Vincent Greff

Vincent started his professional career by joining Cray Valley in 2021 as part of the R&D Laboratory Team, and worked on rubber compounding and liquid resin modification. After one and a half years in this position, he had the opportunity to be promoted as the Rubber Technical Manager for Cray Valley to support customers on technical matters of their products portfolio.


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.
