High molecular weight PIB dominates the global market mainly because of its critical use in tyres, inner liners, and vibration-dampening components. It is irreplaceable for enhancing fuel efficiency in automobiles and prolonging the life cycle of components due to its impermeability to any gas and oxidative degradation. The demand for this PIB grade is further strengthened by the ever-increasing production of electric vehicles requiring better materials for vibration isolation and sealing. The proactive ability of high molecular weight PIB to resist mechanical stressing while remaining flexible gives great performance advantages that competitors have found very hard to imitate. Overall, this segment will continue to be the leader in the PIB market, firmly entrenched within the automotive supply chain and industrial elastomers.

Adhesives and Sealants emerge as fast-growing end-use categories, driven by construction and packaging growth.
