Abstract: Comparison of mechanical properties of natural rubber vulcanizates filled with hybrid fillers (carbon black/palm kernel shell and palm kernel shell/sandbox seed shell). The compounding was done at varying ratios 0/60, 10/50, 20/40, 30/30, 40/20, 50/10, 60/0phr for the hybrid carbon black/palm kernel shell (CB/PKS) and palm kernel shell/sandbox seed shell (PKS/SSS), using two roll mill. The results showed that incorporation of hybrid CB/PKS and PKS/SSS fillers into the natural rubber vulcanizates generally increased the tensile strength, modulus and hardness at hybrid filler loadings 0/60, 20/40, 30/30, 40/20, 50/10 and 60/0phr of the composites produced, whereas the elongation at break, abrasion resistance and compression set decreased. The hybrid CB/PKS filled natural rubber vulcanizates exhibited higher tensile strength, modulus and hardness than those of the hybrid PKS/SSS filled natural rubber vulcanizates but lower elongation at break, abrasion resistance and compression set than the hybrid PKS/SSS filled natural rubber vulcanizates.
