Application

The purpose of POLY(ACRYLIC ACID), SODIUM SALT, commonly known as sodium polyacrylate, is to serve as a highly effective absorbent for aqueous-based spills, making it invaluable in various consumer and industrial applications. This compound is a sodium salt of polyacrylic acid, characterized by its macromolecular structure composed of repeating sodium acrylate units. Notably, sodium polyacrylate can absorb 200 to 300 times its mass in water, a property that allows it to function as an efficient retention and slow-release aid for water. It acts as an anionic polyelectrolyte with negatively charged carboxylic groups, enhancing its ability to bind with substances. Widely used in the industry, its primary form is the sodium-neutralized version, though other variants like potassium, lithium, and ammonium salts also exist. In addition to its absorbing capabilities, it functions as a sequestering agent in detergents, where it binds hard water elements such as calcium and magnesium to improve the efficiency of surfactants.
