Polyaspartic Acid (PASP) is a soluble polymer. PASP is a new generation of green water treatment agent, with properties of non-phosphor, non-nitrogen, non-pollution and fully biodegradation. PASP has strong chelating effect to calcium ion, has double effects of corrosion inhibitor and antiscale. PASP has good antiscale effects on calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate, etc.. Its antiscale rate for calcium carbonate is 100%. Moreover, PASP possess dispersion and corrosion inhibitor properties.

1. PASP can be used as antiscale and corrosion inhibitor fields of industrial circulating cool water system, boiler water, inverse 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.

2. Due to its green and non-pollution to environment, PASP can be used as accessory ingredients in daily and fine chemicals.

3. 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.
