Abstract
Substantially non-crosslinked polypropylene resin foamed particles having a bulk density of from 8 to 100 g/l and a particle diameter of from 1 to 5 mm, the polypropylene resin is composed of from 5 to 30% by weight of a room-temperature xylene soluble matter having an ethylene content of from 20 to 80% by weight and from 70 to 95% by weight of a room-temperature xylene insoluble matter having a main melting peak temperature of from 130.degree. to 158.degree. C. The foamed particles provide a foamed product having well-balanced properties, such as low-temperature moldability, heat resistance, recovery from compression, and the like.
