Product Overview
Polyacrylamide (PAM) is a high-molecular-weight, water-soluble synthetic polymer produced by the polymerization of acrylamide monomers. It exhibits outstanding flocculation, thickening, drag reduction, and bridging properties. Depending on the ionic functionality, PAM is classified into four main types: anionic, cationic, nonionic, and amphoteric. Due to its versatile charge characteristics, PAM is an essential processing aid in wastewater treatment, enhanced oil recovery, papermaking, mining, and many industrial solid–liquid separation processes.
