Pre-expanded particles of polypropylene resin and inmolded foamed article using the same

摘要

The present invention aims at preparing polypropylene resin pre-expanded particles capable of providing an inmolded expanded article which prevents pollution of a mold by polypropylene powder at molding, packed products from being damaged by friction due to vibration at transport, and powder generation at the same time. Polypropylene resin pre-expanded particles comprising a resin composition containing a fatty acid amide compound is used.
