CAS No.: 9003-04-7
Polyacrylic acid sodium is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. Polyacrylic acid sodium can disperse the microcrystals or micro sand of calcium carbonate, calcium phosphate, and calcium sulfate.
PAAS chemicals are used as scale inhibition and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

40%, 45% Polyacrylic Acid Sodium are supplied.
Polyacrylic acid sodium can be used as a scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems. Dosage should be in accordance with water quality and equipment materials.
When polyacrylic acid sodium (PAAS) used alone, 2-15mg/L is preferred. When polyacrylic acid sodium used as a dispersant, the dosage should be determined by experiment.
