What is Sodium Polyacrylate
Sodium polyacrylate, a sodium salt derived from polyacrylic acid, acts as a superabsorbent polymer capable of retaining substantial water quantities. Renowned for its exceptional water-absorption capability, it finds diverse applications.
In hygiene items like diapers, incontinence pads, and feminine hygiene products, sodium polyacrylate is frequently used. Its swift liquid absorption and retention help maintain dryness and prevent leaks.
Additionally, it serves agriculture as a soil conditioner and water retention agent. By absorbing water, it bolsters soil’s water-holding capacity, minimizing irrigation needs, and enhancing plant growth in arid or drought-prone regions.
What is Sodium Polyacrylate Used for
- Absorbent hygiene products: Used in diapers, adult incontinence products, and feminine hygiene products for enhanced absorbency.
- Agriculture: Improves soil water retention and promotes plant growth in arid or sandy soils.
- Water treatment: Acts as a flocculant and coagulant to remove impurities in water treatment processes.
- Industrial processes: Used as a viscosity modifier, binder, and dispersant in adhesives, coatings, and detergents.
- Personal care products: Functions as a thickening agent, stabilizer, and texture enhancer in gels, lotions, and creams.
- Chemical spill control: Absorbs and contains chemical spills to prevent hazardous material spread.
How Does Sodium Polyacrylate Work
Sodium polyacrylate utilizes its distinct water-absorbing capacity. It’s a superabsorbent polymer with the capability to absorb water greatly exceeding its own weight.
When immersed in water, sodium polyacrylate goes through hydration. Its polymer chains possess hydrophilic sections that attract and link water molecules via hydrogen bonds. This interaction results in water molecules being assimilated and confined within the polymer structure.
Sodium polyacrylate showcases a network of interconnected polymer chains constituting a gel-like substance when hydrated. This gel effectively confines and immobilizes the absorbed water, preventing leakage.
Its water-absorbing qualities stem from its osmotic pressure creation. Elevated concentrations of sodium ions within the polymer gel generate an osmotic gradient, drawing water molecules into the gel matrix.
The price can vary depending on factors such as the purity, grade, quantity, and supplier. Market conditions and demand also influence the price. It is recommended to contact chemical suppliers or distributors for the most accurate and up-to-date pricing information.
The chemical formula is (C3H3NaO2)n, where “n” represents the number of repeating units in the polymer chain. It is a sodium salt of polyacrylic acid, derived from the polymerization of acrylic acid monomers.
