The polymer polyisobutene is based on isobutene. Polyisobutene is mainly used as a lubricant and fuel additive. Thus, for example, isobutene ensures that combustion engines run efficiently. While maintaining engine performance, this liquefied gas reduces fuel consumption and harmful emissions.
Isobutene-based rubber is also used in the production of tires, hoses or adhesives and sealants. In car tires, butyl rubber is used for air-impermeable inner coatings.
Furthermore, isobutene is also an important intermediate to produce antioxidants.
Isobutene is also essential building block for citral, linalool and geraniol applications. The liquefied gas gives dishwashing detergents, among others, a pleasant citrus, lavender or rose scent. Moreover, isobutene is used for vitamin A synthesis. As you can see, isobutene really is a gas for all occasions.
