Isobutylene Isoprene Rubber (IIR). Butyl is a common term used for the isobutylene isoprene elastomer. As the name implies, butyl is comprised of isobutylene with a small amount of isoprene. It is known for its excellent resistance to water, steam, alkalis, and oxygenated solvents. Another outstanding characteristic is low gas permeation. Butyl is capable of providing high energy absorption (dampening) and good hot tear strength. 2, record 4, English, - butyl%20rubber
