Styrene butadiene (SBR)
 
SBR is a low cost, high volume rubber that is available in various ratios of these two monomers. SBR copolymers with a high styrene and low butadiene content can be compounded into high tensile strength, high modulus, high hardness materials without the use of large amounts of fillers. Because of the good abrasion resistance and leather-like properties of these compounds, they are used in the manufacture of shoe soling and floor tile. On the other hand, highbutadiene, low-styrene copolymers offer good flexibility at low temperatures.

Most SBR copolymers are produced in a butadiene/styrene ratio of 77 to 23. In the reinforced formulations, these rubbers have high tensile strength and elongation. They can also be compounded to have good abrasion and tear resistance and low compression set. Special compounding is required for good weatherability.
