HEDP 98%

HEDP 98% – (CAS 2809-21-4) Supplier in South Africa

HEDP 98%, also known as 1-Hydroxyethylidene-1,1-Diphosphonic Acid, Hydroxyethylidene Diphosphonic Acid, or Etidronic Acid, is a highly effective organophosphonic acid widely used as a scale inhibitor and corrosion inhibitor in water treatment systems. This powerful chelating agent is valued for its excellent ability to control scale formation, metal ion deposition, and corrosion in industrial processes. HEDP is commonly used in water treatment formulations due to its stability, high purity, and strong performance under high temperature and alkaline conditions.

Physical Details and Properties:

HEDP 98% (chemical formula C₂H₈O₇P₂) is typically supplied as a white crystalline powder or solid with high purity. It is highly soluble in water and demonstrates excellent chelating, scale inhibition, and corrosion control properties. HEDP has strong stability under harsh conditions and performs effectively even in high pH environments and elevated temperatures. It is compatible with many other water treatment chemicals such as polyacrylic acid (PAA), ATMP (Aminotris(methylene phosphonic acid)), and DTPMP (Diethylenetriamine penta(methylene phosphonic acid)), making it a valuable ingredient in industrial water treatment formulations.

Industrial Applications:

HEDP 98% is widely used in industrial water treatment systems, including cooling towers, boilers, desalination plants, and circulating water systems, where it helps prevent scale formation and corrosion caused by metal ions such as calcium, magnesium, and iron. It is also used in oilfield water treatment, detergents, textile processing, and metal surface treatment.

Additionally, HEDP is used in cleaning formulations, electroplating chemicals, and scale prevention products, helping maintain equipment efficiency and extending the lifespan of industrial systems. Its ability to form stable complexes with metal ions makes it particularly useful in preventing mineral deposits and improving water quality.

Safety Information:

HEDP 98% should be handled with proper industrial safety precautions. Direct contact with concentrated material may cause irritation to the skin or eyes, so appropriate protective equipment such as gloves and eye protection should be used when handling. The product should be stored in a cool, dry, and well-ventilated area in tightly sealed containers. Safety Data Sheets (SDS) should always be consulted for detailed handling, storage, and transportation guidelines.
