Polyacrylamide is, simply called PAM, a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields. There are three categories of anionic, cationic and non-ionic type.

1) Cationic Polyacrylamide
Solid Content : 90% min
ion activity: 20%-60%
Molecular weight (million): 8-14
Dissolving time (h): <1.0
PH Value:5-8
Residual monomer <0.05%
Insolubles:<0.2%
2)Anionic Polyacrylamide
Molecular weight: 5-22 million
Solid content:90% min
Hydrolyzing degree:10-20%, 20-30% or 30-40%
Dissolving time: 2 hours max


3)Nonionic Polyacrylamide
Solid content:90% mini
Ionization:>3%
Solubility h:1.0
PH Value:1-8
Residue content:<0.05%

PAM are mainly used for oil recovery, sugar-making, coal washing, ore dressing, paper-making, paint, sewage treatment and so on.
