Specification :

CAS: 40623-75-4
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.

Usage:
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.
