Product Highlights
  • High-cis Neodymium Butadiene Rubber is modified polymeric structure with excellent performance: long service life and high wear resistance, contributing to boost rolling resistance and reduce fuel consumption.
  • High-cis Neodymium Butadiene Rubbers have a narrow molecular weight distribution combined with a low vinyl-content and a very high 1.4-cis content (>97+%).
  • Improved strength, abrasion resistance on its basis and several varieties of products with medium and high Mooney viscosity (45 and 63) result in the performance characteristics improvement and high quality of tires. Sibur technology provides extremely low polydispersity resulting in excellent tire performance .
Features and Benefits
  • Excellent Abrasion Resistance
  • High Resilience, Low Heat Build-Up
  • Good Resistance To Reversion
  • Flex Fatigue Resistance
