Global demand for HEDP-based water treatment chemicals grew 12.7% CAGR (2020-2023), with zinc-stabilized formulations capturing 38% market share. Zinc HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) demonstrates 40% greater scale inhibition efficiency than traditional polyphosphates, reducing boiler maintenance costs by $18-22 per metric ton of treated water.
Third-party testing confirms Zn HEDP maintains 94% chemical stability at 250°C vs. 78% for conventional amino trimethylene phosphonic acid (ATMP). Key performance metrics:
Parameter | Zn HEDP | ATMP | PBTC |
---|---|---|---|
Calcium Chelation (mg/g) | 620 | 450 | 580 |
pH Tolerance Range | 2-12 | 3-9 | 2-11 |
Thermal Decomposition Point (°C) | 255 | 190 | 230 |
Price benchmarking across 17 manufacturers reveals Zn HEDP trades at $1,450-1,900/ton FOB China, with polydisperse grades commanding 22% premium. European producers average $2,300-2,800/ton for equivalent purity (≥98.5%).

A: Zn HEDP is a corrosion and scale inhibitor commonly used in industrial water treatment systems. It combines the chelating properties of HEDP with zinc for enhanced metal ion stabilization. This formulation is effective in preventing boiler and cooling system deposits.
A: HEDP pricing depends on raw material costs, production scale, and regional market demand. Environmental regulations and global supply chain dynamics also impact pricing. Bulk purchases typically qualify for discounted rates.
A: Polydisperse HEDP contains molecules with varied molecular weights, offering broader application compatibility. This diversity improves performance in complex water chemistry environments. It maintains the same scale inhibition properties as monodisperse HEDP but with enhanced adaptability.
A: HEDP effectively binds calcium and magnesium ions to prevent scale formation at low concentrations. It remains stable in high-temperature and high-pressure environments. Its biodegradability and low toxicity make it environmentally preferable to many alternatives.
A: Yes, Zn HEDP often outperforms phosphate-based treatments in corrosion inhibition while reducing environmental impact. It works synergistically with other additives for multi-functional protection. Regulatory compliance and system compatibility should be verified before substitution.
