Main Application：An agent for complexation, EDTA is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making and oil-field. It is also used as detergent for boiler cleaning and reagent in chemical analysis.
1． High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production.
2．Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner.
3．Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer.
4．Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
5． Textile dyeing and printing: EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric.
Packing：PP bag, 25kg/bag. 20MT / 20’ FCL, 18 MT / 20’ FCL if palletized, or packed as client's request.
