Application of sustainably sourced silane-terminated resins in EV tread development

Silane-terminated diene resins have been shown to be useful additives for improving the performance balance of traction and rolling resistance in tire tread compound development. The synergistic mechanism of polycondensation and interpenetrating network formation involving the silica filler, silane coupling agents and silane-terminated diene resins has been established. EV tire development will require a new balance of properties highlighting abrasion resistance and durability without sacrificing traction. In the present study, the extension of the technology to higher filler-loaded EV compounds is explored, focusing on minimizing filler-filler interactions. Sustainably sourced functionalized resin options are included in the technology presented.
