HEDP is an abbreviation for 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, Etidronic Acid.ATMP is an abbreviation for Amino Tri(Methylene Phosphonic Acid), Nitrilotrimethylphosphonic Acid(NTP)HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, 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.ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. ATMPcan decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.HEDP had better synergistic effect with other polymers or chemicals comparing with ATMP.
They belong to phophonates, can be used as anti-scalent and corrision inhabitor in circulating cooling system, performances are quite good.
HEDP (High Explosive Dual Purpose), High Explosive, Star Parachute White, Star Cluster White, Ground Marker- Red - Green - or Yellow, Practice, Tactical CS Gas, Shotgun.
HPAA (2-Hydroxyphosphonocarboxylic Acid) ( HPAA, HPMA, HEDP) CAS No 23783-26-8 Properties: HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. Specification: Appearance: Dark umber transparent viscous liquid Solid content : 47.0-50.0% Phosphorous acid(as PO33-): 4.0 % max Density (20centigrade): 1.30 g/cm3 min pH(1% solution) : 1.0-3.0 Usage: HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.

During the past two decades, new generations of antiscalants (AS) have emerged commercially, in which the active ingredients are mostly proprietary mixtures of various molecular weight polycarboxylates and polyacrylates. Optimal molecular weights have been reported in the range of 1,000- 3,500. Other polyelectrolytes including polyphosphonates and polyphosphates have also been applied successfully with certain types of feed waters. http://www.polysep.ucla.edu/research%20advances/desalination/aniscalants.htm Antiscalant chemicals generally known as reverse osmosis membrane treatment chemicals are prepared with SHMP (Sodium Hexa Meta Potassium), HEDP and dilution of water as per required. The quality of antiscalant chemicals depends on its concentration and the density of polymer used to prepare antiscalant chemicals. If you are looking for antiscalant chemicals of effective and efficient quality in India then you may consult Aqua Innovative Solutions - One of the leading water treatment chemicals manufacturer in India. Aqua Innovative Solutions are the renowned manufacturers of antiscalant chemicals which are used in various industries like, pharmaceuticals, chemical industries, distilleries, plastic industries and other.
