Potential of electron beam irradiated hdpe/epr blend as shoes sole
This study focuses on the mechanical effect of different composition of polymer blend. Polymer blend of high density polyethylene (HDPE) and ethylene propylene rubber (EPR) were selected and varied by three different compositions which are 70:30, 50:50 and 30:70. HDPE-EPR blend is believed to...

Summary: | This study focuses on the mechanical effect of different composition of polymer
blend. Polymer blend of high density polyethylene (HDPE) and ethylene
propylene rubber (EPR) were selected and varied by three different compositions
which are 70:30, 50:50 and 30:70. HDPE-EPR blend is believed to be the best
material for sole shoe. In which, HDPE has good flexibility while, EPR can
maintain optimum performance at high and low temperature as well as provide
better gripping characteristic that suits for insole and outsole sport shoe. On the
other hand, the time efficiency of electron beam radiation on these polymer blends
helps in improving the croslinking of HDPE-EPR blend. The aim of this paper
was to find the optimum composition of electron beam irradiated polymer blends
for sole shoes especially in sports application. These irradiated polymer blends were produced by melt blending, underwent compression moulding and then were
irradiated by electron beam at 100 kGy/s. Mechanical test of tensile and hardness
test were investigated and the morphology of the failure fracture was analysed by
field emission scanning electron microscopy (FESEM). The polymer blend with
70% of HDPE and 30% of EPR showed the optimum result of tensile strength,
tensile modulus and hardness as well as ductile failure image. |
