Product Features
EDTPO is a broad spectrum scale inhibitor. Particularly effective against calcium sulphate and barium sulphate. EDTPO is a powerful complexing agent with a high calcium tolerance. EDTPO is an excellent chelant and also has good chemical and thermal stability. EDTPO has strong metal ion chelating capacity, The complex constant with Cu is the largest in all chelating agents including EDTA.EDTPO can replace EDTA for chelating agent at almost any situation.
EDTPO is a kind of high-pure grade reagent and innocuous. EDTPO 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. EDTPO is used in detergents as an incrustation control agent and for the stabilization of bleach components. EDTPO is also used in oilfield formulations and as a peroxide bleach stabilization agent in textile auxiliaries. EDTPO has a high dispersing power for ceramic slurries and retards setting in building materials.
EDTPO is white crystal powder at room temperature, with melting point 215-217℃, hard to be dissolved in water, the solubility is less than 5% at room temperature, easy dissolved in ammonia.
