Improvement The Mechanical Properties of Styrene Butadiene Rubber By Using Silica Fume

Abstract

Styrene butadiene rubber (SBR) is considered to be one of the greatest important polymeric materials used as a bond, so we discussed in this study to improve its properties .This study covers the effect of silica fume on mechanical properties of styrene butadiene rubber reinforced with silica fume. The composites were prepared with (1 to 3 wt. %) of silica fume particles .The results had indicated  that the tensile strength and flexural strength are improved by (11.6% and 13.5%) respectively at 2 wt% and the hardness is  improved by (9.3%) at 3wt%.
