Butyl Rubber

The molecular structure is essentially a long, saturated chain with occasional isoprene units acting as waypoints for crosslinking. This structure results in a material that is thermoplastic in its raw state but becomes thermoset after vulcanization with sulfur or a resin cure system.

Butyl rubber was first synthesized in the 1940s by a team of researchers at the American chemical company, Standard Oil (now ExxonMobil). The team, led by chemist Robert G. Albanese, discovered that by copolymerizing isobutylene and isoprene, they could create a rubber-like material with exceptional air-tightness and resistance to heat, chemicals, and abrasion. The new material was initially called "butyl rubber" due to its isobutylene content, and it quickly gained popularity in various industrial applications. butyl rubber
