About Styrene Butadiene Rubber. Styrene Butadiene Rubber (a.k.a. SBR, SBR Latex) is a synthetic polymer made of monomers 1,3-butadiene and styrene. In the copolymer generated, the butadiene molecule may assume three different forms, according to the way it is connected to the styrene component: (1) Cis 1,4-Butadiene; (2) Trans 1,4-Butadiene; and (3) Vinyl Butadiene. It represents by far the biggest market share between synthetic elastomers produced worldwide. This elastomer offers excellent abrasion resistance, excellent water resistance, good physical properties and easy processing. These properties vary depending on the molecular weight and styrene to butadiene ratio. There's two main Styrene-Butadiene polymer types: Styrene-Butadiene Latex and Styrene-Butadiene Rubber (SBR). SBR has a higher butadiene content than Latex and this makes it more elastic-like.
Chemical Formula. (C8H8)x(C4H6)y
Commercial Grades. Grades vary in molecular weight and in styrene content (typically between 23 and 40%)
Uses. Tires manufacturing represent the main application for Styrene-Butadiene Rubber, but, according to the properties of the specific grade produced, SBR is also used in several application. SBR grades produced by hot emulsion process are still employed in specific applications such as adhesives and flow modifiers for other elastomers, due to its good processing characteristics. SBR grades produced by cold emulsion present superior mechanical characteristics, such as abrasion resistance. They are used in numerous applications, for instance, car and light truck tires, footwears, pharmaceutical and food contact articles, conveyor belts, and even chewing gums. Solution polymerization processes generate SBR grades suitable for high performance applications, including tires with superior wet grip and high resistance shoe soles.
