Influence of process variables on chemical devulcanization of sulfur-cured natural rubber
The present study investigated the effects of two types of natural rubber and different blend ratios on the cure, tensile properties
and morphology of natural rubber/recycled chloroprene rubber blends. The blends of natural rubber/recycled chloroprene rubber
were prepared by using laboratory two-roll mill. The result showed that the cure time prolonged with the addition of recycled
chloroprene rubber (rCR). Comparability, natural rubber/recycled chloroprene rubber (SMR L/rCR) blendcured rapidly than
epoxidized natural rubber/recycled chloroprene rubber (ENR 50/rCR) blend. The addition of rCRalso caused a decrement in the
tensile strength and elongation at break for both rubber blends. The SMR L/rCR blendsshowed higher tensile strength and
elongation at break compared to those of ENR 50/rCR blends at any blend ratios.
