The compatibilizer effect of ENR-50 on the tensile properties of high density polyethylene (HDPE)/recycled acrylonitrile butadiene rubber (NBRr)/banana skin powder (BSP)/ composites has been studies. HDPE/NBRr/BSP composites were prepared by melt mixing technique using twin-screw at 180 °C for 9 minutes at rotor speed 50 rpm. The six different composites studied were 100/0/5, 80/20/5, 70/30/5, 60/40/5, 50/50/5, and 40/60/5. As for compatibilized composite a fix 5 wt% of ENR-50 was evaluated. The specimens were analysed for tensile strength and elongation at break (Eb). The results showed that tensile strength and the elongation at break were decreases with the increasing of NBRr loading. However for ENR-50 compatibilized composites, higher tensile strength and elongation at break was recorded. The ENR-50 was found to be an excellent compatibilizer for HDPE/NBRr/BSP composites.

The thermal degradation of high density polyethylene (HDPE)/ recycled acrylonitrile butadiene rubber (NBRr)/ banana skin powder (BSP) composites with and without ENR-50 are fabricated and studied. The thermal degradation of this composite was evaluated for 30 days oven ageing. The BSP with size of 150 – 300 μm was utilized in this work. All compounds were mixed using heated two roll mill at 180 °C. The compounds were molded in a hot press machine at 180 °C for 11 minutes to produce 1 mm thin sheet. Then the sheet were cut into dumbbell shape for the mechanical testing using universal testing machine. The tensile strength of high density polyethylene/ recycled acrylonitrile butadiene rubber/ banana skin powder composites showed the decreasing trend with the increasing NBRr loading for the composites with and without ENR-50. However, the result for the oven ageing showed lower tensile strength. This may due to the chain session of PP matrix at heat exposure duration of 30 days.
