Cassava peel is one of agricultural waste that abundantly found in environment. One approach to manage this waste is to apply it as filler in natural rubber latex. In this work, the cassava peel waste (CPW) was powdered and dispersed in alkanolamide-water dispersion system to modify its surface. The amount of fillers used was 0, 5, 10, 15, 20 and 25 phr (part per hundred rubber) and loaded in natural rubber latex (NRL) formulation system. The products then were formed by dipping method after the NRL formulation was pre-vulcanized at 70°C. The observed parameter includes crosslink density, tensile strength, tensile modulus and elongation at break. Scanning Electron Microscope (SEM) was used to study the morphology of tensile fracture in NRL film. The results show that 10 phr loading of modified fillers increases the crosslink density, tensile strength, and tensile modulus but decreases the elongation at break. SEM study also reveals that higher filler loading above 10 phr will create the agglomeration in rubber matrix.

Crosslinked natural rubber (NR)/microcrystalline cellulose (MCC) composite was prepared by dry mixing of NR with MCC extracted from cotton fiber. MCC was first extracted from cotton fiber by acid hydrolysis processing, then applied to block natural rubber as a reinforcement. MCC grafted maleic anhydride (MA) was also synthesized and applied to the composites to improve the compatibility between natural rubber and cellulose. Obtained cellulose samples were subjected to infrared spectroscopy (FTIR) to confirm the purity of cellulose structure and the presence of MA grafted on MCC chains. X‐ray spectroscopy (XRD) and thermogravimetric analysis (TGA) were investigated as well to see if there was any important change after modification. NR containing microcrystalline cellulose was formulated with vulcanizing agents and microcrystalline cellulose grafted MA for characterization. Micro‐scale dispersion of microcrystalline cellulose was observed by scanning electron microscopy (SEM). MCC showed positive contributions to tensile strength and thermal properties of composites as well. Mechanical properties of vulcanized rubber containing microcrystalline cellulose grafted MA gave a slightly better value compared to the reference sample without adding of the compatible agent. The presence of reinforcements helped NR composites to reduce solvent uptake, however there was no change in tensile strength after aging test.

Bentonite-filled ethylene propylene diene monomer (EPDM/Bt) composites were prepared using two roll mill compounding method and the effect of Bt loading on the thermal aging, swelling resistance and crosslink density of EPDM/Bt composites were studied. The effect of in situ addition of different silane coupling agents (SCAs) on the above properties at optimum Bt loading of EPDM/Bt composite was also investigated. Thermal aging test results show that the tensile strength and tensile modulus at 100% elongation (M100) increase initially for 2 days aged composites and decrease slightly after 4 days of aging, meanwhile the elongation at break (E b ) decrease gradually with aging period as compared to the unaged composites. Upon aging, swelling resistance increase initially indicating increased crosslink density of EPDM/Bt composite due to post-curing and reduced after 4 days of aging due to crosslink destruction and EPDM chain scissioning.
