were analyzed. Results indicate that minimum torque, maximum torque, tensile strength, modulus, tear strength, hardness, and crosslink density volume fraction increased while elongation at break, swelling ratio and shear modulus decreased with the increasing silica loading in MS/NR/Silica hybrid composites. The aging test of corresponding hybrid composites was also evaluated at two different aging temperatures. The results in this work recommend that MS from marble processing industrial waste could be used as filler for cost savings in NR compounds.
