Properties: DTPA is white crystal powder dissolved in hot water and aqueous alkali. It is lightly soluble in cold water, insoluble in organic solvents, for example, alcohol and ether. Melting point: 230℃
Uses: DTPA is efficient chelating agent. It is widely applied in acrylic fiber manufacturing as color inhibitor, in paper making industry, as water softening agent, as textile auxiliary agent, as food additive, as stabilizing agent of drugs. It is also used in water treatment, textile, paper making, rubber, photography, petroleum and chemical fields.
Packaging: 25kg inner plastic bag and outer woven bag or fiber drum, or for demand
Storage: Should be preserved in dry, ventilated and cool warehouse; should be separate with alkaline matter and strong oxidant
