Performance Resins In Tire Compounding

T. Carvagno, A. van Bennekom, S. Basu, G. van Ruler

When it comes to performance, not all resins are equal. With increasing global tire regulations, tire companies are developing new solutions to enhance tire tread performance. Although resins have been used for decades in tire formulations for tack and processing, there are many more resin options that demonstrate improvements in the performance triangle. When selecting a resin, key formulation parameters need to be taken into account to achieve optimal performance and processing results. Various classes of hydrocarbon resins show different performance tradeoffs based on the degree of compatibility between the resins and the rubber system. Therefore, when selecting the best resin for your performance targets, not all resins are equal.
