PBR 1220


PBR 1220 is a polybutadiene rubber (PBR), 1188 CENTER has the opportunity to distribute and export the product directly from TAKHTE JAMSHID PETROCHEMICAL through its commerce services according to the specific and technical properties as follows.


Moreover, it is a kind of polybutadiene rubber (PBR) that is created by a solution polymerization process using a cobalt catalyst. It possesses a high cis-1,4 content of at least 96%, which offers it high elasticity and stability to dynamic pressure. It also includes a non-staining high-quality stabilizer system.


PBR 1220 possesses different uses in rubber hoses and other mechanical rubber materials. It upgrades the abrasion stability, crack resistance, and thermal build-up under dynamic load when blended with natural rubber or styrene-butadiene rubber. It can be used as an additive for upgraded mechanical durability. High-Cis Polybutadiene rubber “1220” is made by a technology of solution polymerization in terms of on Ziegler- Natta (Cobalt) catalyst. It possesses higher than 96% of 1,4 Cis content and less glass transition temperature. The product has great attributes such as abrasion resistance, tear strength, resilience, weathering resistance, and low rolling resistance (good fuel economy) based on its low glass transition temperature.


PBR 1220 is fine for rubber compounds used in items such as tires, floors, shoes, different kinds of toys for kids, rubber hoses, belts, or even golf balls. The technical specifications of PBR 1220 vary and it depends on the industry and the usages.
