Butyl rubber is a synthetic rubber compound or copolymer composed of isobutylene and isoprene. Isobutylene is a chemical compound consisting of methyl and propylene while isoprene, consisting of methyl and butadiene, makes the rubber unsaturated and able to vulcanize.
Today, butyl rubber is one of the most commonly used synthetic rubber compounds on the market. It is highly impervious to gas and moisture permeation. It is also resistant to oxygenated solvents, alkalis, flexing, and abrasion, which makes it suitable for some applications. Butyl rubbers can provide high energy absorption as well as electrical isolation.
Butyl is also highly resistant to sunlight, ozone, heat ageing, animal and vegetable oils, ammonia, and countless other chemicals. The molecular structure of butyl can even be oriented to resist stress. Butyl has a temperature range of -40 degrees C to +110 degrees C.
Popular applications include inner tubes, o-rings, stoppers for medical bottles, and pharmaceutical supplies.
