Butyl rubber (IIR) is a synthetic rubber material known for its excellent chemical and thermal stability. It is usually prepared by anionic polymerization of isobutene and a small amount of isoprene. The main component of butyl rubber is poly (1-hexene), which has a saturated molecular structure, which allows it to maintain good elastic properties at high temperatures and has strong resistance to oxidation, ozone, and other chemical degradation factors.
