Polyacrylamide (PAM), Polyacrylamide Powder, Polyacrylamide …
Cationic polyacrylamides (CPAM) are used for emulsion breaking, and for promoting filtration and sludge dewatering. Another common use is oil extraction and recovery. When water is injected into the well, PAM assists in pushing oil locked in reservoirs towards the pump by increasing the viscosity of the injected water.
Polyacrylamide (PAM) For Sale – Water Treatment Chemical
Cationic polyacrylamide is a linear high molecular polymer which is copolymerized by cationic monomer and acrylamide in different proportions by advanced polymerization technology. The cationic polymer has the characteristics of fast dissolution rate, narrow molecular weight distribution and small dosage.
