The incorporation of both fillers increases the scorch time, t 2, and cure time, t 90, of SMR L vulcanizates. At a similar filler loading, feldspar exhibited longer t 2 and t 90 but lower values of maximum torque, MHR, and torque difference, MHR–ML than did silica-filled SMR L vulcanizates. For mechanical properties, both fillers were found to be effective in enhancing the tensile strength (up to 10 phr), tensile modulus, and hardness of the vulcanizates. However, feldspar-filled SMR L vulcanizates showed lower values of mechanical properties than did silica-filled SMR L vulcanizates. Swelling measurement indicates that swelling percentages of both fillers-filled SMR L vulcanizates decrease with increasing filler loading whereas silica shows a lower swelling percentage than feldspar-filled SMR L vulcanizates. Scanning electron microscopy (SEM) on fracture surface of tensile samples showed poor filler–matrix adhesion for both fillers with increasing filler loading in the vulcanizates. However, feldspar-filled SMR L vulcanizates showed poorer filler–matrix adhesion than did silica-filled SMR L vulcanizates. Thermogravimetric analysis (TGA) results indicate that the feldspar-filled SMR L vulcanizates have higher thermal stability than do silica-filled SMR L vulcanizates. 2014-06-06T09:10:56Z 2014-06-06T09:10:56Z 2005 Article Polymer-Plastics Technology and Engineering, vol.43, 2005, pages 1323-1344 0360-2559 http://www.tandfonline.com/doi/abs/10.1081/.U5F-8YaQZYY http://dspace.unimap.edu.my:80/dspace/handle/123456789/35156 10.1081/PPT-200030163 en Taylor Francis Inc
