Introduction of the Product
Performance
Polyaspartic acid is a kind of artificial synthetic biomimetic water soluble high molecular polymer material, having the
characteristics of no phosphorus, non-toxic, pollution-free and complete biodegradable, and is a kind of internationally
recognized “Green Chemicals”. Having the structure characteristics of peptide bond and active group such as carboxyl
group, polyaspartic acid has strong effects such as chelate, dispersion, and adsorption, etc. and also has a good
compatibility. It is widely used as the fertilizer synergist, and the corrosion inhibitors in the water treatment fields such
as industrial cooling circulating water, reverse osmosis water, back injection water in oil field, metal cutting fluid, and
boiler and steam pipeline; It can also be used as dispersant in papermaking, printing and dyeing and washing industry
and the daily chemical field.

Application
1. As the special agricultural fertilizer synergist, polyaspartic acid is the raw material of the polypeptide urea,
polypeptide compound fertilizer, and controlled release fertilizer. It can promote the absorption of nutrients
for the grain, vegetables, melons and fruits, flowers and the other crops. At the same time, it can improve the
effect together with the pesticide. The domestic and foreign research and application results indicate that
polyaspartic acid, as a plant nutrition absorption promoting agent, has a remarkable effect indeed, is suitable
for a variety of plants and soil, and its main characteristics used together with chemical fertilizer displays in:
Characteristic 1: Reduce the loss of chemical fertilizer, activate nutrient elements and improve the utilization
rate of the chemical fertilizer, thus reduce 30% of the using amount of the chemical fertilizer, and increase
10% - 30% of the yield.
Characteristic 2: Promote the crops to absorb the trace elements such as iron, zinc, manganese, etc.
Comparing with the other crops, the crops treated by using polyaspartic acid content more than 3 to 4
times of the trace elements.
Characteristic 3: Promote the crop ripe 7-10 days earlier, prolong the harvest time for 10-15 days.
Characteristic 4: Promote root growth and enhance the resistance.
2. The industrial special polyaspartic acid is widely used as the corrosion inhibitors in the water treatment
fields such as industrial cooling circulating water, reverse osmosis water, back injection water in oil field,
metal cutting fluid, and boiler and steam pipeline; It can also be used as dispersant in papermaking, printing
and dyeing and washing industry. Polyaspartic acid has an outstanding performance in the systems of high
hardness, high alkalinity, high PH value and high concentration multiple. Its scale inhibition effect is better
than that of the commonly used scale inhibitors containing phosphine. Using this product instead of water
treatment agent containing phosphine, can avoid the water eutrophication and the secondary pollution in
the process of discharge.
Package & Storage
The product is packed by plastic drums, 25 kg or 250 kg per barrel, and also can be packed according to
the needs of the customers. It should be stored inside the ventilated storeroom, and the storage period is
ten months.
Safety Protection
This product should be avoided to contact eyes, skin or the clothes. Once it is splashed to body, rinsed
immediately with plenty of water.
Hydrolysis precursor of the polyaspartic acid——Poly (succinimide) (PSI), also supply solid polyaspartic acid.
