Cationic starch price

When sourcing Cationic Starch, the most critical parameter is the Degree of Substitution (DS), which typically ranges from 0.015 to 0.05. A higher DS improves the starch's affinity for negatively charged fibers. Additionally, you must verify the viscosity (measured in mPa.s), moisture content (ideally <14%), and pH value (usually 5.0-7.0) to ensure compatibility with your specific industrial application, such as papermaking or textile sizing.

Cationic starch is primarily derived from maize (corn), tapioca, or potato. Tapioca-based starch is often preferred for its superior film-forming properties and lower gelatinization temperature, though it may carry a premium price. Corn-based starch is generally the most cost-effective solution for high-volume industrial use. Buyers should choose based on the required ionic charge density and the specific mechanical strength needed for the end product.

For industrial applications, ensure the supplier complies with ISO 9001 for quality management. If the starch is used in food-contact packaging, it must meet FDA 21 CFR 176.170 or EU Regulation No 10/2011 standards. Always request a Technical Data Sheet (TDS) and a Material Safety Data Sheet (MSDS) to confirm the product meets international safety and environmental regulations.

It is predominantly used in the papermaking industry as a wet-end additive to increase internal bond strength and improve retention of fillers and pigments. In the textile industry, it serves as a sizing agent to improve weaving efficiency. It is also increasingly used in wastewater treatment as a flocculant due to its ability to neutralize negatively charged particles.

The price of Cationic Starch is highly sensitive to raw material crop cycles (corn/tapioca) and energy costs. To secure stable pricing, consider long-term framework agreements or purchasing during harvest seasons. On Made-in-China.com, you can utilize the Audit Reports to identify manufacturers with large-scale production capacities who are better equipped to absorb market fluctuations.

Cationic Starch is a fine powder and is susceptible to moisture absorption and microbial degradation. Ensure the supplier uses multi-layer moisture-proof bags (PE/PP) and provides palletized shipping with shrink wrap. During transit, containers must be kept cool and dry to prevent caking. Verify that the supplier can provide a Certificate of Analysis (COA) for every batch loaded into the container.

Always use Secured Payment services offered by reputable platforms like Made-in-China.com to protect your funds until delivery is confirmed. Before placing a bulk order, it is mandatory to request a pre-shipment sample for lab testing. For large contracts, hiring a third-party inspection agency (like SGS or Intertek) to perform a loading supervision and quality check at the factory is a highly recommended strategy to avoid receiving sub-standard chemicals.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate based on volume tiers (e.g., 20ft FCL vs. LCL) and ask for customized viscosity adjustments included in the price. Suppliers are often willing to offer a 5-10% discount for repeat orders or if you provide a clear annual procurement forecast, which helps them optimize their production schedule.
