Butyl rubber (IIR), the chemical name of which is Isobutylene-isoprene
copolymer is actually the copolymer of isobutylene and a small amount of
isoprene. Also known as polyisobutylene, this rubber was first
commercialized in 1943. Resulting from low levels of unsaturation between
long polyisobutylene segments, the primary quialities of butyl rubber are
excellent impermeability or air retention and good flexible properties. The
first major use of butyl rubber was Tire innertubes, and this continues to
be a significant market today.
Applications of Butyl Rubber

Processing and Vulcanization of Butyl Rubber
applications, butyl rubber must be compounded and vulcanized to yield
useful, durable end use products. This is same for all other rubbers as
well. Grades of Butyl are developed to meet specific processing and property
needs, and hence a range of molecular weights, unsaturation, and cure rates
are available commercially. Both the end use properties and the processing
equipment are important in determining the right grade of Butyl to be used
in a specific application. The selection and ratios of the proper fillers,
stabilizers, processing aids and curatives play vital roles in both how the
compound will process and how the end product will behave.
