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

Shandong Taihe Water Treatment Co., Ltd. supplies Amino Trimethylene Phosphonic Acid (ATMP) in both liquid and solid crystalline forms from Zaozhuang, Shandong Province, China. The liquid grade carries 48-52% active acid with a maximum chloride content of 2.0% or 1.0% depending on variant, pH not exceeding 2.0 in a 1% solution, and density of at least 1.33 g/cm3 at 20 degrees Celsius. The solid crystalline grade offers 95% minimum active acid, identical chloride and iron limits, and is specifically recommended for cold climates and winter applications where liquid freezing is a concern.

The solid ATMP is highly deliquescent, absorbing atmospheric moisture to form a concentrated solution, which necessitates sealed packaging with inner polyethylene liner and outer woven polypropylene. Both grades employ the same phosphonate functionality, N(CH2PO3H2)3, molecular weight 299.05, CAS 6419-19-8, to deliver chelation, threshold inhibition and lattice distortion against calcium carbonate and other alkaline earth scales. The chemical stability against hydrolysis exceeds that of polyphosphates, maintaining performance across pH 7-12 and temperatures up to 100 degrees Celsius in typical cooling circuits.

Primary markets include thermal power generation, petroleum refining, oilfield water injection and reverse osmosis pre-treatment, with dosage ranges of 1-20 mg/L for scale inhibition and 20-60 mg/L for corrosion protection when combined with zinc or molybdate. Textile dyeing and metal surface treatment represent secondary applications where the high-purity solid grade is preferred. Buyers should confirm with Shandong Taihe whether the liquid is supplied in 250 kg drums or IBCs, and whether the solid is packed in 25 kg PE-lined woven bags as standard, since project-scale requirements may warrant customised packaging solutions.

Shandong Taihe Water Treatment Co., Ltd. is located at Hongcun, Xiwangzhuang Town, Shizhong District, Zaozhuang 277100, Shandong, China. The supplier carries an imported tier and harbour trust designation, indicating platform verification of business credentials. The response rate is recorded at 0.00% with zero average response hours, which suggests buyers should proactively initiate contact and allow adequate time for quotation and technical discussion.
