Dtpa-5na Paper Chelating Agent (140-01-2)

Name: Diethyienetriaminepentaacetic acid, pentasodium salt
Molecular weight: M=503.25
Main application:
DTPA-5Na, primarily as a metal ion chelator, is widely used in papermaking, textile, food, medicine,
Agriculture, daily necessities and other industries. It's advantages are: (1) has a exceptional strong capacity
On complexing high valence metal ions; (2)the complex has good water solubility; (3)it do not depositing,
Scaling; (5)extraordinary ability to stabilize hydrogen peroxide; (5)adding it before the bleach agent is able to
Improve the whiteness of the fibers.
Packing:
250Kg or 1250Kg per plastic drum, or according to customer's requirements
Storage:
Stored in dry and ventilated warehouse, avoid direct sunlight, remember to push and put gently.
