Product Description
Chemical Name: Polyaspartic acid potassium salt (PASP-K)
Chemical Formula: C₄H₅NO₄(C₄H₄NO3Na)nK₂
CAS No.: 64723-18-8
▏Properties
Polyasparic acid potassium salt (PASP-K) is an artificial synthetic water soluble polymer of high molecular weight having the characteristics of no phosphorus, non-toxic, pollution-free and complete biodegradable. With the structure characteristics of peptide bond and active group such as carboxyl group, it has powerful functions such as chelate, dispersion, and adsorption,etc. and also good compatibility.
▏Composition
NO. | TEST | SPECIFICATION |
1 | PASP salts solid content | ≥ 93% |
2 | Moisture Content | <7% |
3 | Limiting Viscosity dl/g(30℃) | 0.040-0.070 |
4 | pH(10g/L in solution) | 8.0-10.0 |
5 | K2O+ Content | 22-25% |
6 | Biodegradable(28d) | ≥ 60% |
▏Applications
PASP-K is widely used as corrosion inhibitors in the water treatment fields such as industrial cooling water recirculating, reverse osmosis formulation, metal cutting fluid, and boiler and steam pipeline; It can also be used as dispersant in papermaking, printing and dyeing industries.
PASP-K has an outstanding performance in the systems of high hardness, high alkalinity, high PH value and high concentration. Its scale inhibition function is better than the traditional scale inhibitors containing phosphine.
Due to its characteristics of non-phosphorus and completely biodegradation, PASP-K can be used as a new water softening ingredient in the household detergent formulations and soft drinks,alcohol,wine etc.
