Styrene Butadiene Rubber (SBR), also known as Buna S, was developed just before WW II and was used extensively by the United States during WW II due to the unavailability of Natural rubber during those years. It is still widely used in tires.

 

SBR is reasonably priced, has good abrasion resistance and fair weathering properties. It is not especially good with chemicals or solvents.

 

The temperature range for SBR compounds is -60° to 250° F. PAI offers Black SBR compounds in a hardness range of 40 to 80 durometer. Some white compounds are also available.
