Polyacrylic acid (PAA) is innoxious and soluble in water. The PAA polymer can be used without scale sediment in alkaline and high-concentration situations. Polyacrylic acid can disperse the microcrystals or micro sand of calcium carbonate, phosphate, and sulfate. Polyacrylic acid is used as a scale inhibitor and dispersant for circulating cool water systems, papermaking, weaving, dyeing, ceramic, painting, etc.
