Structural Formula:
Properties:
Sodium of Polyaspartic Acid is a kind of artificial biomimetic synthesis of water-soluble polymer material.
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.
Sodium of Polyaspartic Acid is an alternative to phosphor-containing Water Treatment Chemicals, avoiding water system eutrophication and second pollution.

Usage:
PASP can be used as a 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 situations 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 the environment, PASP can be used as accessory ingredients in daily and fine chemicals.
Sodium of Polyaspartic Acid can be used in agriculture as a nutrient absorption intensifier to improve vegetables, melons and fruit, and flowers. When used together with pesticides, its effects will be improved.
Package and Storage:
200L plastic drum,IBC(1000L),customers’ requirement. Storage for ten months in shady room and dry place.
Safety Protection:
