Frequently Asked Questions
Q1
What is PDADMAC and how does it work as a flocculant?
A
PDADMAC (Poly(diallyldimethylammonium chloride)) is a cationic linear polymer that works through electro-neutralization and adsorption bridging mechanisms. It quickly destabilizes and flocculates suspended particles and negatively charged water-soluble substances in water, while also providing decolorization, sterilization, and organic matter removal functions.
Q2
What pH range is PDADMAC effective in?
A
PDADMAC has an extremely wide pH adaptation range of 0.5 to 14, allowing it to function stably under various water quality conditions — from strongly acidic to strongly alkaline environments — without losing its treatment effectiveness.
Q3
What are the available concentrations of PDADMAC and what are their specifications?
A
PDADMAC is available in two concentrations: 60% (±0.5%) and 65% (±0.5%) effective content. Both grades appear as colorless to pale yellow transparent liquids with a pH of 3–7 (measured at 10g/L aqueous solution) and are cationic in nature.
Q4
Is PDADMAC safe for use in personal care products such as shampoos?
A
Yes. PDADMAC is odorless, tasteless, and non-toxic, making it safe for use in daily chemical products including shampoos and soaps. It helps improve product texture, reduces static electricity, and enhances the overall stability of formulations.
Q5
What packaging options are available and how should PDADMAC be stored?
A
PDADMAC is available in 50kg and 200kg plastic drums. It should be stored in a cool, dry indoor environment. The shelf life is 24 months, provided no abnormal phenomena such as delamination or caking occur during storage.
Q6
Can PDADMAC be used in textile and paper manufacturing industries?
A
Absolutely. In textile dyeing and printing, PDADMAC acts as an aldehyde-free, pollution-free fixing agent that forms a dense protective film on fabric surfaces to enhance dyeing and color-fixing effects. In paper manufacturing, it is used as a retention and drainage aid that significantly improves paper formation quality. It is also used in oilfield drilling fluid treatment agents to regulate drilling fluid performance.
