Increasing Use in Rubber Modification to Strengthen LPBD Market Prospects

The global liquid polybutadiene (LPBD) market was valued at USD 3.3 billion in 2024 and is projected to reach USD 5.3 billion by the end of 2035. The market is expected to expand at a CAGR of 4.4% during the forecast period from 2025 to 2035, driven by growing demand in adhesives, sealants, and rubber modification applications.

Market growth is primarily fueled by the automotive industry's shift toward high-efficiency tires and the increasing use of LPBD as a high-performance additive in thermosetting plastics and coatings. Furthermore, the expansion of the electronics sector—specifically for potting resins and hydrophobic encapsulants—is creating high-value opportunities for manufacturers of specialty grades.

Key Findings of the Market Report

• Tire Manufacturing remains the dominant application, accounting for over 40% of the market share, as LPBD significantly improves tread wear resistance and fuel efficiency.
• The Adhesives & Sealants segment is projected to be the fastest-growing application through 2032, driven by the demand for moisture-resistant bonding in construction and electronics.
• Non-functionalized LPBD currently leads the product segment, though functionalized grades (e.g., Maleic Anhydride Grafted, Hydroxyl-terminated) are gaining traction in aerospace and specialty coatings.
• Asia-Pacific held the largest market share in 2024, representing approximately 43% of global revenue, largely due to robust industrial activity in China and India.

Global Liquid Polybutadiene Market: Growth Drivers

• Fuel-Efficient Tire Demand: Stringent environmental regulations regarding vehicle emissions have pushed tire manufacturers to adopt LPBD-based compounds that reduce rolling resistance without compromising wet grip or durability.
• Electronics & 5G Infrastructure: LPBD's low dielectric constant and low water absorption make it ideal for 5G copper-clad laminates and electrical insulation. The global rollout of 5G is a significant niche driver.
• Sustainable Material Innovation: The industry is pivoting toward "Green LPBD," with major players launching sustainable product lines that utilize bio-based butadiene or recycle waste rubber, catering to the growing "Circular Economy" demand.
• Construction & Infrastructure: In developing regions, the surge in infrastructure projects is increasing the consumption of LPBD-based waterproofing membranes and industrial sealants.

Global Liquid Polybutadiene Market: Regional Landscape

• Asia-Pacific: This region serves as the primary engine for the LPBD market. China and India are major manufacturing hubs for tires and electronics, benefiting from abundant raw material availability and lower labor costs.
• Europe: Europe is a leader in specialty and sustainable LPBD grades. The market is driven by high environmental standards and a strong presence of premium automotive OEMs in Germany and France.
• North America: Growth in this region is centered on the aerospace and defense sectors, where Hydroxyl-Terminated Polybutadiene (HTPB) is used in solid rocket propellants and high-end industrial sealants.

Key Developments

• In November 2024, researchers at Institute of Applied Chemistry, China, prepared high cis-1,4 liquid polybutadiene (cLBR) and polyisoprene (cLIR) using chain-transfer coordination polymerization, and studied their effect on carbon-black filled single polybutadiene (PBR) or a blend of PBR/polyisoprene (PIR) composite. The results showed that wet skid resistance and rolling resistance of vulcanized PBR/PIR composites were significantly improved due to the use of plasticizers cLBR and cLIR, and help in fabrication of “green” tyres by replacing conventional TDAE oil.
• In June 2023, Cray Valley announced its first commercialization of certified renewable LPBD resins for the tire industry. The sustainable raw materials originated from the processing of bio-based or advanced recycling feedstock.
• In June 2022, Evonik's Coating & Adhesive Resins business line introduced a sustainable range of liquid polybutadienes, named POLYVEST eCO. The company stated that the use of sustainably produced butadiene for manufacturing POLYVEST eCO resulted in reduction in use of fossil raw materials by up to 99.9%.
