There is a growing interest in the research community of the possibility of reducing or total
elimination of zinc oxide (ZnO) as activator in rubber compounds. This study therefore is an
attempt in that direction to study the effect of polyethylene glycol (PEG) as an alternative
activator in rubber compounds. Various levels of polyethylene glycol (0,2,3,4,5,6 phr) and zinc
oxide (as reference) were compounded with 100phr of natural rubber and other compounding
additives. The effects of both polyethylene glycol and zinc oxide were investigated on the
mechanical properties of the composite. The results obtained shows that polyethylene glycol has
the potential as an activator. But one significant phenomenon noticed in this study is that for
modulus polyethylene glycol shows no effect of reversion cure unlike zinc oxide. It is our hope
from evidence shown in this study that polyethylene glycol could provide alternative route for
activation of natural rubber compounds.
