Poly Butadiene Rubber ( PBR)

Polybutadiene was one of the first elastomers or tires that was invented, 70% of poly-butadiene is used to make rubber and tire, and 25% to 30% of it is added as an additive to other tires.Polybutadiene Rubber, PBR is the second largest volume synthetic rubber produced, next to styrene-butadiene rubber (SBR).

Polybutadiene rubber, PBR the second largest volume elastomer, accounts for approximately 25 percent of the total global consumption of synthetic rubbers. Due to its very low vinyl content it has a very low glass transition temperature (-90 °C), very high resilience and is probably the most elastic rubber. Polybutadiene Rubber, PBR also has good abrasion and tear resistance as well as low heat buildup, which is important for tire applications. Compared to SBR, it has a lower glass transition temperature, which gives it a lower rolling resistance. However, it has lower friction on wet surfaces than SBRs. For this reason, it is usually blended with SBRs and natural rubbers to achieve the best tire

The Polybutadiene rubber, PBR is and will continue to be a high volume rubber for use in toughened plastics, tires, and golf balls due to its low cost, availability and unique properties.
