Abstract:Silica-filled styrene−butadiene rubber (SBR) compounds are state-of-the-art materials to produce tire treads. This is based on their good dynamic mechanical properties, resulting in a high wet grip and low rolling resistance. The application of silica as a filler requires the addition of a silane coupling agent that facilitates the chemical coupling to the rubber molecules, reducing filler−filler interactions in favor of filler−rubber interactions. However, the current solutions are based on the formation of s… Show more
