Title:
ポリプロピレン系樹脂発泡粒子、ポリプロピレン系樹脂型内発泡成形体、およびポリプロピレン系樹脂発泡粒子の製造方法
Document Type and Number:
Japanese Patent JP7152480
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing polypropylene resin foam particles which enable the achievement of low heating properties and short cycle properties at the same time with respect to a polypropylene resin in-mold foam molded body having good surface properties, fusibility and compressive strength. Provided is polypropylene resin foam particles which have specific 1-butene amount, MFR and melting point, while having specific two peak temperatures and high-temperature heat quantity ratio as determined by differential scanning calorimetry.
