Polyaspartic acid sodium is a water-soluble polymer. It is a green water treatment agent, with properties of non-phosphor, non-nitrogen, non-pollution and fully biodegradation. Polyaspartic acid sodium has good scale inhibition on calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate, etc.. Its scale inhibition rate for calcium carbonate is 100%.
Moreover, polyaspartic acid sodium 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.

Polyaspartic acid sodium 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 a situation of high hardness, high alkaline, high pH value, and high concentration index. When built with PBTC, the synergism is obvious.
Due to its green and non-pollution to the environment, PASP chemicals can be used as accessory ingredients in daily and fine chemicals.
Polyaspartic acid sodium 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.
