AA AMPS Copolymer

Properties:

AA/AMPS is the copolymer of acrylic acid and 2-acrylamide-2-methylpropane sulfonic acid. 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 copolymer is suitable to be used in water quality of high pH and high alkaline. AA/AMPS copolymer is one of the ideal scale inhibitor and dispersant on high concentration index.

Usage:

AA/AMPS can be used as a 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 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.
