Effects of Nanoclay and CO₂Content on Foaming Behaviors of PP/PS Alloys

Abstract:

Microcellular foaming behavior of polypropylene/polystyrene (PP/PS) composites with or without the addition of nanoclay was compared in an extrusion foaming process by using supercritical CO₂ as the foaming agent. The influence of CO₂content on foaming of the composites was investigated in the study. Our experiment results demonstrated that the introduction of nanoclay dramatically improved the foaming of the PP/PS blends with increased cell-population density and decreased cell size. With the increase of CO₂injected in the foaming process, cell-population density of the foam samples further increased.
