Properties:
Hydrolyzed polymaleic anhydride (hpma) is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330¬. Hpma has obvious threshold effect under high temperature (350¬) and high ph(8.3)level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300¬ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, hpma is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, hpma has good corrosion inhibition effect when used together with zinc salt. Hpma can also used as additives for cement.

Structural Formula:
Properties:
PASP is a water soluble polymer. It is a green water treatment agent, with properties of non-phosphor, non-nitrogen, non-pollution and fully biodegradation. PASP has good scale inhibition on calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate, etc.. Its scale inhibition rate for calcium carbonate is 100%. Moreover, PASP has dispersion and corrosion inhibition properties to metal equipment.
PASP is an alternative of phosphor-containing Water Treatment Chemicals, avoiding water system eutrophication and second pollution.

Appearance Amber transparent liquid
Solid content % 40.0 min
Density (20íµ)g/cm3 1.2 min
pH(1% water solution) 9.0-11.0
Usage:
PASP can be used as scale and corrosion inhibitor in industrial circulating cool water system, boiler water, reverse osmosis, oilfield water and desalination plant. The effects will be even better than ordinary organophosphines when used in situation of high hardness, high alkaline, high pH value and high concentration index. When built with PBTCA, the synergism is obvious.
Due to its green and non-pollution to environment, PASP can be used as accessory ingredients in daily and fine chemicals.
PASP can be used in agricultural as nutrient absorption intensifier to improve the production of vegetable, melon and fruit, and flowers. When used together with pesticide, its effects will be improved.
Package and Storage:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
Safety Protection:
Alkaline, Avoid contact with eye and skin, once contacted, flush with water.

Molecular formula: c2h8o7p2, molecular weight: 206
Structural formula:
Properties:
This product is an organophosphoric acid corrosion inhibitor, it can chelate with fe, cu, and zn ions to form stable chelating compounds, thus it can dissolve the oxidized materials on these metalsf+ surfaces. Hedp shows excellent antiscale corrosion inhibition effects under temperature 250f¬. It has good stability under high ph value, is hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its properties of acid/alkali and chlorine oxidation resistance are better than that of other organophosphoric acids (salt). Hedp can react with metal ions in water system to form hexa-element chelating complex, especially with calcium ion to form capsule polymer chelating complex. Therefore, this product has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effective performance.
