This study investigated the effect of PVC formulation on the cell morphology of rigid PVC foamed with supercritical CO2 in a continuous extrusion process. Cell morphology was controlled by blending two acrylic based processing aids (allacrylic foam modifier K-400 and acrylic-based impact modifier KM-334) using a mixture design. The experimental results indicated that fusion is not the …
