Polyacrylic acid sodium salt (PAAS, Sodium neutralized polyacrylic acid)

Poly(acrylic acid sodium salt) is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. 
Poly(acrylic acid sodium salt) can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. 
Poly(acrylic acid sodium salt) is used as scale inhibition and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc. 
Poly(acrylic acid sodium salt) can be used as scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems.
Poly(acrylic acid sodium salt) is Sequestering agents in detergents. By binding hard water elements such as calcium and magnesium, the surfactants in detergents work more efficiently.
