The purpose of this research is to investigate the effect of sago starch loading on the mechanical and biodegradation properties of Natural Rubber Latex (NRL) composites.The used of Sago starch is an attractive alternative in developing cheap degradable materials which are environmental friendly, biodegradable and once degrade, it is compostable.The sago starch loading for each composite was varied from 5 to 25 phr.Two methods of sago starch additions have been employed in this research.
