Property:

Polyacrylic acid sodium salt (PAAS) is innoxious and soluble in water. It can be used in situations of alkaline and high concentration without scale sediment. This polyacrylic acid salt can disperse the microcrystals or micro sand of calcium carbonate, calcium phosphate, and calcium sulfate. PAAS is used as scale inhibition and dispersant for circulating cool water systems, papermaking, weave, dyeing, ceramic, painting, etc.
