Abstract

In this work, the dependency of linear polypropylene (LPP) (MFI of 18 g/10min) foaming behavior on nanoclay addition and various processing parameters were explored. Because of the low cost of LPP, there is a high industrial interest in this approach. In our work, two processing methods in a twin screw extruder were utilized to see the influence of nanoclays dispersion within the polymer. A single screw extruder was used for foaming in a range of temperatures and Supercritical CO2 was used as the blowing agent. X-Ray diffraction, SEM, and density measurements were utilized to explore the nanoclays' exfoliation, cell density, and expansion ratio, respectively.
