Main Applications

Industrial Circulating Water Systems: Polyaspartic Acid efficiently chelates calcium, magnesium, barium and strontium scale ions, inhibiting scale crystal formation and adhesion. Its scale prevention effect is 3-5 times better than traditional polymers, and Polyaspartic Acid also prevents pipe blockage and equipment scaling, ensuring stable system operation and reducing energy consumption, and is suitable for steel, chemical and electric power circulating water conditions.
Reverse Osmosis (RO) Membrane Protection: Polyaspartic Acid forms a protective layer on RO membrane surfaces, slowing scale and salt deposition, preventing pore blockage and extending membrane lifespan by over 40%. It reduces membrane replacement and maintenance frequency, lowering water treatment costs, and the mild formula of Polyaspartic Acid causes no damage to membrane module structures.
Oilfield Water Injection Systems: Polyaspartic Acid has excellent high-temperature, high-pressure and salt resistance, maintaining stable scale and corrosion inhibition under extreme oilfield conditions, preventing scale in injection pipelines and reservoirs. Polyaspartic Acid also improves reservoir permeability and oil recovery, meeting large-scale oilfield production needs and complying with environmental water treatment standards.

Nutrient Slow-Release Carrier: Polyaspartic Acid forms stable complex structures with nitrogen, phosphorus and potassium through active groups, slowing nutrient release in soil. It extends fertilizer effect by 30-50%, reducing fertilization times and nutrient loss, lowering planting costs, while improving crop nutrient absorption, promoting balanced growth and significantly increasing crop quality and yield.
Soil Conditioner: Polyaspartic Acid effectively chelates soil heavy metal ions (lead, cadmium, mercury), forming insoluble complexes to reduce their harm to crops. It improves soil aggregate structure, breaks compaction, enhances water and fertilizer retention and regulates pH, upgrading arable land quality and suitable for improving barren and heavy metal-polluted land.
Foliar Fertilizer Enhancer: Polyaspartic Acid acts as a high-efficiency foliar fertilizer enhancer, reducing solution surface tension and increasing nutrient penetration through crop leaf stomata. It raises nutrient utilization by 20-35%, cutting foliar fertilizer usage while ensuring efficacy, and is suitable for grains, fruits and vegetables with the advantages of safety, efficiency and no residue.

Safe Chelating Agent: Polyaspartic Acid directly replaces harmful chelating agents such as EDTA in cosmetics, being non-irritating, non-allergenic and skin-friendly. It effectively chelates free metal ions in formulations, preventing product oxidation and discoloration, improving storage stability and providing a gentler, safer formula option for cosmetic R&D—making Polyaspartic Acid a preferred choice for green cosmetic formulations.
Skin Conditioning Agent: Polyaspartic Acid has excellent skin affinity and moisturizing properties, forming a breathable water-locking film on the skin. It promotes deep skin penetration of whitening and anti-aging active ingredients, and Polyaspartic Acid also improves product texture, reduces stickiness and enhances stability, reducing active ingredient loss and significantly optimizing the performance of skincare and makeup products.
Environmentally Friendly Anti-corrosion Enhancement: Polyaspartic Acid synergizes with natural preservative systems (plant extracts, essential oils) in cosmetics, enhancing broad-spectrum antibacterial effects and extending shelf life. This synergy eliminates excessive chemical preservatives, reducing skin irritation while maintaining environmental friendliness, fully meeting modern consumers' green cosmetics demands.

Environmentally Friendly Descaling Agent: Polyaspartic Acid is the core ingredient of industrial eco-friendly descaling agents, decomposing and removing scale on heat exchangers, boilers and pipes through chelation and dispersion. It leaves no residue after cleaning, and its mild formula does not corrode metal surfaces or precision components. Polyaspartic Acid meets national environmental emission standards and significantly reduces enterprise cleaning and environmental treatment costs.
Metal Surface Treatment: Polyaspartic Acid acts as a high-performance phosphate-free pretreatment agent, completely replacing traditional phosphorus-containing metal treatment products. It removes oxide layers, oil and impurities on metal surfaces, forming a uniform protective film via adsorption. This film enhances coating adhesion and corrosion resistance, and is suitable for automotive, hardware and home appliance industries, meeting phosphate-free environmental standards.
Detergent Enhancement: Polyaspartic Acid maintains excellent performance in high-hardness water, quickly chelating calcium and magnesium ions to prevent scale buildup and detergent inactivation. It improves the cleaning efficiency of industrial and household detergents, reduces surfactant usage and lowers production costs, and Polyaspartic Acid is suitable for industrial parts cleaning, textile washing and daily household cleaning.

Environmentally Friendly Packaging Materials: Using Polyaspartic Acid as the core raw material with biodegradable polymers, fully biodegradable films, coatings and packaging products (food bags, fresh-keeping films) can be produced. These products degrade into carbon dioxide and water in nature, leaving no harmful residues and eliminating plastic white pollution. Its-based packaging is suitable for food and agricultural products, aligning with low-carbon packaging trends.
Medical Sustained-Release Materials: Polyaspartic Acid meets medical grade standards for biocompatibility, biodegradability and non-toxicity, and is used as a biodegradable drug carrier to achieve slow drug release at lesion sites, improving efficacy and reducing medication frequency. It is also used to prepare tissue engineering scaffolds, meeting personalized biomaterial needs. Its-based medical materials degrade in the human body, reducing medical waste and ensuring biological safety.
Agricultural Mulch Film: Agricultural mulch film made with Polyaspartic Acid and other biodegradable materials is fully biodegradable for all planting scenarios. This mulch film requires no manual recycling, decomposing into harmless substances via soil microorganisms and returning to the soil. It avoids traditional plastic mulch damage to soil and crops, eliminating agricultural white pollution, and its-based mulch film supports green ecological agricultural development.
