Abstract: Blends of nitrile rubber and reclaimed rubber containing different levels of a coupling agent, Si 69 (bis(3- triethoxysilyl propyl)(tetrasulphide) were prepared and the cure characteristic's and mechanical properties were studied. Optimum loading of Si-69 was found to be a function of blend ratio. 3 phi- of Si 69 in a 70:30. Blend was found to be the optimum combination with respect to the mechanical properties. The rate and state of cure were also affected bv the conp/ing agent. Tensile strength, tear strength and abrasion resistance were improved in the presence of coupling agent. While the state of cure improved, the cure rate and scorch time decreased with increasing silane content. Ageing studies showed that the blends containing the coupling agent were inferior to the unmodified blends.
