Poly-L-aspartic acid application:

1. Poly-L-aspartic acid is widely used as a scale inhibitor and corrosion inhibitor in water treatment fields such as industrial circulating water, boiler water, reverse osmosis water, oilfield water, and seawater desalination. It performs well in high hardness, high alkalinity, high pH, ​​and high concentration multiples systems. The scale inhibition effect of Poly-L-aspartic acid is better than that of commonly used phosphine-containing scale inhibitors.
2. Due to its green and environmentally friendly characteristics, Poly-L-aspartic acid can be used as a new type of daily chemical additive and various non-toxic and pollution-free special fine chemicals.

Poly-L-aspartic acid Packaging and Shipping 

Plastic drum or ton bag, with 25kg or 250kg per drum and 1000kg or 1250kg per ton bag, which can also be determined according to user needs.

Poly-L-aspartic acid Storage

It should be stored in a cool place indoors for twelve months
