Abrasion Improvement of SBR/BR based Tyre Tread Formulation Using High Dispersible Silica

Partly substitution of carbon black with high dispersible silica in a model tyre tread compound was studied. A box behnken design was employed to study of silica substitution in different oil and sulfur contents. The compounds were prepared in 2 liter banbury mixer and were finalized on a two roll mills. Regression models for five critical properties were successfully developed. Using regression models and with the aid of nonlinear programming approach, a formula with improved abrasion for tyre tread was developed
