Abstract

A particulate polymeric composition capable of being processed to provide expanded articles having a density lower than or equal to 50 g/l and a closed cell content of at least 60% as specified by ASTM D-2856, wherein resulting particulates have a shape factor ranging from 0.6 to 0.99; and wherein the particulate polymeric composition is produced according to a process that prepares expandable granules based on thermoplastic polymers, through a granulation die.
