Maleic Anhydride Grafted Polybutadiene (MLPB) is a functionalized elastomer where maleic anhydride groups are chemically bonded to polybutadiene chains, enhancing polarity and adhesion for high‑performance tire compounds, adhesives, and coating formulations. Its relevance stems from the growing demand for lightweight, fuel‑efficient vehicles and the need for superior bonding in advanced composites. The Maleic Anhydride Grafted Polybutadiene market size reached approximately USD 500 million in 2025, and the market forecast projects a CAGR of 4.1% from 2026 to 2033, driven by expanding automotive tire production, stringent emissions regulations prompting lighter‑weight materials, and rising adoption in high‑performance adhesives. Key forces shaping the industry include technological advances in solution‑polymerization grafting, regulatory pressure for reduced rolling resistance, and intensified supply‑chain focus on sustainable feedstocks. Asia‑Pacific dominates the market, accounting for over 55% of global consumption, while Southeast Asia emerges as the fastest‑growing sub‑region, propelled by new tire‑manufacturing capacity in Vietnam and Indonesia.
