"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 1860/DELNP/2005 published 2007-01-19, filed 2005-05-04
The present invention relates to pellet-type non-crosslinked polypropylene foam having a melting point of 125 to 140°C, 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.
