AA/AMPS - CAS 40623-75-4

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

CAS 40623-75-4

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, AA/AMPS is one of the ideal scale inhibitor and dispersant on high concentration index.

Specification of AA/AMPS:
Appearance of AA/AMPS: Colorless or light yellow viscous liquid
Solid content of AA/AMPS: 40 % min
Free monomer of AA/AMPS (as AA): 0.8% max
Density of AA/AMPS (20centigrade): 1.15 g/cm3 min
pH of AA/AMPS (1% solution): 3.5-4.5
Viscosity of AA/AMPS: 90-200 mpa.s

Usage of AA/AMPS:
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.

Package and Storage of AA/AMPS:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required.Storage for ten months in room shady and dry place.
