Propeties of Polyisobutene useful to the Automotive Industry

Anti-corrosion - Polyisobutene is highly effective at preventing corrosion. Making it a valuable material in the automotive industry. Its visco-elastic nature allows it to form a protective barrier shielding the metal surfaces from environmental factors that may impact its integrity. PIB prevents the onset of rust, therefore extending the lifespan of the automotive components.
Self-Healing Capabilities - These properties of Polyisobutene are particularly beneficial in the automotive applications because any damage that may occur to the Polyisobutene, it can "flow" together to fill the gap and restore the protective barrier. This ensures long-term protection with less frequent maintenance required.
Chemical Resistance - Polyisobutene is chemically inert and does not alter or allow for chemicals to break down or pass through it. Protecting the substrate from chemical ingress and damage.
Hydrophobic Nature - The molecular state of Polyisobutene is a very stable non-polar structure, therefore making it hydrophobic.
Long-Term Performance - Polyisobutene does not cure, it is stable and durable ensuring long-lasting protection against corrosion. This then enhances the reliability and longevity of vehicles.

Underbody Coatings - Polyisobutene as a coating can protect the underbody of vehicles from road salt, water and debris due to its chemical resistance, hydrophobic and self-healing nature.
Seam Sealants - Grade specific Polyisobutene can be used as a sealant for the seams and joints in vehicles to prevent water ingress and corrosion. It remains flexible to adapt to environments where stress occurs.
Wire and Cable Insulation - PIB is used for insulating the wires and cables, protecting the electrical system from moisture and corrosion.
