Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS)

CAS No.40623-75-4

Other Names: Dispersant 2000, Dispersant 2040

Structural Formula:

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, good dispersity and good scale inhibition for calcium carbonate, zinc scale, calcium phosphate in particular, in the water system. Its excellent dispersing performance enables it to prevent the sedimentation of iron oxide effectively. 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 most ideal scale inhibitor and dispersant on high concentration index.

Specification:

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 textiles and and scale inhibitor for paper pulp in paper making system.

Package and storage:

25kg/30kg/200kg/250kg net in plastic drum or as required.

Storage for twelve months in shady, cool and dry places.
