CAS No.: 40623-75-4

Properties:
AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity), AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When it is compounded with organophosphines, the synergic effect is obvious. AA/AMPS is suitable to use in water quality of high pH and high alkalinity, it is one of the ideal scale inhibitor and dispersant for high cycles of concentration.
