Abstract
The novelty of microcellular injection molding technology opens a wide range of opportunities for the preparation of porous parts made from biobased and biodegradable polymers, such as poly(lactic acid), polyhydroxybutyrate-valerate, and their nanocomposites with enhanced and multifunctional properties. This chapter reviews the fundamental foaming mechanisms and manufacturing technology of microcellular injection molding. Then it describes the development of the microcellular injection molding process and strategies such as blends and composites foaming with biodegradable polymers, natural fibers, and inorganic fillers, as well as developing novel processing techniques, to obtain high-performance polymer foams with specific mechanical properties. Finally, it finishes with some comments on the future outlook of microcellular injection molding technology.
