Polyaspartic acid (PASP), biodegradable and environment friendly, is a kind of green chemicals of demand increasing globally. The synthesis and application of PASP is popular in many countries because the problem of environment has been paid more and more attention. The field of PASP application is not same with different molecular weight range.

APPLICATION


●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.

●As a metal corrosion inhibitor, PASP has good corrosion inhibition ability with ph＞10 and it also has good corrosion inhibition ability with low concentration for sea water. When built with organophosphor, sodium tungstate, quatemary ammonium salt, zinc salt, molybdate, oxidized starch, and so on, the synergism is obvious.

●As a nutrient absorption enhancer, PASP can be used in agriculture. When PASP is applied to fertilizer, it can enhance the availability of N, P, and K resulting in increase yields because of its high capacity for chelating metal ions.

●As a new polymer, PASP can be reacted with crosslinker  into superabsorbent agent. This product with properties of non-pollution and fully biodegradation can be used for hygiene products.
