Import Amino Trimethylene Phosphonic Acid (Atmp) — Buy in Bulk from Supplier in China

ATMP (CAS 6419-19-8, molecular weight 299.05, formula N(CH2PO3H2)3C) is an organophosphonic acid scale inhibitor and chelating agent supplied by Zaozhuang Dongtao Chemical Technology Co., Ltd. from Shandong Province, China. The liquid grades offered contain active content of 50.0% minimum, with density at 20 degrees Celsius of at least 1.28 g/cm3 for the standard liquid and 1.30 g/cm3 for the higher grade. A solid crystalline powder variant with 92.0% minimum active content is also available for cold-climate applications where easy moisture absorption and freeze-thaw stability matter.

This phosphonate functions through multiple mechanisms: chelation of calcium and magnesium ions, low-threshold inhibition of crystal growth, and lattice distortion that prevents carbonate scale nucleation. Its hydrolytic stability exceeds that of many phosphonates, maintaining performance across broad pH and temperature ranges in circulating cooling systems, thermal power plants, oil refinery loops, and oilfield waterflood operations. The acid is typically formulated with polycarboxylic acids and their salts to build all-organic alkaline treatment programs, with dosage ranging from 5-20 mg/L for scale control and 20-80 mg/L for corrosion inhibition.

Industrial buyers include water treatment chemical formulators, power station operators, petroleum refiners, and textile dyehouses requiring metal ion sequestration. The solid form suits woven and dyeing applications and metal surface treatment where higher purity is essential. Packaging is 30 kg or 250 kg plastic drums for liquid, and 25 kg inner PE liner with outer plastic woven bag for solid. Buyers should confirm winter storage requirements and compatibility with existing formulation chemistries before specifying grade.

Zaozhuang Dongtao Chemical Technology Co., Ltd. is located in Shizhong District, Zaozhuang, Shandong Province, China (postal code 277122). The company operates as an imported-tier supplier within the harbor trust tier, indicating basic marketplace verification without additional third-party assurance layers. Its response rate stands at 0.00% with zero average response hours recorded, which buyers should note when planning procurement timelines and communication expectations.

The supplier listing focuses on ATMP as a core water treatment chemical, presenting technical specifications across three product grades rather than company history or manufacturing scale. No information is provided about production capacity, year of establishment, number of employees, annual revenue, or specific client references. Buyers should verify factory audit status, ISO certification, and production batch testing capabilities directly with the supplier before committing to volume orders, as these standard due diligence items are absent from the available profile.
