Polybutadiene Rubber / BR

With a high-cis structure, BR has excellent physical properties of vulcanized rubber, including excellent abrasion resistance, dynamic performance, and low temperature performance. It also has excellent processability, demonstrating stable processing performance across a wide range of working temperatures. It is used in various types of rubber products such as tires and belts, and is also used in golf balls because of its high rebound resilience.
