 Polyaspartic Acid Sodium Salt (PASP)

CAS No.: 181828-06-8, 35608-40-6
Molecular weight: 1000-5000
Molecular Formula: C4H5NO3M(C4H4NO3M)m(C4H4NO3M)nC4H4NO3M2

PASP 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 ful 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, can resist the corrosion of metal equipment.
PASP is an alternative of phosphor-containing water treatment chemicals, avoiding water eutrophication and second pollution.

PASP can be used as scale and corrosion inhibitor in industrial circulating cooling water, boiler water, reverse osmosis water, oilfield water and desalination plant. The effects will be even better than ordinary organophosphines when used in situation of high hardness, high alkalinity, high pH value and high cycles of concentration. When it is compounded with PBTCA, the synergism is obvious.
Due to the environmental protection performance, PASP can be used as daily chemical additives and fine chemicals.
PASP can be used in agricultural industry as nutrient absorption intensifier to improve the production of vegetable-responsive, melons, fruits, flowers, etc. When it is used together with pesticide, its effects will be better.
