Nonionic Polyacrylamide (NPAM)
CAS Number: 9003-05-8
Nonionic polyacrylamide is a high-molecular-weight polymer that carries no ionic charge, making it effective in high-salt or extreme-pH environments where ionic flocculants may underperform. It acts primarily through bridging mechanisms to aggregate suspended solids. This product is widely used in mining, coal washing, and neutral to acidic wastewater treatment.
