Investigation of the effect of silica particles and silane coupling agent on silica-filled tire tread compounds

Enhancing attributes such as abrasion resistance, wet grip, and rolling resistance significantly impacts the overall performance optimization in tire tread applications. These attributes are predominantly influenced by the dispersity of silica filler within tire tread compounds. Therefore, it becomes imperative to enhance silica dispersion by thoroughly investigating the impact of each constituent in the tire tread compound. This study aims to elucidate the effects of silica particle size and silane coupling agents on tire tread compound properties. The results demonstrate that larger specific surface area silica particles alongside 3-mercaptopropyltrimethoxysilane coupling agents effectively reduce filler-filler interactions and enhance silica dispersion within the tire tread compound. Consequently, these improvements contribute to the overall enhancement of tire tread compound performance. These findings offer valuable insights into advancing the reinforced performance of tire tread compounds through the synergistic utilization of each constituent.
