Cobalt Butadiene Rubber

Our polybutadienes catalyzed by Cobalt have a high 1.4-cis content combined with high 1,2-vinyl content and a broad molecular weight distribution that allows for easy processing and the production of high quality rubber goods. Co-BRs can be blended with NR for goods having thick sections. Provided that the compounds are formulated and processed correctly, the Co-BR vulcanizates have good resistance to aging, reversion, abrasion and flex cracking, good low temperature flexibility and high resilience.

 

Key Properties  

Provided that the compounds are formulated and processed correctly, the vulcanizates have good resistance to aging, reversion, abrasion and flex cracking, good low temperature flexibility and high resilience.

Applications

CoBRs can be used in sidewall and tread compounds for tires. Further typical applications are conveyor belts, golf balls, footwear soles, etc. They can be blended with NR for goods having thick sections, high resistance to reversion and high abrasion resistance.

Main applications:

    · tire sidewalls

    · conveyor belts

    · tire treads & retreads

    · footwear soles

    · golf balls
