China PDADMAC Suppliers - High-Quality Poly(diallyldimethylammonium chloride) from Reliable 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.

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. It destabilizes suspended particles and negatively charged substances in water, causing them to aggregate into larger flocs that settle quickly, thereby purifying the water.
Q
What pH range is PDADMAC effective in?
PDADMAC has an extremely broad pH adaptation range of 0.5 to 14, allowing it to function stably across a wide spectrum of water quality conditions — from strongly acidic to strongly alkaline environments — without loss of performance.
Q
Is PDADMAC safe for use in daily chemical products such as shampoos?
Yes. PDADMAC is odorless, tasteless, and non-toxic, making it suitable for use in daily chemical products including shampoos and soaps. It helps improve product texture, reduce static electricity, and enhance overall usage stability, while being environmentally friendly.
Q
What are the available packaging options and 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 are observed.
Q
What is the difference 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 is the active polymer concentration: the 60% grade contains 60 ± 0.5% effective content, while the 65% grade contains 65 ± 0.5%. The higher concentration grade may offer greater cost efficiency in applications requiring higher dosing performance.
Q
Can PDADMAC be used in textile dyeing as a fixing agent?
Yes. PDADMAC is used as an aldehyde-free and pollution-free fixing agent in textile dyeing and printing. It forms a dense protective film on the fabric surface, improving dye uptake and color fastness without introducing harmful aldehyde compounds, making it a safer and more environmentally responsible alternative to traditional fixing agents.
