PDADMAC Suppliers in China - 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.

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
Q1
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. This causes particles to aggregate into larger flocs that settle quickly, effectively clarifying water.
Q2
What pH range is PDADMAC effective in?
PDADMAC has an extremely wide pH adaptation range of 0.5 to 14, meaning it can function stably under virtually all water quality conditions — from strongly acidic to strongly alkaline environments — without losing its treatment effectiveness.
Q3
Is PDADMAC safe for use in personal care products such as shampoos?
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, reduce static electricity, and enhance overall usage stability.
Q4
What packaging options are available for PDADMAC?
PDADMAC is available in 50kg or 200kg plastic drums to suit different procurement and usage needs. It should be stored in a cool, dry indoor environment. Under proper storage conditions with no abnormal phenomena such as delamination or caking, the shelf life is 24 months.
Q5
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 a colorless to pale yellow transparent liquid with a pH range of 3–7 (measured at 10g/L aqueous solution) and are cationic in ionicity.
Q6
Can PDADMAC be used in textile dyeing and printing applications?
Yes. PDADMAC is widely used as an aldehyde-free, pollution-free fixing agent in the textile dyeing and printing industry. It forms a dense protective film on fabric surfaces, significantly improving dyeing uniformity and color fastness while meeting environmental protection requirements.
