HEDP•Na is suitable for acidic scale inhibitor and detergent, can be used for metal surface treatment.

HEDP•Na₂ is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions, it can dissolve the oxidized materials, HEDP•Na₂ can form six-ring chelating compounds with metal ions in water system, Ca₂

HEDP•Na₄ is the sodium salt of HEDP, HEDP•Na₄ is an good scale inhibitor for calcium carbonate, it can be used in low pressure boiler water system, circulating water system, industrial and municipal cleaning water system and swimming

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. 

DTPMP•Na₂ is a scale inhibitor, for barium sulphate in particular and a chelating agent.

DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate.
