Brazilian muscovite mica was used as filler in vulcanized compositions of styrenebutadiene rubber (SBR) in partial replacement of silica. Physico-mechanical properties of the compositions, such as tensile and tear strength, 100% modulus, elongation at break, hardness, abrasion loss and resilience have been studied. The investigations have shown that it is possible to partially replace silica for mica, without remarkable changes in some properties. Relationships between mechanical behaviour and structure have been examined under scanning electron microscopy (SEM) on the fracture surface of the compositions.
