Key Benefits
The key advantage of Polybutadiene Rubber1220(PBR) lies in its outstanding dynamic performance and exceptional durability, offering a balance of engineering excellence and operational cost savings.
Low Hysteresis and Energy Efficiency: Polybutadiene Rubber1220(PBR)'s very low hysteresis significantly reduces energy loss during repeated deformation cycles. For tire manufacturers, this means reduced rolling resistance, translating to lower fuel consumption and a longer range for electric vehicles. Its excellent thermal stability minimizes the risk of structural degradation, such as casing fatigue, enhancing both safety and longevity.
Superior Abrasion and Wear Resistance: Products made with Polybutadiene Rubber1220(PBR) maintain their structural integrity even in high-friction conditions. This makes it an ideal material for components subjected to heavy wear, such as tire treads, industrial wheels, mechanical transmission parts, and heavy duty rubber tracks. Its high resilience also provides excellent shock absorption, making it well suited for applications like sporting equipment and vibration damping components where impact resistance is critical.
Cold Climate Flexibility: Featuring a remarkably low glass transition temperature (approximately -106°C), Polybutadiene Rubber1220(PBR) remains flexible in extremely cold conditions. This attribute is especially valuable for winter tires, outdoor mining equipment, and automotive parts exposed to harsh temperature variations, ensuring reliable, crack-resistant performance when other elastomers could become brittle.
Efficient Compounding and Curing: The clean and uniform polymer structure of Polybutadiene Rubber1220(PBR) (characterized by low gel content and minimal impurities) enhances curing efficiency and mechanical strength when combined with fillers. This leads to less material waste, smoother manufacturing processes such as extrusion and molding, and highly uniform finished products.
Enhanced Multi-Polymer Blending: When used in multi-polymer formulations, Polybutadiene Rubber1220(PBR) serves as a reinforcing agent. Blended with natural rubber or SBR, it significantly improves properties like tear resistance, tensile strength, and flex life. This makes it an invaluable ingredient for demanding applications, including heavy-duty conveyor belts, large industrial tires, and engineered rubber components requiring both superior strength and robust dynamic performance.
