METHOD OF MAKING FOAMED POLYMER BEAD

摘要

PROBLEM TO BE SOLVED: To provide a continuous method of making foamed polymer beads, capable of effectively increasing production efficiency and production amount. SOLUTION: The method of making foamed polymer beads mainly comprises a step for mixing a polymer with a high-pressure gas or a supercritical fluid in an extruder to create a homogeneous single-phase mixture and extruding the homogeneous single-phase mixture through a die to granulate foamed polymer beads each containing micro voids inside.
