PBR 1220

High-Cis Polybutadiene rubber “1220” is produced by a technology of solution polymerization based on Ziegler-Natta (Cobalt) catalyst. It has more than 96% of 1.4 Cis content and very low glass transition temperature.
Cured “1220” has excellent properties such as abrasion resistance, tear strength, resilience, weathering resistance and low rolling resistance (good fuel economy) due to its low glass transtion temperature (Tg typically <-90 °C).
