✦ Synopsis

The possibility of replacement of active fillers, e.g. carbon black, for cheap products, e.g. mica, were investigated. The physical-mechanical properties of SBR composites with mica and carbon black, using a constant total filler content (50 phr) have been studied. Tensile strength shows the best results when l0 phr of mica are used in combination with 40 phr of carbon black. These results are better than those for formulations in which carbon black is used alone. Relationships between mechanical behaviour and structure have been examined under scanning electron microscopy (SEM) on the fracture surface of the compositions.

The effects of silane coupling agents on styrene-butadiene rubber (SBR)-mica composites have been studied with special reference to the technical properties and polymer-filler interaction. Silane-treated mica improves polymer-filler interaction, which subsequently enhances the tensile and other tech

Since silica has strong filler-filler interactions and adsorbs polar materials, a silica-filled rubber compound has a poor dispersion of the filler and poor cure characteristics. Improvement of the properties of silica-filled styrene-butadiene rubber (SBR) compounds was studied using acrylonitrile-b
