Ion Exchange Resins Market

The ion exchange resins market is projected to reach USD 2.97 billion by 2031 from USD 2.34 billion in 2026, at a CAGR of 4.8%. Global demand for ion exchange resins is rising, driven by expanding water treatment activities, particularly in emerging economies. Growing use in end-use industries such as power, chemicals & petrochemicals, food & beverage, and pharmaceuticals is further fueling demand. As water scarcity intensifies and wastewater discharge standards become more stringent, industries increasingly require high-efficiency water treatment and demineralization solutions. Demand is also increasing for resins used in water treatment and purification, as well as in separation processes in the pharmaceutical and biotechnology sectors. In power generation, plants require high-purity water for condensate polishing and boiler feedwater treatment, further supporting demand for these materials.

The ion exchange resins market is dominated by key manufacturers, including DuPont (US), LANXESS (Germany), Mitsubishi Chemical Group Corporation (Japan), Samyang Corporation (South Korea), Ecolab (US), JACOBI RESINS (Sweden), Ovivo (Canada), IEI (India), Thermax Limited (India), and Sunresin New Materials Co., Ltd. (China), among others. From January 2023 to September 2026, these players pursued product launches, deals, and expansions to strengthen their market share and global reach. In July 2026, DuPont launched a Direct Lithium Extraction portfolio comprising more than 20 products, including DuPont AmberLite ion exchange resins. The portfolio combines ion exchange resins with sorbents, nanofiltration, reverse osmosis, and ultrafiltration to help extract, purify, and concentrate lithium from brine. The launch expands the use of ion exchange resins for Direct Lithium Extraction.
