This research presents the foaming behaviors of linear polypropylene (PP) and PP/clay nanocomposites blown with supercritical CO 2 . The cell nucleation and expansion behaviors of the linear PP and PP‐based nanocomposites at various clay contents during extrusion foaming are studied. The experimental results indicate that the nano‐particles have a positive impact on improving the cell morphology, the cell density and the expansion ratio of the linear PP foams. © 2010 Wiley Periodicals, Inc.
