(sodium hedp)
Sodium hydroxyethylidene diphosphonate (HEDP) and its derivatives, including polyaspartic acid sodium salt, have emerged as critical components in industrial water treatment. These compounds exhibit exceptional scale inhibition properties, reducing calcium carbonate deposition by up to 98% in cooling tower systems. Unlike conventional phosphonates, sodium HEDP maintains stability at temperatures exceeding 100°C while demonstrating superior biodegradability (78% degradation within 28 days).
The global market for sodium of polyaspartic acid products is projected to grow at 6.2% CAGR through 2030, driven by:

With sodium hedp
demonstrating 40% longer service life than aminotrimethylene phosphonic acid (ATMP) in field tests, its adoption continues to accelerate. The compound's unique molecular structure enables simultaneous scale inhibition and corrosion protection, particularly when combined with polyaspartic acid sodium salt synergists. As industries face stricter environmental regulations, sodium HEDP-based solutions offer both compliance advantages and operational cost benefits.
