Because of its good dispersion to inorganic and organic compouds, PASP has been applied with different degree in pharmaceuticals, pigments, paints, leather, inorganic chemicals, oilfield chemicals and other fields.PASPis called "third-generation polyurea", it can be used to produce protective coatings of high weather resistance, high resistance to chemical corrosion, fast-curing paint, and applied directly to fast curing coatings on the metal substrate and industrial flooring, etc., ; it can be used in the tanning process as tanning agents, produces biodegradable leather; pharmaceutical carrier material made from PASP has been widely used in family planning, anti-tumor drugs making etc.

Poly-L-aspartic acid sodium salts (poly(L-Asp), poly(L-Aspartic acid sodium salt)) are synthetic, negatively charged polyamino acids with one Na per aspartic acid unit. They are water-soluble and can exist as block copolymers.
Specification:
CAS No.: -40-6
Formula: (C4H5NO3Na)n
Molecular Weight: 5,000-8,000
Appearance: Light yellow powder
PolyAspartic Acid Sodium Salts (PASP-Na): 90% min.
Moisture: 10% max.
pH: 7.5~10.5 (10 g/L solution)
Limiting Viscosity dl/g (30℃): 0.055~0.090
Source of Raw Material: L-Aspartic Acid
Characteristics:
1. Highly water-soluble
2. Phosphate-free
3. Non-hazardous and non-polluting
4. Completely biodegradable
5. Can self-assemble into particles with hydrophobic cores and hydrophilic shells
Applications:
1. Surface Coating: Used in layer-by-layer deposition techniques for surface coating.
2. Corrosion Inhibitor: Inhibit scale and corrosion in industrial recirculating water, boilers, and steam lines.
3. Oil and Mineral Exploration Auxiliary: Replace complexing agents in detergents, serve as a thinner for drilling fluid, and inhibit scale corrosion in reinjection water and pipelines.
4. Cleaning Detergent: Enhance water's soil-carrying capacity, prevent surfactant activity loss in hard water, and act as a dispersant in low-phosphate and phosphate-free detergents.
