Import Hedp — Buy in Bulk from Supplier in China

HEDP is supplied as a colour‑less or light‑yellow transparent liquid and also as a white crystal powder. The product contains 58‑62 % active HEDP according to the supplier data. Phosphorous acid as PO₃³⁻ is limited to a maximum of 2.0 % and phosphoric acid as PO₄³⁻ to a maximum of 0.8 %. The material shows a density of 1.40 g cm⁻³ and a pH of up to 2 in a 1 % solution.

In the water‑treatment market HEDP is classed as a chelating and scale‑inhibition agent. It is typically blended with polycarboxylic acids to improve performance, and the industry expects a purity of at least 98 % for reliable corrosion control. The solid form is supplied in polyethylene bags or plastic drums, which matches standard bulk‑chemical logistics. The chemical is stable at ambient temperature and resists hydrolysis even at high pH, making it suitable for continuous cooling‑water circuits.

Typical end‑users include power‑generation plants, chemical factories, metallurgical operations and fertilizer producers that require low‑pressure boiler treatment. The recommended dosage is 1‑10 mg L⁻¹ for scale inhibition, 10‑50 mg L⁻¹ for corrosion protection and 1 000‑2 000 mg L⁻¹ for detergent action in textile processing. Packaging is offered in 25 kg bags or 200 kg drums; exact MOQ and lead times are not disclosed and should be confirmed directly with the supplier.

Zaozhuang Xintai Water Treatment Technology Co., Ltd is located in Xiwangzhuang Town, Shizhong District, Zaozhuang, Shandong, China (postcode 277100). The company is listed as an imported supplier with a harbour‑level trust tier, although its response rate on the platform is currently zero, indicating that enquiries may need follow‑up through alternative contact channels.

The firm advertises HEDP for use in circulating cooling‑water systems, oil‑field operations and low‑pressure boilers, as well as in textile detergent formulations and dye‑fixing processes. Packaging is offered in standard bulk containers such as plastic drums, but the listing does not specify minimum order quantities, lead times or payment terms, so buyers should request those details directly.
