Understanding Sodium HEDP: A High-Performance Solution

Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid Sodium Salt) has emerged as a superior scale and corrosion inhibitor across industries. With a global market CAGR of 5.8% (2023-2030), this polyaspartic acid sodium salt derivative demonstrates 92% scale inhibition efficiency at concentrations as low as 8-15 ppm, outperforming traditional phosphonates. Its unique molecular structure enables stable performance in extreme conditions (pH 2-12, up to 250°C).

Technical Superiority in Water Treatment

Third-party testing reveals sodium HEDP's exceptional characteristics:

Calcium carbonate inhibition: 98% at 10 mg/L dosage
Corrosion rate reduction: 0.025 mm/year on carbon steel
Thermal decomposition point: 330°C (vs. 210°C for ATMP)

The sodium of polyaspartic acid formulation shows 40% better biodegradability than conventional scale inhibitors, meeting EPA Safer Choice criteria.

FAQS on sodium hedp

Q: What is sodium HEDP commonly used for?

A: Sodium HEDP is primarily used as a scale and corrosion inhibitor in industrial water treatment, boilers, and cooling systems. It effectively prevents mineral deposits and extends equipment lifespan.

Q: How does polyaspartic acid sodium salt differ from sodium HEDP?

A: Polyaspartic acid sodium salt is a biodegradable, eco-friendly alternative for scale inhibition, while sodium HEDP contains phosphorus and is non-biodegradable. Both are used in water treatment but cater to different environmental priorities.

Q: Can sodium HEDP and polyaspartic acid sodium salt be used together?

A: Yes, they can be combined in water treatment formulations to enhance scale inhibition and corrosion resistance. However, compatibility testing is recommended to avoid chemical interactions.

Q: What industries rely on sodium of polyaspartic acid?

A: The sodium salt of polyaspartic acid is widely used in agriculture (as a fertilizer additive), detergents, and municipal water treatment due to its biodegradability and non-toxic properties.

Q: Is sodium HEDP environmentally safe?

A: Sodium HEDP has low toxicity but is not biodegradable, requiring careful disposal to avoid environmental accumulation. Regulations may restrict its use in eco-sensitive applications compared to polyaspartic acid sodium salt.
