PBR Polybutadiene rubber
What is PBR Polybutadiene Rubber
PBR polybutadiene rubber is a highly versatile material that delivers excellent performance in numerous industries. By polymerizing cis-1,4-polybutadiene with syndiotactic (syn)-1,2-polybutadiene, either on its own or blended with other diene rubbers, it provides superior breaking resistance and reinforcement properties. This unique structure improves the rubber’s mechanical performance, especially when manufacturers adjust the length and diameter of the short, fiber-like structures. Consequently, PBR becomes ideal for various applications requiring durability, strength, and flexibility.
In particular, PBR is widely used in tire production, especially for tire chafers, treads, and sidewalls. These applications benefit from its impressive wear resistance and durability, making it an excellent choice for products that need to withstand demanding conditions.
High-Cis Polybutadiene Rubber 1220
Basekim’s 1220 high-cis polybutadiene rubber sets the industry standard for quality and performance. It is produced using advanced solution polymerization technology with a Ziegler-Natta (Cobalt) catalyst. As a result, 1220 contains over 96% cis-1,4 content, giving it outstanding elasticity and resilience. Moreover, the high cis content leads to a very low glass transition temperature (Tg), ensuring excellent performance even in the harshest conditions.
Upon curing, 1220 demonstrates several key advantages, such as remarkable tear strength, abrasion resistance, and weathering resistance. Furthermore, its low rolling resistance significantly improves fuel efficiency, making it a highly sought-after material for tire manufacturers. Thus, it helps produce tires that not only last longer but also enhance fuel economy.
Applications of Butadiene Rubber
The applications of PBR polybutadiene rubber span across various industries, thanks to its versatile and durable properties. In the tire industry, it plays an integral role in enhancing the overall performance of tires. Its low rolling resistance contributes to better fuel efficiency, while its high abrasion resistance ensures long-lasting durability, even under demanding driving conditions.
In addition to tires, PBR is extensively used in the production of floor coverings, footwear, rubber hoses, belts, and golf balls. The rubber’s flexibility, resilience, and wear resistance make it the ideal choice for these applications. Notably, PBR is also commonly used in the manufacturing of children’s toys, where its safety, durability, and long-lasting qualities are paramount.
Typical Physical Properties of 1220
Basekim ensures that 1220 polybutadiene rubber meets rigorous quality control standards. The key physical properties of 1220 include:
- Mooney viscosity between 41 and 49 MU (ASTM D1646).
- A minimum cis content of 96% (internal method).
- Volatile material content of no more than 0.75% and ash content of under 0.3% (ASTM D1416).
- Tensile strength of at least 150 Kgf/cm³ and elongation at break exceeding 440% (ASTM D412).
These properties guarantee reliable, high-performance results in a wide range of demanding industrial applications, providing customers with consistent and durable rubber products.
Packaging, Transportation, and Storage of PBR
Basekim packages 1220 polybutadiene rubber in 35 kg bales wrapped with polyethylene film to ensure protection during transport. Each crate typically contains 36 bales, totaling approximately 1260 kg. The rubber is transported using covered road trucks, railway carriages, or standard shipping containers, ensuring safe and secure delivery.
When it comes to storage, 1220 should be kept in sheltered conditions, away from direct sunlight and radiant heat sources. Additionally, the storage temperature should not exceed 30°C to preserve the rubber’s properties and ensure its long-term quality.
