Basic information
Poly(diallyldimethylammonium chloride), abbreviated as POLYDADMAC, is a cationic polymer. Its appearance is usually a colorless to light - yellow transparent liquid, which has good water solubility and can quickly dissolve in water to form a stable solution.
Product characteristics
High - efficiency flocculation ability:It can quickly adsorb negatively charged colloidal particles (such as clay, microorganisms, and organic substances) in water through charge neutralization and is widely used in sewage treatment.
Low toxicity and environmental protection:It has better biodegradability than traditional flocculants (such as polyacrylamide) and meets the EU REACH and US EPA standards.
Strong chemical stability:It is not easily hydrolyzed and can still maintain its activity in hard water or high - salt environments.
Main application fields
Product indicators
| Appearance | Solid content % | Viscosity CPS | pH value |
| Colorless to light - yellow transparent liquid | 40±1 | 8000 - 12000 | 5 - 7 |
Storage and transportation
Storage: Keep it in a sealed container away from light and store at 5 - 35℃ (prevent the liquid from freezing);Transport as a non - dangerous product
Industry trends and innovation directions
Green substitution: Gradually replace flocculants containing aluminum/iron salts to reduce the risk of heavy metal residues;
Emerging scenarios:
Reuse treatment of shale gas fracturing wastewater;
Binder for lithium - battery cathode materials (replacing PVDF).
