In the USA, UAE, Iran Iraq, Kuwait, Saudi Arabia and other oil producing areas, several hundred chemical compounds are used in hydraulic fracturing also called fracking, fracing or frac. In some areas like UK only 'Non-Hazardous' chemicals are permitted for fracturing fluids by the Environment Agency. All chemicals have to be declared publicly and increasingly, food additive based chemicals are available to allow fracking to take place safely.
Mubychem is an internationally preferred source for Stimulation Chemicals and Hydraulic Fracturing Chemicals. We serve various oil and shale gas producing countries like USA UAE, Kuwait, Iran, Iraq, Saudi Arabia, UK, Europe India etc. We are never too far from your well-site with multiple 24/7 company owned or rented warehouses in the India, USA and across the globe. With customers in several countries, we sell almost all the fracturing chemicals.

Applications:
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or Hydroxy Ethylidene Diphosphonic Acid or HEDP is mainly used as a scale and corrosion inhibitor, chelating (sequestrating), deflocculating agent in cooling and boiler water treatment, textile dying detergent etc.
In light woven industry, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP is used together with polycarboxylic acid. HEDP Phosphonate is also used in Fracturing Chemicals.
Packing:
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP is generally packed in 250kg plastic drums or in bulk totes. It can be packed as per buyers requirement.
Properties:
Hydroxy Ethylidene Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP Phosphonate is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals’ surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250. HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or Hydroxy Ethylidene Diphosphonic Acid or HEDP Phosphonate has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
