Abstract
The mechanical properties and the morphology of the ternary blend of
LDPE/LLDPE/HDPE were studied.
In the present work LDPE was mixed with equal amount of LLDPE and different
wt% of HDPE (0, 10, 20 and 30 %) using the two roll mills. The mechanical properties
and the morphology were specified by measuring the (tensile, hardness, impact
properties) for the former, and photomicrograph for the later. From the tensile test
results it was found that the tensile strength at break of the ternary blend increased with
increasing the HDPE contain also the increases of wt% HDPE leads to decrease the
elongation at break. For the hardness test it was found that the shore hardness of the
ternary blends increased with the increasing the HDPE contain .On the other hand the
impact test carried out also and it was found that the addition of HDPE leads to
decrease the impact strength . Nevertheless, optical micrograph results that the HDPE
serves as a compatabilizing agent for immiscible LDPE/LLDPE
