Styrene Butadiene Rubber (SBR)
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, production and consumption in the first place in the SBR. Oil-filled styrene butadiene rubber has the advantages of good processing performance, low heat generation, good low-temperature flexibility, etc. It has excellent traction performance and abrasion resistance when used for tread rubber, and the plasticity of the rubber is enhanced after oil-filling, which is easy to mix, and at the same time, it can reduce the cost and improve the production.

Styrene butadiene rubber (SBR), also known as polystyrene-butadiene copolymer. Its physical properties, processing performance and product performance is close to natural rubber, some properties such as abrasion resistance, heat resistance, aging resistance and vulcanization speed is more excellent than natural rubber, can be used with natural rubber and a variety of synthetic rubber, widely used in tires, tapes, hoses, wires and cables, medical equipment and the production of a variety of rubber products and other fields, it is the largest general-purpose synthetic rubber varieties.
