Abstract

　ポリプロピレン系樹脂発泡粒子を金型内に充填し、水蒸気で加熱成形して得られる発泡成形体において、成形後の収縮・変形を回復させるための養生時間が短くても変形が少なく、対金型寸法収縮率が小さく寸法安定性がよく、かつ表面性の優れた発泡成形体を得ること。融点が１２５°C以上１６０°C以下のポリプロピレン系樹脂を発泡させて得られる、真倍率が２０倍以上３５倍以下のポリプロピレン系樹脂発泡粒子において、該ポリプロピレン系樹脂発泡粒子の１７０°Cでの溶融粘度が７５００ｐｏｉｓｅ以上、１２０００ｐｏｉｓｅ以下、溶融張力が０．５ｇ以上１．８ｇ以下であり、該ポリプロピレン系樹脂発泡粒子のセル径が２００μｍ以上１０００μｍ以下であることを特徴とするポリプロピレン系樹脂発泡粒子。
