Abstract :
Now a days, rubbers and plastics are widely
used in wide variety of t applications and this is why the
recent decades are sometimes called the “Plastic Age”.
However, their waste are non-biodegradable and remain
long period of time in environment cause hazardous
negative impacts. Polymer recycling is the only remedial
measure currently available to reduce the environmental
impacts. Thermoplastic Elastomers are novel
constructional polymers, which are physically cross
linked materials made up of a Thermoplastic and
Elastomer. In present study, Recyclable Polyethylene
was blended with Natural Rubber in different
proportions using two roll mill and semi-automatic
compression moulding machine at 185°C. The main aim
of this study was to investigate the effect of blend ratio
on physical, thermal, mechanical, rheological properties
of PE/NR blends. The result showed that, when rubber
content in the blend increases, the tensile strength and
modulus decreases. But they shows excellent elongation,
flexural strength and impact resistance, which is widely
used in many fields like automotive, construction,
electrical appliances etc. The study also proved that the
blend with high Natural Rubber content had low Melt
Flow Index and Vicat Softening Temperature than the
blend with low Natural Rubber. The obtained results
recommend that PE/NR blend can be used for
environmental remediation from postconsumer PE
wastes and to realize new goods with high performance
for various applications
