Usage of  2NA EDTA 99%

1. High molecular chemical industry: EDTA  2NA is used as polymetization activator for butyl bezene latex, 

and polyreaction terminator in acrylic fibre production.

2.Daily chemicals: EDTA 2NA  is used as additive to detergent, skin cream and hair-conditioner.

3.Paper- making: EDTA 2NA 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 2NA 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 2NAwill promote colour ability of the dyestuff and brightness of the 

dyed fabric
