Polybutadiene Rubber

Polybutadiene Rubber is a key raw material for industries requiring long service life and dynamic performance. Commercial Polybutadiene Rubber is available in several grades, including high cis, low cis, and medium cis types, as well as linear and branched structures designed for specific processing and end-use requirements. Its major applications include tire treads and sidewalls, conveyor belts, hoses, footwear soles, golf balls, vibration dampers, and various molded rubber goods. The material is composed primarily of polybutadiene polymer chains, often compounded with carbon black, oils, antioxidants, and curing agents to enhance performance. Key technical properties include high elasticity, excellent wear resistance, low glass transition temperature, good fatigue resistance, and strong impact performance at low temperatures. Polybutadiene Rubber also demonstrates good compatibility with natural rubber and other synthetic rubbers such as SBR and NBR, enabling flexible blending for optimized formulations.
