This article reports on a systematic study that was conducted to investigate the effects of die geometry (i.e., pressure and pressure. drop rate) on the cell nucleation and growth behaviors of noncrosslinked highmelt-strength (HMS) polypropylene (PP) foams blown with supercritical CO2. The experimen...
