Poly Epi-Amine is also known as Poly(Dimethylamine-co-Epichlorohydrin). It is a water-soluble cationic polymer of differing molecular weights. This cationic polyamine works effectively as primary flocculants and charges neutralization agents in liquid-solid separation processes in a wide variety of industries.

Poly(Dimethylamine-co-Epichlorohydrin) has a strong electrolyte without foam. It is non-toxic and tasteless, stable, insensitive to pH value, temperature, with anti-chlorine, high-temperature, high-pressure, and high-speed shear resistance.

Poly Epi-Amine is used as a mixture compatible with polymeric aluminum for wastewater treatment of turbid river and tap water etc.

Poly(Dimethylamine-co-Epichlorohydrin) should be diluted to the concentration of 0.5%-0.05% (based on solid content). When Poly Epi-Amine is used to treat different wastewater, the dosage is based on the turbidity and the concentration of the water.

Packing and Storage:

Poly Epi-Amine should be packed 200kg/plastic drum or 1000kg/IBC drum or customers’ required.

200l plastic drum  1000l IBC

Should be stored in cool (4-30ºC) to avoid frozen and heat. We certify that Poly Epi-Amine in the correct storage will meet sales specifications for12 months from the date of manufacture.
