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