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.

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. It works by destabilizing suspended particles and negatively charged water-soluble substances through electro-neutralization and adsorption bridging effects, enabling rapid flocculation and sedimentation of contaminants in water.
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 under virtually all water quality conditions — from strongly acidic to strongly alkaline environments — without loss of performance.
Q
Is PDADMAC safe for use in personal care and daily chemical products?
Yes. PDADMAC is odorless, tasteless, and non-toxic, making it suitable for use in daily chemical products such as shampoos and soaps. It helps improve product texture, reduces static electricity, and enhances overall usage stability.
Q
What are the available packaging specifications for PDADMAC?
PDADMAC is available in 50kg and 200kg plastic drums to accommodate various procurement volumes. It should be stored in a cool, dry indoor environment. Under proper storage conditions (no delamination or caking), the shelf life is 24 months.
Q
What are the main differences between the 60% and 65% effective content grades?
Both grades share the same appearance (colorless to pale yellow transparent liquid), pH range (3–7), and cationic ionicity. The primary difference lies in the effective content: the standard grade contains 60 ± 0.5%, while the high-concentration grade contains 65 ± 0.5%, offering greater treatment efficiency per unit volume for demanding applications.
Q
Can PDADMAC be used in textile and paper manufacturing industries?
Yes. In the textile industry, PDADMAC serves as an aldehyde-free, pollution-free fixing agent that forms a dense protective film on fabric surfaces to improve dyeing and color-fixing results. In paper manufacturing, it is used as a retention and drainage aid to significantly improve paper formation quality.
