Effect of impact modifier to the performance of polyamide 6/high density polyethylene nanocomposite / Farizah Hamid

Blending of polyamide 6/high density polyethylene (PA6/HDPE=70/30 wt%) was prepared by melt compounding using a twin screw extruder followed by injection moulding. For optimum formulation, PA6/HDPE blends were blended with 1 to 5 phr of ethylene vinyl acetate (EVA) with incorporation of 3-7 wt% orga...

For optimum formulation, PA6/HDPE blends were blended with 1 to 5 phr of ethylene vinyl acetate (EVA) with incorporation of 3-7 wt% organoclay (MMT) and in the presence of HDPE-g-MAH (2-8 wt%) as compatibilizer.
