The global polyisobutylene market size was USD 3.1 billion in 2024, and the market size is predicted to reach USD 5.3 billion by 2032, advancing at a CAGR of 7.2% during 2025-2032.
The market for polyisobutylene has grown considerably in the automobile, construction, and manufacturing industries. PIB's air-tightness, flexibility, and aging resistance have caused the demand for tubeless tires, adhesives, and sealants to rise. PIB also has widespread application as a lubricant additive due to expanded industrial output andinvestment across industries. China's government aimed at more than 6% economic growth in 2020-2021 and industrial production growth of 35.1% in 2019-2021, expected to further propel PIB demand, especially in lubricant additives. China's strong industrial output is expected to further drive the growth of the PIB market. In addition, China's manufacturing production grew by 7% YoY and retail sales gained 5.5% YoY in the early part of 2025. This reflects the strength of China's manufacturing sector, one of the driving forces for PIB demand.
The Asia-Pacific is likely to be the flagship growth market for PIB in the future because of strong demand from key industry segments such as automotive, building, cosmetics, and aerospace from India, Japan, and China. APAC also boasts a large and low-cost manpower base and adequate factory space. A move of the manufacturing base to emerging markets such as China and India is set to drive additional PIB market expansion, with both nations at the forefront of demand growth within the region.
The medium category held the larger market share, of 55%, in 2024. due to its multitude of applications across the fields of lubricants, adhesives, and sealants.
These sectors are leading contributors to PIB demand, especially automotive, construction, and industrial applications. The combination of versatility of medium molecular weight PIB and its balance of viscosity and processing properties makes it the most popular. Since medium molecular weight PIB will be in continued demand as the automobile and construction industries grow, its position as the largest is assured.
The low category will grow at a higher CAGR, of 8%, during the forecast period, because they produce more efficiency. This is due to the growing demand for tubeless tires in the automotive sector and adhesives in packaging and construction, where low molecular weight PIB is employed to enhance the adhesion characteristics and offer greater flexibility. Furthermore, increasing automotive industry in the Asia-Pacific region, where there has been an expansion in the production of commercial vehicles, is driving demand for low molecular weight PIB. Furthermore, low molecular weight PIB is extremely favored for applications involving quick curing times and good processability, which also fuels its growth in niche industrial applications.
The molecular weights analyzed here are:
The adhesives & sealants category held the larger market share, of 45%, in 2024. Adhesives and sealants based on PIB provide better air-tightness, flexibility, and aging resistance, which are essential characteristics for various sectors. The increasing need for high-performance sealants in commercial structures, infrastructure development, and vehicles, especially with the increase in tubeless tire demand, is making this application the largest in consumption and market share.
The lubricant additives category will grow at a higher CAGR, of 8%, during the forecast period, owing to their superior air-tightness, flexibility, and resistance to aging characteristics. Demand for high-performance sealants in commercial buildings, infrastructure development, and automobiles, especially with tubeless tire demand, is fueling this growth. It is stimulated by world industrial expansion and increasing vehicle manufacturing, especially in the Asia-Pacific region. PIB-based lubricant additives enhance viscosity, stability, and performance in automotive and industrial equipment. As the world's industries focus on energy efficiency and sustainability, PIB's contribution to lubricant performance will continue to be a leading growth driver.
The applications analyzed here are:
The C-PIB category held the larger market share, of 60%, in 2024. Its wide-ranging applications keep C-PIB at the forefront in terms of both production and consumption. With its established presence and strong demand in key industrial sectors, especially in regions like Asia-Pacific and North America, C-PIB is firmly positioned as the top player in the PIB market.
The HR-PIB category will grow at a higher CAGR, of 8.5%, during the forecast period, as it caters to specialized fields such as automotive fuel systems and high-performance lubricants. Such consumption will only increase as industries shift their focus to products with higher efficiency, durability, and environmental friendliness. The new focus on sustainable and energy-efficient alternatives, especially in the automobile and energy industries, will most notably drive the market for HR-PIB, making it the most rapidly expanding category of the PIB market.
The products analyzed here are:
The transportation category held the larger market share, of 55%, in 2024. The automotive industry is booming, particularly in emerging markets, which is driving up the demand for PIB in tire manufacturing. When it comes to durability and performance, PIB is a game-changer. Its unique properties make it essential for tire inner liners, helping to keep air in and improve fuel efficiency. But PIB isn't just for tires, it's also found in a range of automotive lubricants and sealants, which only adds to its popularity.
The industrial category will grow at a higher CAGR, of 9%, during the forecast period, as the surge in construction activities around the globe is pushing up the need for PIB-based adhesives and sealants. One of the best things about PIB is its versatility. It's used in a variety of industrial applications, including coatings and insulation materials, which is why it's being adopted so quickly. Moreover, about sustainability is that PIB is increasingly being incorporated into eco-friendly industrial products, aligning perfectly with the global push.

The APAC region held the largest market share, of 45%, in 2024, and will grow at a higher CAGR, of 10%, during the forecast period. China plays an important role with its strong automotive, construction, and industrial sectors as the government’s initiatives for infrastructure development are projected to support economic development of these industries.
The Chinese and Indian auto makers increasingly use more environmentally friendly materials for tire manufacturing and other auto components, PIB's position as a green polymer could further expand. Because of the government measures and financing to maintain its development rate, China's construction business is expected to grow faster than those of other countries. According to the National Development and Reform Commission (NDRC), the Chinese government authorized 26 infrastructure projects worth USD 142 billion in 2019. Similarly, the Communist Party of China declared in 2020 that their investment of USD 142 billion investment in Chinese infrastructure projects, and the growing automobile industry will make a large contribution to PIB consumption in the region.
Furthermore, construction firms, such as China State Construction Engineering Corporation (CSCEC) and China Railway Construction Corporation Limited (CRCC), consume massive volumes of PIB-based adhesive and sealants. such as hot-melt sealants, primarily for woodwork laminating applications, thereby propelling polyisobutylene demand in the country. Growing industrialization in emerging economies such as India, Vietnam, and Indonesia will also make a contribution to the high growth of the region.
The regions analyzed in this report are:
The polyisobutylene market is fragmented, with major companies like ExxonMobil, BASF, INEOS, and Lubrizol holding significant shares due to their advanced technologies. The market also includes regional players catering to specific applications like lubricants, adhesives, and sealants. ExxonMobil is a major contributor, leveraging its infrastructure and research capabilities. The PIB market is expansive, with applications in automotive, construction, manufacturing, and cosmetics. The growing demand for tubeless tires, lubricants, and adhesives is driving market growth. As industrial production increases globally, consumption is expected to rise, creating opportunities for both established and new players.
