Polyacrylic Acid (PAA)
CAS No.: 9003-01-4 
Structural Formula:

Product performance:
PAA is innoxious and easily dissolved in water. It can use and scaling under the condition of alkaline and medium multiple.
PAA can disperse the microcrystals or microsand of calcium carbonate、calcium phosphate and calcium sulfate, then play a role of scaling. PAA is a common dispersant and has better dispersion effect on iron oxide and calcium carbonate.
