Polyisobutene

Polyisobutene, also known as polyisobutylene or butyl rubber, is a globally recognized material characterized by its chemical resistance, resistance to various weather conditions and long service life. This polymer is obtained by polymerising isobutene and its chemical structure gives it a number of unique properties that are valued in many industries. Polyisobutene is characterized by its great flexibility and sealing properties, and this is what makes it widely used.

An important target for polyisobutene is the automotive industry. Its main role here is as the main component of tyres and other sealing elements. Due to its flexibility and durability, it is also used in the construction of various machines and vehicles. In the food industry, this chemical is less used, but is found in food adhesives, where it acts as a bonding and sealing element. Polyisobutene is also used in the cosmetics industry, where it is found in a range of cosmetic products, including lipsticks and lip balms. In the packaging industry, on the other hand, it is used for the production of various packaging materials, mainly in combination with other polymeric materials. Finally, it is worth noting that polyisobutene is also used in the chemical industry as an additive in lubricants and oils, where it improves their sealing and lubricating properties.
