Product Description

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.

Frequently Asked Questions
What is PDADMAC and how does it work as a flocculant?
PDADMAC (Poly(diallyldimethylammonium chloride)) is a cationic linear polymer that works by destabilizing suspended particles and negatively charged substances in water through electro-neutralization and adsorption bridging effects, enabling efficient flocculation, decolorization, sterilization, and organic matter removal.
What is the effective pH range for PDADMAC application?
PDADMAC has an extremely wide pH adaptation range of 0.5 to 14, allowing it to function stably under virtually all water quality conditions, from strongly acidic to strongly alkaline environments.
What are the available concentrations and key specifications of PDADMAC?
PDADMAC is available in two grades: 60±0.5% and 65±0.5% effective content. Both grades appear as a colorless to pale yellow transparent liquid, with a pH range of 3–7 (10g/L aqueous solution) and cationic ionicity.
Is PDADMAC safe for use in daily chemical products?
Yes. PDADMAC is odorless, tasteless, and non-toxic, making it safe and environmentally friendly for use in daily chemical products such as shampoos and soaps, where it helps improve texture, reduce static electricity, and enhance product stability.
How should PDADMAC be stored and what is its shelf life?
PDADMAC should be stored in a cool, dry indoor environment. Under proper storage conditions — with no abnormal phenomena such as delamination or caking — the product has a shelf life of 24 months.
What packaging options are available for PDADMAC?
PDADMAC is available in two packaging options: 50kg plastic drums and 200kg plastic drums, suitable for various order quantities and application scales across industrial and commercial users.
