Ion Exchange Resins Market size was estimated at USD 1,111.17 Mn in 2021, growing at a CAGR of 3.8% during the forecast period 2022-2028. The global ion exchange resins market is poised to grow at a significant CAGR owing to increase in the purification of water and waste water treatment. For instance, most of the industries are focusing on wastewater treatment and approximately 60% of water is reusable. Moreover, due to rapid urbanization and increase in demand for purified water expected to create better market opportunities for the market players. In addition, approval for newer products anticipated to upsurges the revenue growth of the market. For instance, in April 2016, Jacobi’s resinex division received French Ministere des Affaires et de la Sante (FMASS) approval for Resinex KW-H used in removal of temporary hardness and other dealkylation process in potable water supplies. Furthermore, expansion of business by market players is a strategy to dominate the ion exchange resins market. For instance, in April 2013, Lanxess expanded its ion-exchange resins facilities in Leverkusen by investing € 10 Mn in a new product line for weakly acidic cation exchange resins for water treatment.Ion exchange resins are the polymers that act as a medium in the ion exchange process. Most of the ion-exchange resins are based on the cross-linked polystyrene. Ion-exchange resins are classified into anion-exchange resins and cation-exchange resins. Ion exchange resins are widely used in the purification, separation, and decontamination process. Applications of ion exchange resins include water purification, water softening, and metal separation, production of high-purity water, juice purification, sugar manufacturing, and pharmaceutical purification among others. In November 2017, Purolite Life sciences collaborated with Repligen Corporation to provide ion exchange agarose resins and high-flow Praesto Protein A affinity with Opus pre-packed chromatography columns.
