Sodium Polyacrylate CAS 9003-04-7

What Sodium Polyacrylate Is

Sodium Polyacrylate is the sodium salt polymer of acrylic acid, CAS 9003-04-7, sold as powder, liquid. Carboxylate groups make it an anionic polyelectrolyte. Low molecular weight chains adsorb on particles, keeping solids dispersed, stopping scale, while it thickens and suspends in detergents. Crosslinked grades hold much water. It serves water treatment, paints, food, agriculture. UATChem supplies it, with molecular weight and viscosity on COA.

Water Treatment, Detergent, Paint and Absorbent Uses

• Scale and dispersion. It stops carbonate and sulfate scale in cooling water and boilers, often blended with polymaleic acid.
• Detergent and personal care. It thickens and suspends in liquid detergents and care products.
• Paint, paper, textile and food. It disperses pigments, aids paper and textile work and thickens foods.
• Absorbent grades. Crosslinked high molecular weight grades hold water for agriculture and hygiene products.

Typical Specifications

Molecular weight, viscosity, solids and particle size vary by grade and are reported on the COA and TDS, while handling is covered by the SDS. The table below identifies the material.

Packaging, Documents and Ordering

• Powder orders ship in 25 kg bags and FIBC ton bags, and liquid grades in drums, matching the photos. Keep the powder sealed, dry and away from moisture.
• Every lot comes with a COA, TDS and SDS covering molecular weight and viscosity.
• Samples are available for evaluation. To quote, UATChem needs the grade, quantity, packing and destination port.

FAQ

Q: What is sodium polyacrylate used for?

A: It inhibits scale and disperses solids in water treatment, thickens detergents, disperses pigments and serves food uses.

Q: Is sodium polyacrylate a scale inhibitor?

A: Yes, low molecular weight chains adsorb on scale crystals and stop them growing in cooling water and boilers.

Q: How is sodium polyacrylate packed?

A: UATChem supplies the powder in 25 kg bags and FIBC ton bags, sealed and dry, with COA, TDS and SDS, and liquid in drums.

Q: Does sodium polyacrylate absorb water?

A: The soluble grades dissolve and thicken water, while crosslinked grades hold water for agriculture and hygiene.
