Polybutadiene Rubber

Polybutadiene rubber (BR, PBR) is one of the most frequently-used synthetic rubber in rubber industries, which is sometimes used as a substitute for natural rubber (NR). It is produced either by anionic polymerization or by coordination polymerization of 1,3-butadiene typically in a non-polar solvent. It has high abrasion resistance, high resilience, good low temperature properties characteristics. There are two types of polybutadiene rubber available at Yusheng, they are BR9000(Nickel Catalyst) and BR9104(Neodymium catalyst).
