Walnut Shells’ Potential Use as Biofillers in Natural Rubber Composites
Abstract: The study assessed the potential of walnut shells as a filler in natural rubber composites. Walnut shells were finely ground, sieved through a 75 μm mesh, and incorporated into natural rubber at different filler loadings: unfilled, 20 parts per hundred rubber (phr), 30 phr, 40 phr, and 50 phr. The physicochemical properties of the walnut shell powder were analyzed, yielding results of 5.30 for pH, 10.10% for moisture content, 2.50% …
