PBR Polybutadiene rubber

CHARACTERISTICS OF PBR IRAN BUTADIENE RUBBER

Iran polybutadiene rubber containing a polymer obtained by block or graft polymerization of cis-1,4-polybutadiene with syndiotactic (syn)-1,2-polybutadiene, alone or blended with the other diene rubber, said syn-1,2-polybutadiene being crystallized and in a short fiber-like shape, and a breaking resistance characteristic and reinforcement characteristic being considerably improved by specifying the diameter and length of said short fiber, which is suitable for various parts of tire or industrial materials, and further relates to a composition of said polybutadiene rubber to which a carbon black is added for preferably used as a chafer or tread of tire, and still further relates to said composition to which a carbon black and an antioxidant are added for preferably used as a rubber blend composition for side wall.

High-Cis Polybutadiene rubber “ATDM 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 “ATDM 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 <–90˚C).

APPLICATION OF PBR BUTADIENE RUBBER

ATDM 1220 is appropriate for rubber compounds used in the production of tire, floor coverings, footwear, children toys, rubber hose, belts and golf balls.
