Styrene-Butadiene Rubber (SBR)

one of the most widely used synthetic rubbers in the world. It's a copolymer made from two monomers: styrene and butadiene. This combination gives SBR a balance of properties that make it especially useful in a variety of industrial and consumer applications.

Key Properties:

- Good aging stability when protected with additives.
- Moderate tensile strength and flexibility, though not as high as natural rubber.
- Poor resistance to oils, ozone, and UV, so it's often blended or treated for specific uses.

SBR was originally developed during World War II as a substitute for natural rubber and was marketed under the name Buna S—a nod to its butadiene (Bu), sodium (Na), and styrene (S) components.
