Property:

AA/AMPS is the copolymer of 2-acrylamido 2-methylpropane sulfonic 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. In particular, for calcium phosphate, calcium carbonate, and zinc scale. When built with organophosphines, the synergic effect is obvious.

AA/AMPS copolymer is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitors and dispersants on a high concentration index.

Uses:

AA/AMPS copolymer is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitors and dispersants on a high concentration index.

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

AA/AMPS can also be used as dyeing auxiliaries for textile.
