Polybutadiene Rubber (BR), the most elastic rubber type, is a polymerized butadiene built up by chemically linking several molecules of butadiene to form giant molecules, or polymers. Polybutadiene Rubber (BR) provides strong abrasion resistance, excellent elastic properties, good resistance to low temperatures and low heat build-up.
Polybutadiene Rubbers (BR) are made either with high cis content (95 to 97 percent) or with only 35 percent cis content along with 55 percent trans and 10 percent side vinyl.
The main applications in which Polybutadiene (BR) is being used are:
- Retread compounds
- Conveyor belts
- Cable insulation
- Footwear production
