THERMOPLASTIC RESIN PELLET, PROCESS FOR PREPARING THERMOPLASTIC RESIN PELLETS AND EXPANDED THERMOPLASTIC RESIN BEAD

摘要

A process for preparing thermoplastic resin pellets, including extruding a melt of a thermoplastic resin into a gas phase through a die in the form of strands, immersing the strands in a bath containing water and a surfactant to cool the strands, taking the cooled strands out of the bath, and cutting the taken-out strands into pellets.
