AB - In this study, four different compounds were produced by adding different  proportions of mica powder (0-5-10-20%) to styrene-butadiene rubber. After  vulcanization, the crosslink density, hardness, density, tensile strength,  elongation percentage, and tearing strength of the compounds were measured.  In addition, the effects of crosslink density on mechanical properties were  discussed. The physio-mechanical properties of the new compounds produced  were compared both among them­selves and with the properties of the rubber  being referenced. It was observed that increasing the crosslink density of  mica powder provided an advantage in terms of hardness, tensile strength,  tearing strength, and percentage elongation properties. To explain the  changes in mechanical properties, the tensile fracture surfaces were  determined by SEM and energy dispersive spectroscopy. In the light of the  obtained results, it was determined that the use of carbon black could be  reduced by using mica powder in the rubber industry.
