China PDADMAC Suppliers - High-Quality Poly(diallyldimethylammonium chloride) from Trusted Factory
Core Features
High-efficiency flocculation treatment capacity: As a cationic linear polymer, it can quickly destabilize and flocculate suspended particles and negatively charged water-soluble substances in water through electro-neutralization, adsorption bridging and other effects, and also has multiple functions such as decolorization, sterilization, and removal of organic matter.
Low dosage, high efficiency: Low dosage, large flocs formed, fast settling speed, low residual turbidity, and low sludge production, taking into account both treatment effectiveness and economy.
Broad Adaptability: It has an extremely wide pH adaptation range (0.5 - 14) and can stably function under various water quality conditions from strongly acidic to strongly alkaline.
Safety and Environmental Protection: Odorless, tasteless, non-toxic, and combines environmental friendliness with safety.
