Zusammenfassung:	The present invention relates to a pellet-type non-crosslinked polypropylene foam having a melting point of 125 to 140.ordm.C, and a process and device f or producing said foam. Since the pellet-type foams of non-crosslinked polypropylene of the present invention has a lower melting point and a close d cell content of 80% or more, it is advantageous to mold such foams. The present invention also relates to an article molded from the above pellet-ty pe non-crosslinked polypropylene.foams.
