Poly(diallyldimethylammonium chloride）
High-Efficiency Flocculant: As a robust cationic polyelectrolyte, PDADMAC is extensively applied in water treatment and papermaking to facilitate flocculation and eliminate suspended solids.
Strong Cationic Charge: Its long polymer chains carry a high density of positive charges, allowing efficient adsorption and agglomeration of particles in water-based systems.
Wide Industrial Application: Thanks to its excellent versatility, PDADMAC is adopted across numerous industries, especially for enhancing water transparency and supporting solid-liquid separation processes.
Reliable Stability: This product maintains stable performance under regular storage and usage conditions, yet it is incompatible with strong oxidizers and some metallic materials, requiring appropriate operation and storage.
Poly(diallyldimethylammonium chloride) (PDADMAC) is a cationic polymer commonly employed as an effective flocculating agent in multiple industrial applications. It is synthesized through radical polymerization of diallyldimethylammonium chloride monomers, typically using organic peroxides as catalysts.
This synthesis yields long-chain polymer molecules carrying a high density of positive charges, which can effectively adsorb and gather suspended particles in water-based solutions. PDADMAC is widely applied in water treatment, paper production, and other industries that demand particle elimination or flocculation. Its multifunctional performance and stable working properties establish it as an ideal option for improving water quality and supporting diverse solid-liquid separation applications.
