Consequently customers use TRINSEO BUNA® cis-132 in tire tread and sidewall compounds, conveyor belts, footwear and in other applications such as golf ball cores where good dynamic properties are sought.

TRINSEO BUNA® cis-132 Polybutadiene Rubber is produced at Trinseo’s world class production facility in Schkopau, Germany resulting in a product of exceptional consistency and quality delivering excellent processability resulting in high degrees of customer satisfaction and loyalty.

TRINSEO BUNA® cis 132 Polybutadiene Rubber is stereo specific 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.

TRINSEO BUNA® cis 132 contains a non-staining stabiliser.

TRINSEO BUNA® cis 132 is widely used in the tyre industry and 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.

The excellent processability properties of TRINSEO´S BUNA® cis 132 makes it a good polybutadiene rubber to be blended with natural rubber and styrene butadiene (SBR), isoprene (IR), nitrile (NBR), or polychloroprene (CR) synthetic rubbers.

Also due to its non-staining stabiliser TTRINSEO´S BUNA® cis 132 is suitable for light-coloured rubber articles also when compounded with selected thermoplastics.
