Studing The Mechanical Properties Of Ternary Blends Of Hdpe/Pp/Abs

Abstract

In this work a type of polymer blend has been prepared from mixing differentpercent (40,50,60, and 70) % of High-density polyethylene, polypropylene and adding 6%weight percent of acrylonitril-butadiene-styrene by using single-screw extruder. Theextrusion process concentrated on the homogeneous mixing manner among materialsthrough a regular selection of machine screw revolution per minute and temperature used inextrusion process. Some of mechanical properties such as impact strength, modulus ofelasticity and shore hardness of polymer blend, were determined at different weight fractionof blend. It was found that the addition (6%wt) of ABS to the binary blends HDPE/PP leadsto increase the modulus of elasticity, the impact strength and shore hardness.On the other hand increasing % HDPE content from 40 to 70wt% in HDPE/PPternary blends leads to increase the modulus of elasticity from 166.35 Mpa to 186.25 Mpa,and impact strength increase from o.o52 to o.o6 J/mm2 while decreases the shore hardnessfrom 89 to 69.
