?

History of PBR as a Versatile Material

?

Polybutadiene rubber (PBR) is a versatile material used across various industries. It has a rich history dating back to the early 1900s when pioneering chemists first synthesized polybutadiene. However, it wasn't until the mid-20th century that PBR gained significant importance in the global market, revolutionizing the rubber industry. Over time, technological advancements and research have led to the development of various PBR grades to meet different industry needs.?

?

Production Process?

?

PBR is produced through the polymerization of butadiene monomers, using either solution or emulsion polymerization processes. Solution polymerization occurs in a solvent, while emulsion polymerization disperses the monomers in water with emulsifiers. These methods produce high-quality PBR with properties tailored to specific applications.?

?

Grades of PBR

?

PBR is available in different grades based on molecular structure, polymerization method, and specific characteristics.?

?

The main grades include:

?

??High-cis PBR
