The invention of butyl rubber in 1937 ushered in an air-barrier rubber that was about ten times less in air permeability than could be obtained in natural rubber and in synthetic high diene rubber, lending to its uses as inner tubes in tires. In the 1950s, halogenated butyl rubber, or halobutyls, were invented that have sufficient tack and cured adhesion to carcass rubber compounds, allowing the development of tire innerliner and tubeless tires (refs. 1 and 2). Although blends of natural and halobutyl rubber were used in the earlier years for tire innerliner to balance cost, processability, tack, adhesion and low temperature properties, tire innerliners are now based ...
