The interest in the utilization of bio fillers in thermoplastics has increased recently, mainly due to the need in
overcoming the environmental problems caused by the agricultural by products. Based on former exploratory
research, we used seaweed fiber as a novel bio filler for the production of polypropylene (PP) biocomposites.
Maleic anhydride grafted PP was applied as compatibilizers. The incorporation of the bio fillers at compositions
ranging from 10-30% was carried out by melt compounding in extruder and then injection moulded into
standard test samples. Mechanical and physical characteristics of the composite systems were studied to
evaluate the effect of seaweeds content on PP. It has been found that while there is a decrease in elasticity
modulus, tensile strength at break and elongation etc., the hardness and melt flow index were found to be
increased with the seaweed content.
