Products Description
Poly(diallyldimethylammonium chloride) (PDADMAC, CAS#26062-79-3) is a water-borne cationic polyelectrolyte widely adopted for flocculation applications. Its synthesis relies on radical polymerization of diallyldimethylammonium chloride (DADMAC), with organic peroxide compounds applied as polymerization catalysts. The polymer demonstrates full miscibility with water, yet it cannot be dissolved in ethanol, aromatic hydrocarbons and other organic solvents. The material carries a very high positive charge density, enabling powerful neutralization of negatively charged species. It is resistant to hydrolysis, maintains consistent properties under shifting pH conditions, and offers good tolerance to chlorine exposure.

Products Application
Boasting superior cationic polymer characteristics, PDADMAC covers extensive application scenarios throughout diverse industries:
Water & Wastewater Treatment: A powerful cationic flocculant tailored for municipal and industrial wastewater streams. It excels at colour removal, organic contaminant abatement and enhancing sludge dewatering capacity.
Papermaking: Captures harmful anionic impurities; serves as retention‑drainage auxiliary agent, and accelerates the curing reaction of AKD sizing agents.
Textile Dyeing: Functions as a zero‑formaldehyde dye‑fixing agent for textile colour fixation.
Oil Production: Performs as clay stabilizer within drilling fluids and cationic modification additive for fracturing processes.
Daily Chemicals & Cosmetics: Grants conditioning and static‑eliminating effects in shampoo as well as skin‑care products.
