Abstract

Thermoplastic foams were produced from two different polypropylene nanocomposites by extrusion with the help of a chemical blowing agent. The strain hardening ratio decreased with increasing strain rate for one of the nanocomposites. For the other nanocomposite melt, the strain hardening ratio was unchanged with strain rate. Smaller cell sizes (less than 40 microns in diameter) were obtained when the nanocomposite melt displayed strain hardening levels in extensional flow that were maintained over a range of strain rates.
