Polyethylene materials are the
most widely used polymers which we encountered everywhere in our daily life. Some
of the advantages of the polyethylenes are the diversity of production types,
corrosion resistance, electrical insulation and recyclability. The main
production methods are compression molding, transfer molding, rotational
molding, injection molding, gas-assisted injection molding, extrusion and blown
film extrusion techniques. It is possible to increase the mechanical properties
of low density polyethylene materials by addition of high density polyethylene
materials. Both polymer has same monomers but their chemical structure and
bonding properties are different. Their physical properties can change with
their chemical structure and bonding properties. In this study, 25%, 50% and
75% by weight of high density polyethylene were added to low density
polyethylene. Granules were pre-mixed with a mechanical mixer before production
of the samples. Plastic injection molding machine was used for specimen
preparation. Density, hardness, tensile test, three-point bend test, compression
test, tear test and Izod impact tests were performed. Densities and hardness
values of the polymer blends decrease by the increasing amount of low density
polyethylene. In general, it was observed that the mechanical properties of the
polymer blends increase as the high density polyethylene content increase.
