Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer(AA/AMPS)

【CAS】40623-75-4

Structure:

            

1,Properties:

AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When built with organophosphines, the synergic effect is obvious. AA/AMPS is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitor and dispersant on high concentration index.

2,Specification: Conform to  HG/T3642-1999

3,Application range:

AA/AMPS can be used as scale inhibitor and dispersant in open circulating cool water system, oilfield refill water system, metallurgy system and iron & steel plants to prevent sediment of ferric oxide. When built with organophosphorines and zinc salt, the suitable pH value is 7.0~9.5. AA/AMPS can also be used as dyeing auxiliaries for textile.

4,Package and Storage:

Normally In 25kg,200 kg or 250kg net Plastic Drum, or packing as customers’ request.Storage for ten months in room shady and dry place.
