Import Diethylene Triamine Penta — Buy in Bulk from Supplier in China

Diethylene triamine penta, also known as DTPMPA with CAS No 15827-60-8, is a phosphonic acid compound used primarily as a scale and corrosion inhibitor in industrial water systems. The product is supplied as a brown transparent liquid with an active acid content of 48.0% to 52.0% and a chloride content of 12% to 17%. Its molecular formula is C9H28O15N3P5 and molecular weight is 573.2 g/mol. The density at 20°C ranges from 1.35 to 1.45 g/cm³, and the pH of a 1% solution is approximately 2.0. Iron content is limited to 35 ppm maximum.

This compound exhibits strong thermal stability and performs effectively in alkaline environments above 210°C, outperforming other organophosphines under such conditions. It inhibits carbonate, sulfate, and phosphate scale formation without requiring additional pH adjustment, making it suitable for circulating cooling systems and boiler water applications. The product is also used as a peroxide stabilizer, chelating agent in dyeing, pigment dispersant, and concrete modifier. It does not require dispersants to prevent sedimentation when used alone, a feature valued in high-mineral-content water systems.

Buyers include industrial water treatment facilities, oilfield operators, and manufacturers in papermaking, electroplating, and fertilizer production. The product is typically packed in 250kg plastic drums or IBC containers as required. Storage should be in a cool, dry, shaded location with a shelf life of up to ten months. Buyers must confirm compatibility with existing chemical programs and verify handling procedures due to its acidic nature. No certifications are listed, so buyers should request test reports for batch-specific performance.

Shandong Taihe Water Treatment Co., Ltd. is a manufacturer based in Zaozhuang, Shandong Province, China, with its registered address in Hongcun, Xiwangzhuang Town. The company is listed as an imported supplier with harbor-level trust tiering, indicating it has passed basic verification for export documentation and facility location. There is no public data on years in operation, production volume, or client list. The listing confirms direct manufacturing capability through the inclusion of detailed chemical specifications and packaging methods typical of a producer, not a trader.

The supplier has not provided response rate or average response time, suggesting limited active communication on the platform. No certifications such as ISO, SGS, or REACH are claimed. The absence of these claims does not imply non-compliance but requires buyers to request batch-specific test reports. The facility's location in Zaozhuang places it within a known regional cluster for water treatment chemicals, supporting logistical reliability for bulk exports from Qingdao or Shanghai ports.
