Abstract

The object of this paper was to investigate extrusion foaming of different nanocomposites prepared with a linear polypropylene and chemically modified montmorillonite. Various polypropylene nanocomposites prepared had different rheological properties in extensional flow and different thermal characteristics. A chemical blowing agent was used for foaming of these nanocomposites in a single screw extruder. Extruded foam quality was evaluated in terms of mean cell size and cell size distribution with SEM. In addition to providing a greater concentration of nucleating sites for foaming the polymer matrix, addition of nanoclays with appropriate compatibilizer has the potential for improving melt strength and altering the crystallization kinetics. All these effects are important for producing closed cell foams with a more uniform cell size distribution.
