Description

Polybutadiene CAS NO 40022-03-5 is a synthetic polymer of butadiene, primarily known for its high resilience and excellent low-temperature flexibility. This versatile elastomer is a critical raw material for producing high-performance rubber products, offering superior abrasion resistance and dynamic properties. It is essential for manufacturers in the tire, automotive parts, and polymer modification industries seeking to enhance product durability and performance.

Application

• Tire Manufacturing: A key component in the production of tire treads and sidewalls, especially for high-performance and winter tires, due to its excellent abrasion resistance and low-temperature flexibility.
• Polymer Modification: Used as an impact modifier for plastics like High-Impact Polystyrene (HIPS) and Acrylonitrile Butadiene Styrene (ABS) to improve toughness and crack resistance.
• Industrial Rubber Goods: Employed in the manufacture of conveyor belts, hoses, gaskets, seals, and other molded or extruded rubber products requiring high resilience.
• Golf Ball Cores: Utilized for its high coefficient of restitution (COR) and energy return properties in the construction of solid golf ball cores.
• Adhesives and Sealants: Serves as a base polymer in formulations for high-strength adhesives, mastics, and construction sealants.
• Footwear: Incorporated into shoe soles and other components to provide durability, flexibility, and slip resistance.
