摘要： Provided are polyvinylidene fluoride resin expanded beads which can be molded by in-mold molding and thus stably provide, without impairing excellent characteristics inherent in polyvinylidene fluoride resin, molded articles having excellent mechanical properties. Polyvinylidene fluoride resin expanded beads, characterized in that when 1 to 3 mg of the expanded beads are subjected to heat-flux type differential scanning calorimetry (DSC) wherein the beads are heated from 25°C to 200°C at a temperature rise rate of 10 °C/min, the obtained DSC curve (of first heating ) has both an inherent endothermic peak which is inherent in polyvinylidene fluoride resin and one or more higher-temperature endothermic peaks which appear on the higher-temperature side of the inherent endothermic peak, the quantity of heat of melting of the higher-temperature endothermic peaks being at least 0.5 J/g.

摘要： Disclosed are expanded polypropylene resin beads which enable the heat molding of expanded polypropylene resin beads at low steam pressure and can provide an expanded mold with sufficient rigidity and heat resistance. The multilayer expanded resin beads are formed by expanding multilayer resin beads comprising a core layer formed from a polypropylene resin and a coating layer formed from a different polypropylene resin to that which forms the core layer. The multilayer expanded resin beads can be molded in-mold at a steam pressure lower than the steam pressure for molding single-layer expanded beads which would result from expanding the single layer resin beads made from the polypropylene resin which forms the core layer. The coating layer to core layer resin weight ratio in the aforementioned multi-layer resin beads is not less than 0.001 and not greater than 0.040 and the expansion ratio of the expanded beads, the average value of the thickness of the coating layer of the expanded beads, calculated based on the coating weight ratio of the multi-layer resin beads, is not less than 0.1µm and not greater than 3.0µm.
摘要翻译：本发明公开了一种发泡聚丙烯树脂珠，其能够在低蒸汽压力下对发泡聚丙烯树脂珠进行热模塑，并可提供具有足够刚性和耐热性的膨胀模。多层发泡树脂珠是通过将由聚丙烯树脂形成的芯层和由不同的聚丙烯树脂形成的涂层与形成芯层的多层树脂珠扩展成多层树脂珠形成的。多层发泡树脂珠可以在低于蒸汽压力的蒸汽压力下模制成型，用于模塑单层发泡珠，这是由于形成芯层的聚丙烯树脂制成的单层树脂珠而膨胀的。上述多层树脂珠中的涂层与芯层树脂重量比不小于0.001且不大于0.040，发泡珠的膨胀比，发泡珠的涂层厚度的平均值，基于多层树脂珠的涂布重量比计算，不小于0.1μm且不大于3.0μm。
