Poly(diallyldimethylammonium chloride) PDADMAC Supplier and Factory in China - High Quality and Competitive Prices
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.

Daily Chemicals: Used in products such as shampoos, soaps, etc., to improve texture, reduce static electricity, and enhance usage stability.
High-end Additive Manufacturing: Used in the production of paper retention and drainage aids, significantly improving paper formation; used in the production of oilfield drilling fluid treatment agents, regulating drilling fluid performance.
Packaging and Storage
Packaging: The product is packed in 50kg or 200kg plastic drums.
Storage: Store in a cool and dry indoor environment, with a shelf life of 24 months (when no abnormal phenomena such as delamination or caking occur).
Frequently Asked Questions
Q
What is PDADMAC and how does it work as a flocculant?
PDADMAC (Poly diallyldimethylammonium chloride) is a cationic linear polymer that works through electro-neutralization and adsorption bridging mechanisms. It rapidly destabilizes and flocculates suspended particles and negatively charged water-soluble substances in water, while also providing decolorization, sterilization, and organic matter removal functions.
Q
What pH range is PDADMAC effective in?
PDADMAC has an extremely wide pH adaptation range of 0.5 to 14, allowing it to function stably across virtually all water quality conditions — from strongly acidic to strongly alkaline environments — without loss of performance.
Q
What are the main application areas of PDADMAC?
PDADMAC is widely used in water treatment (flocculation and decolorization), textile dyeing and printing (as an aldehyde-free color fixing agent), daily chemical products (shampoos, soaps), and high-end additive manufacturing including paper production and oilfield drilling fluid treatment.
Q
Is PDADMAC safe to use and environmentally friendly?
Yes. PDADMAC is odorless, tasteless, and non-toxic, making it both environmentally friendly and safe for use in a wide range of industrial and consumer applications. Its low required dosage also contributes to reduced chemical waste and lower sludge production.
Q
What packaging options are available and what is the shelf life?
PDADMAC is available in 50kg or 200kg plastic drums. When stored in a cool and dry indoor environment, the product has a shelf life of 24 months, provided no abnormal phenomena such as delamination or caking occur.
Q
What are the available concentration grades of PDADMAC?
PDADMAC is offered in two concentration grades: 60±0.5% effective content and 65±0.5% effective content. Both grades appear as colorless to pale yellow transparent liquid, are cationic in nature, and have a pH range of 3–7 (measured as a 10g/L aqueous solution).
