Polybutadiene rubber (PBR) is polymerized butadiene. It was one of the first types of synthetic elastomer, or rubber, to be invented. It is very similar to natural rubber, polyisoprene. It is good for uses which require exposure to low temperatures. It is used in blends with other rubber types for improved elasticity, wear resistance and low temperature properties.
The major use of PBR is in tyres with over 70% of the polymer produced going into treads and sidewalls. PBR imparts excellent abrasion resistance (good tread wear), and low rolling resistance (good fuel economy) due to its low glass transition temperature.
PBR also has a major application as an impact modifier for polystyrene and acrylonitrile butadiene styrene (ABS) resin. Apart from tire treads, belts, hoses, gaskets and other automobile parts are also made from polybutadiene, because it stands up to cold temperatures better than other elastomers.
