Abstract
Cassava peel waste is one of the renewable biomass resources which has the potential to be derived into microcrystalline cellulose. Microcrystalline cellulose was produced from cassava peel waste by using delignification process, followed by bleaching process and controlled acid hydrolysis. The structural properties of microcrystalline cellulose obtained were examined by X-Ray Diffraction (XRD). The filler loading was 0-25 pphr microcrystalline cellulose and 1% wt alkanolamide. In this research, alkanolamide was used as compatibilizer agent for natural rubber latex products. The filler dispersion was poured into latex system and followed by pre-vulcanization at 70°C. The natural rubber latex films were produced by coagulant dipping method and dried at temperature 120°C for 20 minutes. It was found that the incorporation of microcrystalline cellulose derived from cassava peel waste as fillers at 10 pphr filler loading in natural rubber latex has improved the crosslink density and mechanical properties of the natural rubber latex products such as tensile strength, tensile modulus, but decrease elongation at break.
