Styrene-Butadiene rubber (SBR) Styrene-butadiene rubber (SBR) exhibits a structural relationship between styrene and butadiene, making it a widely used copolymer. This polymer is highly prevalent in the rubber industry due to its outstanding physical and mechanical properties. It finds applications in automotive and industrial rubber production, engineering structures, automotive manufacturing, and textiles. Key characteristics of SBR include flexibility, resistance to oil, water, and heat, as well as durability against corrosion and abrasion. Therefore, a significant portion of rubber production is dedicated to this polymer. SBR latex exhibits desirable wear resistance, with over 70% of produced SBR used in tire manufacturing, another 15% in mechanical components, and nearly 10% as latex. The ratio of styrene to butadiene can significantly influence the properties of SBR latex. Higher styrene content results in a harder rubber. SBR burns in flames and continues to burn after the flame is extinguished. Its flame appears yellow-orange and produces a slight crackling sound, emitting smoke that is whitish-gray.
