Effect of Different Carbon Black Varieties on Performance of Support Compounds for Run Flat Tire
Using three different kinds of carbon black to match NR/BR with different ratios separately,a support compound formula was designed with a focus on mechanical strength,flexural resistance and heat build-up performance,and the effect of the support compound on the zero-air pressure durability of run flat tire was studied.The results showed that the zero-air pressure durability of finished tires had a strong correlation with the hardness and rigidity of the support compound.The flexural resistance and heat build-up performance of the support compound with different hardness did not show a significant improvement effect on the zero-air pressure durability of the finished tire.
