The object of this paper is to study the effect of different levels of halloysite nanotubes (HNTs) loading on tensile strength and impact strength of PP/NBR/HNT nanocomposite in presence of PP-g-MA as compatibilizer. Samples containing 20 wt% of NBR, 1, 3 and 5 wt% of HNTs and 10 wt% of PP-g-MA were produced using counter rotating twin-screw extruder. HNTs enhanced both of the mechanical properties. At all levels of loading, tensile strength plot showed an ascending trend, however in case of impact strength, the optimum level of HNTs was achieved at 3 wt%. Scanning electron microscopy was utilized to figure out the effect of HNTs loading on the way the elastomer phase dispersed into the continuous phase or the matrix.
