Chemicals Industry Today
High Purity Isobutylene Market was valued at USD 7.10 billion in 2024 and is projected to reach USD 14.60 billion by 2035, growing at a CAGR of 6.77%
The high-purity isobutylene (HPIB) market plays a pivotal role in modern polymer chemistry and specialty chemicals manufacturing. HPIB serves as a vital feedstock for producing butyl rubber, polyisobutylene (PIB), methyl tert-butyl ether (MTBE), and various lubricants, additives, and medical-grade elastomers. The demand surge for high-performance materials in automotive, healthcare, and industrial sectors continues to accelerate global market growth.
Market Overview
The Global High Purity Isobutylene Market was valued at USD 7.10 billion in 2024 and is projected to reach USD 14.60 billion by 2035, growing at a CAGR of 6.77% during the forecast period 2025–2035.
High-purity isobutylene, typically with a purity above 99.5%, is derived from isobutane dehydrogenation or refinery streams and refined using catalytic and separation technologies. Its applications extend from fuel additives and polymers to adhesives and sealants, thanks to its chemical stability, high reactivity, and compatibility with diverse formulations.
Rising demand for butyl rubber in tire manufacturing (for air retention and durability) and polyisobutylene in lubricants and adhesives are key growth drivers. Moreover, the expanding use of pharmaceutical-grade isobutylene in medical elastomers and stoppers underscores the market’s diversification.
