The halogenation of butyl rubber, with either chlorine or bromine, significantly increases cure reactivity, provides compatibility with unsaturated polymers, and enhances adhesion as compared to regular butyl rubber. Significant improvements in heat, ozone, flex fatigue resistance and compression set can be achieved through the selection of appropriate compounding ingredients and curing systems.
The versatility and properties of halobutyl rubber have led to significant growth in the use of butyl-type polymers in a diverse range of tire and non-tire applications.
Bromobutyl vs. Butyl and Chlorobutyl
Bromobutyl has two natural points of reference, namely: (1) butyl rubber, of which it is a modification, and (2) chlorobutyl, to which it is analogous. In each case, bromobutyl can be said to have several properties in common and to offer several advantages of varying degree.

Because of the faster cure rate of bromobutyl, direct substitution of bromobutyl in chlorobutyl compounds frequently results in reduced scorch times which, in some cases, result in unacceptable factory processing. In these cases, satisfactory processing is readily achieved by adjusting curative types and/or levels.
