Polyacrylic Acid Sodium (PAAS)
Product Model:[CAS No.] 9003-04-7
CAS No.  9003-04-7 
Structural Formula:

PAAS is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. PAAS can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAAS is used as scale inhibition and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.
