Styrene Butadiene Rubber (SBR) is the abbreviation of Polymerized Styrene Butadiene Rubber. Styrene Butadiene Rubber is the backbone of the rubber industry, is the largest general-purpose synthetic rubber varieties, but also one of the earliest industrialized production of synthetic rubber varieties.
According to the polymerization process, SBR is divided into emulsion styrene butadiene rubber (ESBR) and solution styrene butadiene rubber (SSBR). Compared with the solubilized SBR process, the emulsion SBR process is more advantageous in terms of cost savings, and about 75% of the global SBR plant capacity is based on the emulsion SBR process. Emulsion SBR has good overall performance, mature process, widely used, capacity,
