Sodium polyacrylate is a superabsorbent polymer commonly used in products like diapers and absorbent pads. It can absorb and retain large amounts of liquid relative to its own weight, making it effective for controlling moisture. This property is due to its unique chemical structure, which allows it to swell when in contact with water. In addition to personal care products, sodium polyacrylate is also used in agriculture to improve soil moisture retention. It helps reduce water usage and supports plant growth by keeping the soil hydrated. Its versatility makes it valuable in various industries, including healthcare and environmental management.
