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.
Storage:Be stored in dry and ventilated warehouse. Avoid direct sunshine,breakage of the bags, humidity and contamination, and handle with care.
