Import Dtpmpa — Buy in Bulk from Supplier in China

DTPMPA is a phosphonate-based sequestrant sold as a brown liquid with an active acid content of 48.0 to 52.0 percent, measured by titration. Its 1% aqueous solution has a pH no higher than 2.0 at 25°C, and its specific gravity ranges from 1.350 to 1.450 at 20/20°C. Chloride content is tightly controlled between 15.0 and 17.0 percent, ensuring compatibility with sensitive water treatment systems. The sequestrant value for calcium carbonate is a minimum of 450 mg/g, indicating strong chelating capacity for divalent metal ions.

This product is formulated for industrial water treatment applications where iron and scale control are critical. The iron content is capped at 35 ppm, a standard threshold for high-purity phosphonates used in boiler and cooling systems. Typical industry-grade DTPMPA contains 45 to 55 percent active acid, with chloride levels below 20 percent; this listing falls within those norms. The brown coloration is normal and results from trace organic impurities inherent in the synthesis process, not degradation.

Buyers in power generation, textile dyeing, and oilfield operations source this material for its ability to inhibit calcium phosphate and iron oxide scaling. It is commonly used in conjunction with polymeric dispersants in closed-loop cooling circuits. Packaging is in 200 kg HDPE drums or IBC totes. Minimum order quantities are not specified; confirm with the supplier. Lead times and Incoterms are not stated and must be verified directly.

Jiaozuo Mengxin Special Steel Co., Ltd is located in Zhaohe Town, Mengzhou, Henan Province, China. The supplier is classified as an imported tier with harbor trust verification, indicating physical presence and export readiness. The listing does not state years in operation, production volume, or client names. Response rate and average response time are not available, suggesting limited digital engagement but not necessarily operational incapacity.

The company's focus appears to be on specialty chemical production for industrial markets, with DTPMPA as one of its listed offerings. No certifications such as ISO, RoHS, or NSF are referenced. There is no mention of R&D capacity, third-party testing, or in-house quality control protocols. Buyers should treat this as a direct manufacturer of bulk liquid phosphonates without verified quality systems unless confirmed independently.
