Polybutadiene Rubber

Polybutadienerubber (BR, PBR rubber) 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 rubberavailable at Yusheng, they are BR9000(Nickel Catalyst) and BR9104(Neodymium catalyst).
