- Styrene-butadiene or styrene-butadiene rubber (SBR) is a synthetic rubber copolymer consisting of styrene and butadiene. It has good abrasion resistance and good aging stability when protected by additives, and is widely used in car tires, where it may be blended with natural rubber.
- It was originally developed prior to World War II in Germany,[1]. Industrial manufacture began during World War 2, where it was used extensively by the USA to replace the Far-East natural rubber supplies captured by the Japanese.
- Styrene butadiene latexes usually have a resin content of about 50%. The styrene/butadiene ratio varies from 54:46 to 80:20.
