EDTMPS

EDTMPS (Ethylene Diamine Tetra‑Methylene Phosphonic Acid Sodium) is supplied as a clear yellow to umber transparent liquid. The compound carries CAS No. 1429‑50‑1, molecular formula C6H12O12N2P4Na8 and a molecular weight of 612.13 g·mol⁻¹. Supplier data state an appearance of clear yellow‑to‑umber liquid with a density of at least 1.25 g cm⁻³ at 20 °C. The active component concentration is specified as a minimum of 30 % by weight.

The formulation contains at least 10 % organic phosphonic acid (as PO₄³⁻) and limits phosphorous acid (as PO₃³⁻) to a maximum of 5 % and phosphoric acid (as PO₄³⁻) to a maximum of 1 %. The pH of a 1 % water solution is reported between 9.5 and 10.5, providing alkaline conditions favourable for scale inhibition. In the water‑treatment industry, EDTMPS is recognised for corrosion inhibition that is three to five times more effective than inorganic polyphosphate, a typical performance benchmark. Typical storage practice is in a dry, shaded area for up to ten months, using standard 250 kg steel drums or interchangeable IBC containers.

The chemical is used as a chelating and antiscale agent in circulating cooling‑water systems, low‑pressure boilers, non‑cyanogen electro‑plating baths and in printing‑dyeing water‑softening processes. Recommended dosage when applied alone ranges from 2 mg L⁻¹ to 10 mg L⁻¹, and it can be blended with HPMA, BTA, PAAS or zinc salts for specialised formulations. Packaging is normally supplied in 250 kg plastic drums, with the exact minimum order quantity, lead time and payment terms to be confirmed directly with the supplier.

Zaozhuang Xintai Water-Treatment Co., Ltd. is listed as an imported supplier based in Shizhong District, Zaozhuang, Shandong Province, China (postal code 277100). The company address is Zhongtai Chemical Industry Park Dongwangzhuang Village Xiwangzhuang Town, and verification signals show a trust tier of harbor while the response rate is currently recorded as zero percent, indicating that inquiries may require follow‑up through the platform’s messaging system.

The supplier’s current listing focuses on the provision of EDTMPS for industrial water‑treatment applications. Packaging is offered in 250 kg drums with the option of IBC containers, but the catalogue does not disclose minimum order quantities, lead‑time estimates or specific quality certifications, so prospective buyers should request certificates of analysis and any relevant environmental compliance documents directly from the supplier.
