ExxonMobil Chemical invented and patented butyl rubber in 1937.  The motivation to develop a better, less costly synthetic rubber came from a surge in automotive production in the 1920s and 1930s, which generated high demand for tires and inner tubes. 

Compared to natural rubber, the material used at that time, butyl rubber improved the ability to hold air, flex and dampen vibration. As a result, it soon became the leading material for inner tubes, and – some 20 years later in the 1950s – halogenated butyl helped enable the development of the tubeless tires.
