Top 10 Companies in the Global Hydrolyzed Polymaleic Anhydride (HPMA) Market (2026): Market Leaders Powering Water Treatment Innovation

MARKET INSIGHTS

The Global Hydrolyzed Polymaleic Anhydride (HPMA) market size was valued at USD 435.2 million in 2024. The market is projected to grow from USD 462.8 million in 2025 to USD 684.5 million by 2032, exhibiting a CAGR of 5.8% during the forecast period.

Hydrolyzed Polymaleic Anhydride (HPMA) is a low molecular weight polymer widely recognized for its excellent scale inhibition and dispersion properties. This synthetic polymer is highly effective in preventing the precipitation of inorganic salts, such as calcium carbonate and calcium sulfate, in aqueous systems. Its primary functions include acting as a threshold inhibitor and a dispersant for suspended particles like clay and metal oxides.

The market growth is primarily driven by its extensive use in water treatment applications across power generation, oil and gas, and industrial manufacturing sectors, where it is critical for preventing scale formation in cooling water and boiler systems. Furthermore, increasing environmental regulations demanding efficient water management and the expansion of the detergent and cleaning industry are significant contributors. The Asia‑Pacific region, particularly China, is a dominant force due to rapid industrialization and stringent environmental policies. Key players such as Dow, Nippon Shokubai, and BASF (which acquired parts of Solvay’s polyamide business, enhancing its polymer portfolio) continue to innovate, focusing on developing more efficient and environmentally friendly formulations to maintain a competitive edge.
