Sodium Salt of Polyaspartic Acid (PASP) is a high-performance, biodegradable biopolymer renowned for its exceptional versatility in industrial water treatment and chemical synthesis. Featuring a sophisticated molecular structure rich in amido bonds and carboxyl groups, PASP offers superior hydrophilicity and chemical stability, making it a sustainable, green alternative to traditional phosphorus-containing scale inhibitors.
By forming stable complexes with multivalent metal ions, PASP effectively prevents the precipitation of scale and corrosion in harsh environments. Its excellent biodegradability ensures that it avoids eutrophication and secondary pollution, meeting the most stringent environmental standards across agriculture, petroleum exploitation, and detergent manufacturing industries.

Frequently Asked Questions
PASP is a biodegradable biopolymer, meaning it breaks down naturally without causing eutrophication in water bodies, unlike phosphorus-based chemicals which can lead to harmful algal blooms.
When added to urea, PASP can increase fertilizer efficiency by 20-40%, reducing the required dosage while enhancing nutrient absorption and promoting root growth in crops.
Yes, due to its amido peptide bonds, PASP possesses high chemical and thermal stability, making it resistant to decomposition at high temperatures.
PASP acts as an excellent corrosion inhibitor for oil pipelines, specifically preventing corrosion caused by carbon dioxide and reducing fluid viscosity in bentonite mud.
Absolutely. Its anionic surfactant properties allow it to soften water and prevent the re-contamination of greasy dirt on clothes and dinnerware during cleaning.
PASP is alkaline. It should be stored in a shady, dry place for up to ten months. Operators should use protective gear to avoid skin and eye contact.
