The compatibilizer effect of ENR-50 on the tensile properties and morphology of linear low density polyethylene (LLDPE)/ recycled acrylonitrile butadiene rubber (NBRr)/ rice husk powder (RHP) composites has been studied. The RHP size utilize in this work is 150 – 300 μm. LLDPE/NBRr/RHP composites were prepared by melt mixing technique at 180 °C for 9 minutes at 50 rpm rotor speed using heated two roll mill. The series of composites investigated were 100/0/5, 80/20/5, 70/30/5, 60/40/5, 50/50/5, and 40/60/5. The composites were analysed by using tensile test and morphology examination. The result showed that the tensile strength of composite was decreased with the increasing of recycled acrylonitrile butadiene rubber (NBRr) content while elongation at break (Eb) were increased. However, the tensile strength and elongation at break result for composites with ENR-50 as compatibilizer showed higher values. The morphological finding supports the tensile properties which indicate better interaction between the RHP filler and LLDPE/NBRr matrix in the presence of ENR-50 compatibilizer.

The thermal degradation of linear low density polyethylene (LLDPE)/ recycled acrylonitrile butadiene rubber (NBRr)/ rice husk powder (RHP) composites with and without epoxidized nature rubber (ENR-50) were studied. The thermal degradation of this composite was evaluated for 30 days using oven ageing. The NBRr content was manipulated in this work and the particle size for the rice husk powder was 150-300 μm. The composites were prepared by using two-roll mills at 180 °C and then were compressed at 180 °C to produce a 1 mm thin sheets. The dumbbell samples then were analysed by using universal testing machine and field emission screening electron microscopy for tensile and morphological properties. The results obtained showed that tensile strength was decreased with the increasing of NBRr content for both oven ageing and control composites. However the oven ageing composites recorded much lower tensile properties. This may possibly due to the chain session of LDPPE matrix at longer heat exposure duration. This finding is supported by the morphological micrograph with less ductile features of the respective specimens.
