Virgin NBR and recycled NBR particles, which were pulverized from NBR scraps by high temperature shear-crushing technique, were blended with different mixing ratio. The effects of the recycled NBR content on the cure characteristics and physical properties of these blends were investigated and resistance properties of these blends to heat and various fluids were also studied. The study of cure characteristics showed that the viscosity increased but the scorch time decreased. The physical properties of rubber blends were improved with the addition of the recycled NBR for heat resistance and various fluid tests.
