Butadiene rubber, encompassing both cis-1,4-polybutadiene rubber (BR) and styrene-butadiene rubber (SBR), finds extensive applications across various industries due to its unique combination of properties. Here are some key uses:

Tire Industry: A major application of butadiene rubber is in the production of tires, particularly for automotive vehicles. Cis-1,4-polybutadiene rubber is valued for its high resilience, low rolling resistance, and excellent wear resistance, making it ideal for tire treads. SBR, on the other hand, is often used in tire carcasses and sidewalls due to its balance between cost-effectiveness and performance.
Automotive Components: Besides tires, butadiene rubber is also utilized in manufacturing automotive parts such as bushings, belts, hoses, and seals, where its flexibility, durability, and resistance to abrasion are beneficial.
Sporting Goods: Due to its high elasticity and resilience, butadiene rubber is incorporated into the production of golf ball covers, tennis balls, and the soles of athletic shoes, enhancing performance and durability.
Industrial Applications: It is used in conveyor belts, hoses, and other industrial products that require resistance to wear and tear, oil, and chemicals. Polybutadiene’s excellent mechanical properties make it suitable for these demanding applications.
Adhesives and Sealants: Both BR and SBR contribute to the formulation of adhesives and sealants, improving their tackiness, flexibility, and bonding strength.
Construction Materials: Butadiene rubber is part of the composition of materials like roofing membranes, waterproofing compounds, and coatings, where its weather resistance and durability are crucial.
Electrical Insulation: Its insulating properties make it suitable for use in the production of wire and cable coatings.
Footwear: Polybutadiene rubber is used in the manufacture of shoe soles, providing comfort, shock absorption, and durability.
Medical Devices: Certain grades of butadiene rubber are used in medical applications due to their purity, biocompatibility, and ability to be sterilized.
Modifying Resins: Butadiene rubber can act as a modifier to enhance the toughness and impact resistance of plastics like polyethylene, polypropylene, and polystyrene.
