Synthos BUNA™ cis 132 Schkopau High-cis Polybutadiene Rubber (PBR) (discontinued **)
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	BUNA™ CIS 132–Schkopau is a stereospecific butadiene with a high 1,4-cis content. It is manufactured by a solution process using an organo-metallic nickel catalyst which produces a consistent light coloured polymer with low ash content. BUNATM cis 132–Schkopau contains a non-staining stabilizer. Application: BUNATM cis 132–Schkopau is widely used in the tire industry but also in the production of conveyor belts and other rubber articles which are exposed to high cyclical stress. It offers good abrasion resistance, high resilience, low hysteresis, and a low glass transition temperature. BUNATM cis 132–Schkopau offers excellent processability and may be blended with natural rubber and styrene butadiene (SBR), isoprene (IR), nitrile (NBR), or polychloroprene (CR) synthetic rubbers. Due to its non-staining stabilizer BUNATM cis 132–Schkopau is suitable for light-colored rubber articles also when compounded with selected thermoplastics. Synthos acquired the synthetic rubber business from Trinseo in 2021.
