MAIN APPLICATION: An agent for chealte, EDTA is mainly used for water treatment, as an additive to detergent, 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 poiduction.

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 imide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.

5. Textile dyeing and printing: EDTA will promote color ability of the dyestuff and brightness of the dyed fabric.


PACKING:PP bag, 25kg/bag. 20MT / 20’ FCL, 18 MT / 20’ FCL if with pallet packing.


STORAGE: Be stored on the shelf or pallet in dry and ventilated warehouse. Avoid direct sunshine, breakage of the bags, humidity and contamination and handle with care.
