Types of PASP
| Feature | PASP Liquid | PASP Powder |
| Active Content | 40% (ready-to-use) | 94% – 96% (high purity concentrate) |
| How to Use | Pour directly into water. No mixing needed. | Must dissolve in water first before use. |
| Best For | • Daily water treatment dosing • Easy on-site use • Cooling towers, boilers | • Long distance export • Cold climates (no freezing risk) • Agriculture, daily chemical additives |
| Storage | Simple. Keep container sealed. | Must keep dry. Moisture causes caking. |
Simple Choice Guide:
Choose PASP Liquid if you want ready-to-use convenience. Just open and dose. No dissolving time. Great for daily water treatment operations.
Choose PASP Powder if you ship long distance, need lower transport cost, or operate in cold climates where liquid may freeze. Also best if you blend your own formulations.
Sodium of Polyaspartic Acid Uses
Water Treatment: PASP effectively controls scale and corrosion in high hardness, high alkalinity, and high pH water systems. It is widely used in cooling towers, boilers, oilfields, and reverse osmosis systems.
Detergents: PASP is non-phosphorus and fully biodegradable, making it safe for the environment. It is used as a water softening ingredient in modern, eco-friendly laundry detergents and cleaners.
Agriculture: Added to fertilizers, PASP helps plants grow stronger roots. It improves the uptake of nitrogen, phosphorus, and potassium, increasing fertilizer efficiency and crop yields.
Personal Care: Stabilizes and moisturizes shampoos, gels, and cosmetic products.
Oilfield Operations: PASP works as a thinner for drilling fluid, helping to improve flow and performance. It also prevents scale and corrosion in reinjection water and pipelines.
FAQ of Sodium of Polyaspartic Acid
Yes. PASP works well with zinc for better corrosion control. It is also stable with chlorine in most cooling water systems.
Yes. PASP is phosphorus-free and fully biodegradable. It breaks down naturally and does not cause water pollution.
We provide Certificate of Analysis (CoA) for every batch. It confirms active content, pH, density, and biodegradability data.
Yes. It is safe and effective. Many eco-friendly detergents now use PASP as a water softener and anti-ash agent.
