Managing polymer filler interactions for better tire processing and properties

Using new additve chemistry it is possible to control polymer filler interactions leading to more efficient mixing and superior down-line processing characteristics. The ability to influence both internal and external interactions allows for better management of the behavior of compound interfaces and as a result both tack and tear properties are more easily controlled. Vulcanization efficiency leading to better compound stiffness and management of hysteresis are also evident. Several examples based on advanced silica and carbon black-filled systems suited to different tire components are featured. The contibution toward both processing and tire energy efficiencies are highlighted.
