Product Description

Aa/amps - acrylic acid-2-acrylamido-2-methylpropane sulfonic acid copolymer ?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. specification: items index appearance colorless or light yellow viscous liquid solid content % 40 min free monomer (as aa)% 0.8 max density (20?)g/cm3 1.15 min ph(1% solution) 3.5-4.5 viscosity mpa.s 90-200 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. package and storage: normally in 250kg net plastic drum, ibc drum can also be used as required.storage for ten months in room shady and dry place.
