EDTMPA Ethylene Diamine Tetra (Methylene Phosphonic Acid)


1. General description of EDTMPA Ethylene Diamine Tetra (Methylene Phosphonic Acid)


EDTMPA is white crystal powder at room temperature, with melting point 215-217??, hard to be dissolved in water, the solubility is less that 5% at room temperature, easy dissolved in ammonia. EDTMPA has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA. EDTMPA has high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. EDTMPA is a kind of high-pure grade reagent and innocuous, it can be used as detergent in semiconductor chip to prepare integrated circuit, as carrying agent for radioelement in medical industry, and as agent for inspection and therapy. The chelating capacity of EDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation.


2. Applications for EDTMPA Ethylene Diamine Tetra (Methylene Phosphonic Acid)?


EDTMPA has a strong ability to chelate metal ions, and the complexation constant with copper ions is the largest among all chelating agents including EDTA. EDTMPA is a high-purity reagent and is non-toxic. It can be used as a cleaning agent for semiconductor chips in the electronics industry to manufacture integrated circuits. It is also used as a carrier for radioactive elements in the pharmaceutical industry for the inspection and treatment of diseases. EDTMPA has far more chelating ability than EDTA. With DTPA, EDTMPA can be used almost everywhere where EDTA is used as a chelating agent.

5. FAQ

1. Are you a manufacturer or a trading company?
Yes, We have engaged in water treatment chemicals production for 20 years.

2. Why you choose our water treatment chemicals?
We are the most professional manufacturer of water treatment chemicals in China and have the most advanced manufacturing technology in China. .

3. What is the usage of water treatment chemicals?
In terms of mechanism of action, the role of scale inhibitors is chelating and solubilizing, coagulation and dispersion, electrostatic repulsion, and crystal distortion. In the laboratory evaluation test, dispersion is a remedial measure for cooperating and lattice distortion is the remedy for dispersion.
According to the polymerization components of the scale inhibitor, it can be divided into two categories of natural polymer scale inhibitors and synthetic polymer scale inhibitors. The synthetic polymer scale inhibitors can be further divided into carboxylic acid polymer scale inhibitors, Sulfonate polymer scale inhibitors, phosphorus-containing polymer scale inhibitors and environmentally friendly scale inhibitors.
4. Can you accept OEM order?
Yes, we can. We provide professional water treatment chemicals  OEM Service for our customers.
5. What payment term can you accept?
Usually, we accept 30% T/T deposit, 70% T/T before shipping. Or 50% T/T deposit, 50% T/T against B/L copy. Usually, we could accept L/C, but if you have special cases, we can negotiate.
