About Isobutylene Isoprene Rubber. Isobutylene Isoprene Rubber (a.k.a. IIR) is an organic compound, in the (co)polymer class. IIR is a copolymer, consisting of about 98% polyisobutylene and 2% isoprene. It is a colorless (sometimes faint yellow) material, substitute to natural rubber, and began to be industrially manufactured in the 1940s, as supplies to USA troops in World War II. Currently, butyl rubber has numerous applications, being produced in several molecular weights, and IIR’s halogenated derivates have been growing in production each year.
Chemical Formula. (C4H8)n
Commercial Grades. Isobutylene Isoprene Rubber is available as: latex; stabilized; chlorine-containing elastomer; and low molecular weight (liquid).
Uses. Isobutylene Isoprene Rubber is used mainly in: tire carcasses and linings; electric wire insulation; glove manufacturing; tire inner tubes; latex for paper coating; textile and leather finishing; gas masks and chemical agent protection; gum base; speakers and audio equipment (foam surrounds replacement); self-curing cements; caulks/sealants; encapsulating compounds; adhesives; pharmaceuticals; tire vulcanization; paints; tapes; and roofing/pond membranes.
- Isobutylene + isoprene (precipitation process, using methyl chloride as diluent)
- C5 – C7 hydrocarbon (solvent) + aluminum alkyl halide (initiator)
Derivatives. Isobutylene Isoprene Rubber is used to produce halogenated butyl rubbers.
