High-Quality PDADMAC from Reliable China Suppliers - Leading Factory for Poly(diallyldimethylammonium chloride) Solutions
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.

Application Area
Water treatment: Applied to process steps such as water quality decolorization, flocculation purification, etc., to achieve efficient removal of water pollutants and improvement of water quality.
Textile Dyeing and Printing: Used as an aldehyde-free and pollution-free fixing agent for the color fixing treatment of fabrics, forming a dense protective film on the surface to improve the effects of dyeing and color fixing.
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 destabilizes and flocculates suspended particles and negatively charged water-soluble substances through electro-neutralization and adsorption bridging. It also provides decolorization, sterilization, and organic matter removal functions in water treatment.
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 all water quality conditions — from strongly acidic to strongly alkaline environments — making it highly versatile for diverse industrial applications.
Q
What industries can PDADMAC be used in?
PDADMAC is widely used across multiple industries including water treatment (flocculation and decolorization), textile dyeing and printing (as an aldehyde-free fixing agent), daily chemical products (shampoos, soaps), paper manufacturing (retention and drainage aids), and oilfield drilling fluid treatment.
Q
Is PDADMAC safe for use in consumer products?
Yes. PDADMAC is odorless, tasteless, and non-toxic, making it suitable for use in daily chemical products such as shampoos and soaps. It combines environmental friendliness with safety, meeting the requirements of consumer-facing applications.
Q
What are the available product specifications and packaging options?
PDADMAC is available in two effective content grades: 60±0.5% and 65±0.5%. Both grades appear as a colorless to pale yellow transparent liquid with a pH of 3–7 (10g/L aqueous solution) and are cationic in nature. Packaging options include 50kg or 200kg plastic drums to suit different usage scales.
Q
How should PDADMAC be stored, and what is its shelf life?
PDADMAC should be stored in a cool and dry indoor environment, away from direct sunlight and extreme temperatures. Under proper storage conditions — with no abnormal phenomena such as delamination or caking — the shelf life is 24 months from the date of production.
