Used primarily in the production of superabsorbent polymers, which are essential in hygiene products like diapers and adult incontinence pads due to their ability to absorb and retain large amounts of liquid. It is also utilized in agricultural applications, where it helps in soil conditioning and water retention, improving crop growth in arid regions. In the medical field, it finds use in wound dressings that require high absorbency to manage exudates effectively. Additionally, it serves as a cross-linking agent in various industrial processes, enhancing the durability and performance of materials such as adhesives and coatings.
