Superabsorbent Polymers: High-Performance Materials for Hygiene and Agriculture
Superabsorbent polymers (SAPs) are highly specialized materials capable of absorbing and retaining extremely large quantities of liquid relative to their own weight. Typically made from crosslinked polyacrylate or polyacrylamide structures, these polymers can absorb hundreds of times their mass in water or aqueous solutions. This remarkable ability to retain moisture even under pressure makes SAPs invaluable in a wide range of industrial, medical, agricultural, and consumer applications.
In the personal care industry, SAPs are most commonly used in diapers, adult incontinence products, and sanitary napkins, where their high absorption capacity and gel-forming ability provide comfort, hygiene, and leakage protection. When incorporated into these products, SAPs quickly absorb fluids and transform them into a gel-like substance, locking moisture away from the skin and reducing the risk of irritation or rashes.
In agriculture and horticulture, SAPs are utilized to improve soil water retention, reduce irrigation frequency, and support plant growth in arid…
