温速度将发泡珠粒样品的温度从常温升高到200℃时获得的第一DSC曲线中, 差示扫描量热法,基于总吸热峰发热值和在高温下显示的两个或更多个吸热峰,出现100℃至140℃的吸热峰顶峰的主吸热峰,显示70至95%的吸热峰发热量 温度方面相对于主吸热峰。
