Product Application

1) Water Treatment & Industrial Cleaning - The Largest Application Sector

Scale Inhibition/Dispersion:​ A core component of polymeric scale inhibitors​ widely used in industrial cooling water, boiler water, and reverse osmosis (RO) membrane systems. It effectively disperses microcrystals of calcium carbonate, calcium sulfate, calcium phosphate, and iron oxide, preventing deposition. Its mechanism relies more on the "threshold effect" and crystal distortion than on strong chelation (unlike EDTA).

Detergent Builder:​ In metal cleaners and dishwashing liquids, it helps disperse and suspend soil particles, preventing redeposition.

2) Consumer & Personal Care

Thickener/Rheology Modifier:​ When neutralized and lightly cross-linked (e.g., Carbomer), it is a key gelling and thickening agent​ for transparent gels, lotions, and creams, providing excellent clarity and a non-greasy feel.

Dispersant/Stabilizer:​ Stabilizes solid particles (e.g., abrasives, pigments) in toothpaste, shampoos, and facial cleansers.

Film Former:​ Used in hair styling gels and masks to form flexible films.

3) Paints, Inks & Adhesives

Dispersant:​ Acts as a highly effective polymeric dispersant​ in water-based paints, ceramic glazes, and pigment slurries, stabilizing pigments/fillers, preventing settling, and improving gloss and color strength.

Thickener:​ Modifies rheology for proper flow and anti-sag properties in coatings and adhesives.

Binder Component:​ Used in pressure-sensitive adhesives and paper product binders.

4) Textiles, Dyeing & Leather

Pretreatment & Dyeing:​ Used as a chelating dispersant​ to soften water, disperse dyes, and prevent staining.

Coating & Finishing:​ A component in coating pastes and anti-static finishes.

5）Agriculture

Soil Conditioner/Water Retentive Agent:​ Cross-linked sodium polyacrylate (SAP) can absorb hundreds of times its weight in water, acting as a "mini-reservoir" in soil for drought resistance, seed coating, and growth media.

6) Other Fields

Oil & Gas:​ Used as a fluid loss control agent and viscosifier in drilling muds.

Ceramics:​ Acts as a binder and dispersant for ceramic bodies.

Food Industry:​ Its sodium salt can be used as a food additive (e.g., clarifier, thickener) under strict regulatory limits.
