Butyl rubber is a copolymer of isobutylene and isoprene. It has exceptionally low gas and moisture permeability and outstanding resistance to heat aging, weather, ozone, chemical attack, flexing, abrasion and tearing. It is used in many applications requiring airtight rubber. Butyl also has excellent resistance to acids and alkalis. Butyl is not recommended for use when in contact with petroleum oils or fluids. Butyl functions well in temperatures ranging from -60°F to +250°F.
