SBR (Styrene Butadiene Rubber):

SBR, the common name for Styrene Butadiene Rubber was developed originally to be a viable synthetic replacement for the Natural Rubber used in tires. It is still used in certain automotive applications, but in many cases has been replaced by EPDM materials, which offer better heat and compression set resistance than SBR.

This copolymer of styrene and butadiene is used in general applications where exposure to mineral oils is not required. Originally developed to replace natural rubber, it performs better at high temperatures, although tensile strength, resilience and abrasion resistance are inferior at lower temperatures. SBRs have inferior weathering and chemical resistance to most other elastomers. Typical applications are sealing requirements for hydraulic braking systems.
