POLYBUTADIENE RUBBER (BR)
Polybutadiene Rubber (BR) is a diene polymer, it’s a polymer made from a monomer that contains two carbon-carbon double bonds, specifically butadiene.
Features:
– BR are highly elastic and have a very high degree of resistance to dynamic stress, and retain these properties even at extremely low temperatures. Although this is a significant elastomer it is most commonly used as a blend with other rubbers.
Application:
- Conveyor belts
- Footwear sole
- Industrial rubber products
- Rubber flooring
- Gaskets or tubes
