Application & Funtion

In chemical industry, it can be used as raw material for synthetic resins, a large number of environmental protection materials for synthesis of polyaspartic acid, as well as nutritional additives for cosmetics. Aspartic acid can be used as a nutritional supplement to add to various refreshing beverages. It can be used as antidote, liver function promoter and fatigue eliminator in medicine. It can also be used as biochemical reagent, culture agent and organic synthesis intermediates, as well as as as the raw material of new sweetener aspartame (amino acid sweetener suitable for diabetes mellitus), which has good market prospects.
 

Poly-L-aspartic acid is a water soluble polymer, 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. it  is an alternative of phosphor-containing Water Treatment Chemicals, avoiding water system eutrophication and second pollution.
