A simple melt blending method for preparing PP/HMSPP foaming composites with superior surface appearance and mechanical performance

Increasing mold temperature is effective to improve the surface quality of injection molding foamed products, but high mold temperature often leads to deteriorative cellular quality. Based on this, the polypropylene/high melt strength polypropylene (PP/HMSPP) composites with temperature insensitivit...
