Application

Sodium polyacrylate serves as a highly effective absorbent, capable of retaining 200 to 300 times its mass in water, making it ideal for managing aqueous-based spills. This organic sodium salt is composed of repeating sodium acrylate units and functions as a retention and slow-release aid for water. Known for its broad range of applications, sodium polyacrylate is extensively used in consumer products due to its unique ability as an anionic polyelectrolyte with negatively charged carboxylic groups along its main chain. Beyond its primary use in absorbing and retaining moisture, sodium polyacrylate also acts as a sequestering agent in detergents. It binds to hard water elements like calcium and magnesium, enhancing the effectiveness of surfactants. While sodium neutralized forms are predominant in industry, variants such as potassium, lithium, and ammonium salts also exist, offering diverse applications across commercial and industrial sectors.
