PELLET-TYPE FOAMS OF NON-CROSSLINKED POLYPROPYLENE RESIN HAVING LOWER MELTING POINT AND PROCESS AND DEVICE FOR PRODUCING THE SAME AND MOLDED FOAMS THEREFROM “
Application 1844/DELNP/2003 published 2006-01-13, filed 2003-11-07
The present invention relates to a pellet-type non-crosslinked polypropylene foam having a melting point of 125 to 1400C, and a process and device for producing said foam. . Since the pellet-type foams of non-crosslinked polypropylene of the present invention has a lower melting point and a closed 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-type non-crosslinked polypropylene foams.
