Effect of EPDM and high density polyethylene (HDPE) on mechanical andphysical properties polypropylene filled with ۲۰% talc

In this research, the impact of elastomer (EPDM) and high-density polyethylene (HDPE) onpolypropylene filled by ۲۰wt% mineral filler were investigated. The results correlated well withprevious research, and also revealing a relationship between melt flow index (MFI) and elastomercontent, particularly in the presence of HDPE. This research study shows toughness increases in thepresence of EPDM and by incorporating HDPE into the compound can be reached to highertoughness due to core-shell morphology. We provide a trend of mechanical properties that can guidecompounders to balance toghness and strength in their compounds. This research shows the oppositetrends of toughness and tensile strength in such a way that by incorporating POE and HDPE theimpact strength increases and tensile properties decrease
