Abstract

This study investigated the effects of various isothermal-crystallization- kinetics on the extrusion foaming behavior of PLA-nanosilica and PLA-talc samples while using supercritical CO₂ as the blowing agent. The results showed that various isothermal-crystallization-kinetics along the second extruder and die affected the PLA's foaming results differently. At the T _criticai isothermal temperature, the fast growing crystals suddenly dropped the die pressure and caused a nonuniform foam structure whereas at T < T_Critical, a larger number of nucleated crystals contributed to cell nucleation and the uniform foam morphology.
