AA AMPS Copolymer
Properties:
AA/AMPS is the copolymer of acrylic acid and 2-acrylamide-2-methylpropane sulfonic acid. 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 for calcium phosphate, calcium carbonate, and zinc scale.
When built with organophosphines, the synergic effect is obvious. AA/AMPS copolymer is suitable for use in water quality of high pH and alkaline. AA/AMPS copolymer is one of the ideal scale inhibitors and dispersants on a high concentration index.

Uses:
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 organophosphine and zinc salt, the suitable pH value is 7.0~9.5.
AA/AMPS copolymer can also be used as dyeing auxiliaries for textiles.
