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