Retreaded truck tire test – breakthrough for NR Silica/Silane systems

Evonik gained a lot of experience in compounding natural rubber and Silica/Silane systems in the past. An experimental field test was performed to investigate the performance of the pure Silica/Silane technology versus N234 reinforced NR based truck tire treads on the drive-axles. The benefits in wet and rolling resistance performance with Silica/Silane systems were achieved, without deteriorating the abrasion resistance, which is on the same level as the carbon black reference – a breakthrough.
