CHARACTERSTICS
High-Cis Polybutadiene rubber “SIMONTCO 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 “SIMONTCO 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 transition temperature (Tg typically <–90C).
