Introduction
ATMP Na5 scale inhibitor (sodium aminotrimethylene phosphonate pentasodium salt) is essential for industrial water treatment, oilfield chemicals, and heavy-duty cleaning formulations. This pentasodium salt offers superior solubility and lower corrosivity compared to ATMP acid form, making it the preferred choice for formulation engineers and international procurement specialists.
As a China ATMP Na5 manufacturer with ISO 9001:2015 certification (CN19/HOO-2025-001), HOOCHEMTEC supplies high-purity ATMP·Na5 to 28 countries, serving 350+ water treatment formulators globally. Our products help you build scale-free systems with simplified logistics for high-alkalinity industrial applications.
What is Sodium Aminotrimethylene Phosphonate (ATMP Na5)
ATMP Na5 is the pentasodium salt of Amino Trimethylene Phosphonic Acid (phosphonate scale inhibitor family). Chemical names include Pentasodium Aminotrimethylene Phosphonate and the sodium salt of ATMP.
Key Identifiers:
Molecular Formula: C₃H₇NO₉P₃Na₅
CAS Numbers: 2235-43-0 (Na5 salt), 20592-85-2 (ATMP acid)
ATMP acid vs salts: While ATMP acid (CAS 20592-85-2) offers maximum activity, ATMP Na5 provides full neutralization (pH 10-11), better stability, and easier handling in alkaline formulations.
Physical Properties:
Appearance: Colorless to pale yellow transparent liquid
pH (1% solution): 10.0-11.0
Density (20°C): 1.38-1.48 g/cm³
ATMP Na5 Scale Inhibition Performance & Mechanism
ATMP Na5 scale inhibitor operates via multi-stage protection:
- Threshold Effect: Prevents CaCO₃/CaSO₄ precipitation at dosages as low as 2-5 ppm
- Lattice Distortion: Warps crystal structures, preventing scale adhesion
- Chelation: Forms stable complexes with Ca²⁺, Mg²⁺, Fe³⁺ ions
Synergy: Combined with zinc salts/polycarboxylates, performance increases 200-300%. Thermal stability maintains >90% activity at 120°C, ideal for high-pressure boilers and oilfield reinjection.
Real Case: Saudi Aramco facility reduced scale by 42%, saving $185K annually in downtime.
ATMP Na5 Applications in Water Treatment, Oilfield and Cleaning
1. Industrial Water Treatment
- Circulating cooling water: Prevents scale in heat exchangers
- Boiler water: High-temperature scale control
- RO membrane antiscalant: Extends membrane life 25-35%
2. Oil & Gas
- Produced water treatment: Controls barium/strontium sulfate
- Reinjection systems: Maintains injectivity under HP/HT conditions
3. Industrial Cleaning
- Heavy-duty degreasers: Sequestering agent boosting surfactant efficiency
- Textile/peroxide stabilizer: Prevents metal-catalyzed decomposition

FAQs
What is the lead time and shelf life for a standard 20ft container order?
Answer: For a standard order, the production and export processing lead time at HOOCHEMTEC is typically 7–14 days.
What are the standard packaging and Incoterms for international ATMP·Na5 shipments?
To optimize logistics costs, ATMP·Na5 is most commonly shipped in 250kg plastic drums (80 drums per 20’FCL) or 1250kg IBC tanks. For high-volume buyers, ISO tanks or tank trucks are available. We typically offer FOB (Free on Board) or CIF (Cost, Insurance, and Freight) terms. Given the liquid nature of the product, we ensure all packaging is UN-rated for sea freight to prevent leakage and ensure smooth customs clearance in your destination port.
How do I verify the quality of ATMP·5Na from a Chinese manufacturer?
Quality verification should be based on a comprehensive Certificate of Analysis (COA). As a professional procurement specialist, you should focus on three “Critical-to-Quality” (CTQ) indicators: Active Content (typically 38% min), Total Phosphorus, and Iron (Fe) content. High iron levels can cause product discoloration and interfere with chelation efficiency. At HOOCHEMTEC, we provide batch-specific COAs and support third-party inspections (SGS/BV) to ensure 100% compliance with your technical data sheets.
