Improvement of Locally Produced Low- Density Polyethylene


In the present work, a polymer composite was fabricated by mixing LDPEwith different wt% of pigment (Fe2O3 and TiO2) to obtain desirable properties infabrication single screw-extruder was utilized , this mixing machine operated at atemperature between (150-170)Co.some of mechanical properties, such as tensile,impact, hardness and bending test were determined at different weight fraction ofcomposite materials. It was found that the addition of pigment (TiO2 and Fe2O3) to theLDPE leads to increase the modulus of elasticity, tensile strength, tensile strength atbreak, shore hardness on other hand it decreases the % elongation at break, and for theimpact strength.
