A RUBBER COMPOSITION FOR TIRE WITH IMPROVED CUTTING AND CHIPPING RESISTANCE

摘要

PURPOSE: A rubber composition for tires obtained by incorporating a ruthenium complex into conventional rubber compositions is provided, which improves chip cut resistance while maintaining heat build-up property. CONSTITUTION: In a tire rubber composition for off road, 5 to 10phr of a ruthenium complex is added to conventional rubber compositions to improve chip cut resistance. The composition improves chip cut resistant performance without lowering of heat build-up characteristics and abrasion resistant characteristics.
