Polybutadiene Rubber (PBR) 1220 Product Description
Polybutadiene Rubber (PBR) 1220 is a synthetic rubber that is primarily composed of polybutadiene, a polymer made from the monomer butadiene. This particular grade, PBR 1220, is known for its excellent resilience, low-temperature flexibility, and high abrasion resistance. It is produced through anionic polymerization, which results in a high molecular weight and a low glass transition temperature. PBR 1220 is widely used in various applications due to its unique properties, making it a preferred choice in the rubber industry.
The rubber exhibits outstanding mechanical properties, including tensile strength and elongation at break, which contribute to its durability and longevity in demanding environments. Additionally, PBR 1220 has a low rolling resistance, making it an ideal material for tire manufacturing. Its compatibility with various fillers and additives allows for customization in formulations, enhancing its performance in specific applications.
