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

Amino Trimethylene Phosphonic Acid (ATMP) from Zao Zhuang Xin Tai Water Treatment Technology Co., Ltd. is an phosphonate-based scale inhibitor and chelating agent supplied from Shandong Province, China. The liquid grade presents as a colorless or light yellow transparent liquid with active acid content of 48.0-52.0 percent, while the solid grade is a white crystal powder with minimum 95 percent active acid. The supplier offers both forms to suit different climatic and handling conditions, with the solid grade particularly indicated for winter and freezing districts due to its reduced deliquescence risk. Density at 20 degrees Celsius is minimum 1.33 grams per cubic centimeter for the liquid, and pH of 1 percent solution is maximum 2.0 for both grades.

The molecular backbone of ATMP combines a nitrogen atom with three methylene phosphonic acid groups, yielding strong chelation capacity for calcium, magnesium and other divalent metal ions. This structure provides low threshold inhibition, meaning effective scale prevention at concentrations far below stoichiometric levels, plus lattice distortion that interferes with regular crystal growth on heat exchange surfaces. Chloride content is controlled to 2.0 percent maximum for the liquid grade (or 1.0 percent on higher purity variants) and 1.0 percent maximum for the solid. Iron contamination as Fe3+ is limited to 20 parts per million for both grades. Color is specified as maximum 40 APHA Hazen units for the liquid, indicating consistent manufacturing control.

Primary applications include industrial circulating cool water systems, thermal power plant water circuits, oilfield water pipelines and refinery cooling operations where calcium carbonate scale prevention is critical. ATMP also serves as a chelating agent in textile dyeing and as a metal surface treatment agent. The recommended dosage as a scale inhibitor is 1-20 milligrams per litre, rising to 20-60 milligrams per litre when deployed primarily for corrosion inhibition. Standard packaging comprises 250 kilogram net plastic drums for liquid product, with IBC drums available on request; solid grade ships in 25 kilogram inner liner polyethylene bags with outer plastic woven bags, though client-specified alternatives can be arranged.

Zao Zhuang Xin Tai Water Treatment Technology Co., Ltd. operates from Zhongtai Industry Zone in Xiwangzhuang Village, Shizhong District, Zaozhuang, Shandong Province, with postal address 277100. The company is classified as an imported-tier supplier within a harbor trust tier, indicating it has passed baseline verification for cross-border trade eligibility. Its physical location in Shandong places it within one of China's denser clusters of chemical manufacturing and water treatment technology development. The listing does not state year of establishment, production capacity, number of employees, revenue figures or specific client references.

Response rate is recorded at 0.00 percent with zero average response hours, which buyers should interpret as no guaranteed response performance rather than active unreliability. The supplier profile offers no ISO, SGS or other third-party certification details, and no export license numbers or customs registration data is visible. The product range is focused narrowly on ATMP in liquid and solid grades, suggesting specialisation in phosphonate chemistry rather than broad water treatment portfolio. Buyers are advised to verify current production capacity, quality management system status, and export documentation capabilities directly with the supplier before committing to volume orders.
