AA/AMPS, AMPS Copolymer
Properties:
AA/AMPS is the copolymer of 2-acrylamido 2-methylpropane sulfonic acid (AMPS). Due to including the 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 for use in water quality of high pH and 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 textiles.
