Copper EDTA

Description

1. Product Overview
Copper EDTA (Ethylenediaminetetraacetic acid, copper disodium complex) is a high-purity, chelated micronutrient engineered for precise delivery of copper ions in demanding industrial and agricultural formulations. Its primary industrial use is as a stable, water-soluble copper source in crop nutrition, hydroponics, and industrial chemical catalysis. The key value proposition is exceptional bioavailability and stability across a broad pH range (2–10), eliminating copper precipitation and ensuring predictable performance. Strategically, it is critical for growers and formulators seeking to maximize yield quality while minimizing heavy metal toxicity risks—an imperative as global regulations tighten on metal runoff and soil health.

2. Key Specifications & Technical Characteristics

• Chemical composition: CuC₁₀H₁₂N₂O₈Na₂ · xH₂O (Copper disodium EDTA)

• Purity level / Grade: ≥ 99% chelated copper content; 14.5–15.0% Cu by weight (industrial/agricultural grade)

• Physical characteristics:

  • Form: Fine, free-flowing crystalline powder

  • Color: Light blue to turquoise

  • Particle size: 100% passes through 40 mesh (standard); custom milling available

  • Bulk density: 650–750 kg/m³

  • pH (1% solution): 5.0–7.0

  • Water solubility: 450 g/L at 20°C

• Packaging options: 25 kg multi-layer kraft + PE bags; 500 kg and 1,000 kg bulk FIBCs; custom palletization for ISO containers

• Shelf life: 36 months in original unopened packaging, stored below 40°C in dry conditions (no caking guarantee)

3. Core Industrial Applications

• Precision agriculture & fertigation: Corrects copper deficiency in cereals, citrus, vines, and tree nuts. Performs better than copper sulfate due to zero phytotoxicity risk and full tank-mix compatibility with phosphates and sulfates.

• Hydroponics & soilless media: Provides steady Cu²⁺ availability without pH adjustment, preventing root burn and tip dieback—critical for high-value greenhouse vegetables and cannabis.

• Industrial catalysts & electroplating: Used as a stable copper source in electroless plating and polymer synthesis. Outperforms inorganic copper salts by eliminating sludge formation and extending bath life by 40–60%.

• Wood preservative formulations: Enhances copper penetration in treated lumber, reducing leach rates by >70% compared to traditional oxides.

Efficiency gain: Users typically reduce total copper application rates by 25–35% while achieving superior crop response or catalytic activity.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production; every batch tested for residual free EDTA (<0.5%), heavy metals (Pb, Cd, As < 5 ppm), and dissolution clarity.

• Supply reliability: Dual-sourced raw materials + 6-month rolling safety stock; average lead time 15 days ex-warehouse (global hubs: Rotterdam, Singapore, Houston, Shanghai).

• Logistics capability: Full IMO/DG compliance; temperature-controlled container options for tropical transit.

• Price competitiveness: Direct-from-manufacturer pricing with volume tier discounts—no hidden broker fees.
