Sodium Of Polyaspartic Acid (PASP)
CAS No. 181828-06-8,35608-40-6Molecular weight: 1000-5000
Molecular formula: C4H6NO3(C4H5NO3)C4H6NO4
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
agents, avoiding water system eutrophication and second pollution..

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
