Effect of solvent plasticization on polypropylene microcellular foaming process and foam characteristics

In this research, the effect of crystalline fraction of polypropylene (PP) on cell nucleation behavior was overcome by an introduction of solvent-plasticized step to the microcellular foaming in a solid-state batch-foaming process. Utilizing the plasticization performance of the solvent facilitated...
