Polyacrylic Acid (PAA)

CAS No. 9003-01-4

Synonyms:

PAA; Polyacrylic Acid; Acrylicresin; acrylicacidresin; acrylicacid polymers;

polyacrylateelastomers; acrysola;

Structural Formula:

Properties:

PAA is innoxious and soluble in water, it can be used in situations of alkaline and high

concentration without scale sediment. PAA can disperse the microcrystals or microsand of calcium

carbonate, calcium phosphate and calcium sulfate. PAA is used as scale inhibitor and dispersant for

circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.
