Properties:

AA-AMPSA is a copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid. Because of including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA-AMPSA 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-AMPSA is particularly suitable to be used in water quality of high pH, high alkaline and high hardness, it is one of the ideal scale inhibitor and dispersant on high concentration index.

Usage:

AA-AMPSA can be used as scale inhibitor and dispersant in open circulating cooling 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-AMPSA can also be used as dyeing auxiliaries for textile.
