HEDP

Wuxi Lansen Chemicals supplies HEDP as a crystalline powder that can be re‑suspended as a colourless liquid for field use. The active HEDP content is reported at 58‑62 % by weight, matching typical industry specifications for corrosion inhibitors. The material contains a maximum of 2.0 % phosphorous acid (as PO₃³⁻) and up to 0.8 % phosphoric acid (as PO₄³⁻). Additional limits include chloride not exceeding 0.01 % and iron ions capped at 10 ppm.

The product is noted for its stability at temperatures up to 250 °C and resistance to hydrolysis across a wide pH range, characteristics valued by water‑treatment formulators. It is commonly blended with polycarboxylic acids to enhance antiscale performance, and the solid form is packed in either 25 kg polyethylene bags or 200 kg plastic drums, which aligns with standard bulk chemical handling. Typical industry purity for HEDP is ≥ 98 % and moisture content is kept below 0.5 % to ensure consistent dosing.

End‑users such as power‑generation facilities, oil‑field services and low‑pressure boiler operators rely on the 1‑10 mg L⁻¹ scale‑inhibition dose and the 10‑50 mg L⁻¹ corrosion‑protection range. The detergent dosage for textile applications can reach 1 000‑2 000 mg L⁻¹. Packaging options and MOQ are not disclosed in the listing, so buyers should request those specifics directly from the supplier.

Wuxi Lansen Chemicals Co., Ltd is based at Room No 18, 4th Floor, Modern Life Square, 118 South Jiubin Road, Yixing, Jiangsu, China (postal code 214200). The company is recorded as an imported supplier with a harbour‑level trust tier; its platform response rate is currently zero, so direct contact may be required for timely communication.

The supplier lists HEDP for use in cooling‑water systems, oil‑field operations, low‑pressure boilers and also in textile detergent and dye‑fixing applications. While the listing mentions both liquid and solid forms and standard bulk containers, it does not provide details on minimum order quantities, lead times or payment conditions, all of which should be clarified with the supplier before contracting.
