This guide outlines essential considerations when sourcing these products, addresses common FAQs, and highlights why Hebei Xiangdu Chemical should be your go-to partner.  

Understanding Polyaspartic Acid Derivatives: Applications & Benefits

Polyaspartic acid is a biodegradable, water-soluble polymer renowned for its versatility across industries. Its derivatives—sodium polyaspartate, polyaspartic acid potassium salt, potassium polyaspartate, polyaspartic acid calcium salt, and polyaspartic acid zinc salt—are engineered for specific applications, from agriculture to water treatment. Below, we break down their unique properties and uses.

Sodium Polyaspartate: The Chelation Powerhouse

Sodium polyaspartate excels as a heavy metal chelator in wastewater treatment and detergents. Its high biodegradability (over 90% within 28 days) makes it ideal for eco-conscious industries. For wholesalers, verify the product’s purity (≥95%) and compliance with REACH or EPA standards. Hebei Xiangdu Chemical’s 15,000-ton annual production capacity ensures scalability for bulk orders.

Polyaspartic Acid Potassium Salt & Potassium Polyaspartate: Agricultural Innovations

These potassium-rich derivatives enhance fertilizer efficiency by preventing nutrient leaching. They also act as soil conditioners, improving crop yields. When sourcing, prioritize suppliers with certifications like ISO 9001 and OMRI (for organic farming compatibility). Hebei Xiangdu holds 22 patents, including formulations optimized for pH stability.  

Polyaspartic Acid Calcium Salt: Food & Pharma Grade Solutions

Used as a calcium fortifier in functional foods and drug delivery systems, this derivative demands strict adherence to FDA or EFSA guidelines. Confirm that your supplier provides third-party lab reports for heavy metal content and microbial limits.  

Polyaspartic Acid Zinc Salt: Corrosion Inhibition

Widely used in cooling water systems and coatings, this derivative offers superior corrosion protection compared to traditional phosphates. Ensure its zinc content aligns with industry benchmarks (e.g., 10–15% for industrial applications).  

Critical Factors for Wholesalers: Quality, Compliance & Logistics  

Certifications & Regulatory Compliance  

Verify that sodium polyaspartate and other derivatives meet regional regulations. For example, the EU’s Detergent Regulation (EC 648/2004) mandates biodegradability thresholds. Hebei Xiangdu’s products comply with international standards and hold patents in the U.S., Canada, and Europe.

Batch Consistency & Shelf Life  

Polyaspartic acid derivatives must maintain consistent viscosity, pH, and solubility across batches. Request Certificates of Analysis (CoA) for each shipment. Shelf life typically ranges from 18–24 months when stored in cool, dry conditions.  

Packaging & Shipping Requirements  

Bulk orders of potassium polyaspartate or polyaspartic acid zinc salt often require moisture-resistant packaging (e.g., 25kg HDPE drums). Partner with suppliers offering flexible logistics solutions, including FOB or CIF terms. Hebei Xiangdu exports to 30+ countries, ensuring timely delivery.

Pricing & MOQs  

Negotiate volume-based discounts for polyaspartic acid calcium salt or sodium polyaspartate. Minimum Order Quantities (MOQs) typically start at 1 ton for standard grades. For customized formulations (e.g., higher zinc content), MOQs may increase.
