Abstract

　ポリプロピレン系樹脂発泡粒子の特徴である圧縮物性、耐熱性などの優れた性質を損なうことなく、低い加熱温度での型内成形にて同等の性質を有するポリプロピレン系樹脂発泡粒子成形体を得ることができる優れたポリプロピレン系樹脂発泡粒子を提供することを目的とする。 　本発明は、樹脂融点が１１５～１３５°C、且つオルゼン曲げ弾性率が５００ＭＰａ以上のポリプロピレン系樹脂からなるポリプロピレン系樹脂発泡粒子であって、該発泡粒子の表面のアッシュの量が３０００重量ｐｐｍ以下（０も含む）であり、該発泡粒子は、ポリプロピレン系樹脂発泡粒子１～３ｍｇを示差走査熱量測定装置によって１０°C／分の昇温速度で、常温から２００°Cまで昇温したときに得られる第１回目のＤＳＣ曲線において、樹脂融点以下の温度領域に頂点温度を有する１以上の吸熱ピークＰａが現れると共に、樹脂融点を超え、且つ１３０°C以上の温度領域に頂点温度を有する１以上の吸熱ピークＰｂが現れ、吸熱ピークＰｂの総熱量が２～１２Ｊ／ｇであるポリプロピレン系樹脂発泡粒子、および該発泡粒子を成形してなる発泡粒子成形体に関する。
