Application of Cobalt-based BR in Tire Sidewall Compound

MA Wei-de

Abstract

The application of carbon black or carbon black/silica filled cobalt based BR0150/NR and carbon black filled nickel based BR9000/NR in tire sidewall compound was investigated.The results showed that,compared with the carbon black filled BR9000/NR,the Mooney viscosity of carbon black filled BR0150 compound was lower,the flowability was better,the optimum curing time and scorch time were similar,and the properties of vulcanizates were also similar;the Mooney viscosity of carbon black/silica filled BR0150/NR compound was higher,the optimum curing time was longer,the physical property and aging property of vulcanizates were similar,but the tear strength increased significantly,and anti-cutting performance and flexing resistance were improved.
