Poly-1 butene (PB-1), also known as polybutene-1, is a high-performance thermoplastic polymer belonging to the polyolefin family. Produced through the polymerization of 1-butene with stereospecific catalysts, PB-1 exhibits a highly isotactic structure, resulting in exceptional crystallinity, high melting points (120โ130ยฐC), and superior mechanical properties.
Thanks to its excellent chemical resistance, sealing properties, and durability, PB-1 finds applications across multiple industries, including packaging, plumbing, automotive, and medical devices.
Market Size 2024: USD 2.14 Billion
Forecast 2034: USD 4.53 Billion
CAGR (2025โ2034): ~7.8%
The market is expected to witness significant growth, driven by expanding demand for advanced packaging solutions, robust construction activity, and increasing adoption in automotive and healthcare industries.

PB-1 has excellent heat-sealing properties and strong compatibility with polypropylene, making it highly suitable for sheets, containers, and films.
Growth of e-commerce and online retail is fueling demand for reliable packaging.
Example: Amazon announced plans to achieve $80 billion in cumulative e-commerce exports from India by 2030, highlighting the rising need for advanced packaging materials.
The building & construction industry is among the largest consumers of PB-1, especially in plumbing systems due to its resistance to high temperature and pressure.
Applications include hot and cold water piping, district heating systems, and smart city infrastructure.
PB-1 is increasingly used in fuel tanks and automotive components due to its chemical resistance and high-temperature stability.
Example: Chery (China) expanding in South Africa and Indiaโs Make-in-India initiatives are boosting automotive production, thereby driving PB-1 demand.
High production costs due to specialized processing requirements.
Complex supply chains and reliance on a few producing countries.
Geopolitical tensions (e.g., USโChina trade disputes) could disrupt raw material supply.
Competition from substitutes like cross-linked polyethylene (PEX) and ethylene-vinyl acetate (EVA).
Medical Devices: Growing use of PB-1 in flexible, durable, and biocompatible medical components.
Automotive Expansion: New manufacturing plants and EV adoption will expand applications.
APAC Growth: Strong chemical production base in China and India along with heavy infrastructure investments will keep Asia-Pacific at the forefront.
Asia-Pacific is projected to dominate due to:
Strong chemical manufacturing infrastructure in China, India, and South Korea.
Government investments, like BCPLโs INR 387 crore project in India (2023) to set up new PB-1 facilities.
Rapid expansion of automotive and construction industries across the region.
The competitive landscape includes:
Reliance Industries Ltd., LyondellBasell, BASF SE, Braskem S.A., SABIC, INEOS, Shell Chemicals, Mitsui Chemicals, Borealis AG, and others.
The poly-1 butene market is set for healthy growth, supported by packaging demand, construction activity, and automotive expansion. However, industry players must navigate supply chain complexities, production costs, and substitute competition to maximize opportunities. With Asia-Pacific leading the charge, PB-1 is positioned as a critical material shaping the future of packaging, plumbing, and automotive industries worldwide.
