Polyisobutylene (PIB) Market is Projected to Reach US$ 4.47 Million by 2035, Driven by Automotive and Industrial Demand

The global polyisobutylene (PIB) market is poised for steady growth over the next decade. Valued at approximately US $ 2.59 million in 2025, the market is projected to expand at a compound annual growth rate (CAGR) of 5.6%, reaching US $ 4.47 million by 2035.

The upward trajectory of the PIB market is driven by increasing utilization across various industrial segments. Notably, hydrophobic PIB has become a preferred material in tire manufacturing-highlighted by its applications in tubeless tires, inner tubes, and fuel additives-due to its enhanced impermeability, flexibility at low temperatures, and moisture resistance.

These properties contributed significantly to the sector's exponential growth observed in 2024, particularly within the automotive, construction, and adhesives industries.

With the automotive industry gearing up production to satisfy increasing global demand for vehicles, especially commercial and passenger vehicles, PIB found much greater relevance.
