PBR
Polybutadiene was one of the first elastomers that was invented. It consists of polybutadiene, an elastomer (elastic polymer) built up by chemically linking multiple molecules of butadiene to form giant molecules, or polymers.
Production
Butadiene is a reactive colourless gas produced by the dehydrogenation of butene or butane or by the cracking of petroleum distillates. The gas is dissolved in hydrocarbon solvents and polymerized to polybutadiene by the action of anionic or Ziegler-Natta catalysts.
Properties
- High Elasticity
- Low temperature properties
- Wear resistance
- Low hysterisis
- Good flexibility at ambient temperatures
- High abrasion resistance in severe conditions
- Low rolling resistance
Applications
The major use of polybutadiene rubber is in tires. It goes into sidewalls and treads.To optimize performance such as traction, rolling and abrasion resistance, it is typically compounded with other elastomers such as natural rubber and SBR. Other applications are golf ball cores, inner tubes of hoses for sandblasting, and covers for pneumatic and water hoses. Polybutadiene is also used as a toughening agent in plastics
