Polyanionic cellulose pac price

When sourcing Polyanionic Cellulose, you must prioritize the Degree of Substitution (DS), which should ideally be above 0.9 for high-end applications to ensure superior salt resistance. Additionally, verify the purity level (typically ≥95% for premium grades) and the viscosity profile. PAC is generally categorized into PAC-LV (Low Viscosity) for fluid loss control without significant thickening, and PAC-HV (High Viscosity) for both filtration control and rheology enhancement. Ensure the moisture content is below 10% to prevent caking during storage.

PAC is a versatile polymer primarily used in oil and gas drilling as a high-performance filtration reducer and tackifier in water-based drilling fluids. It is also essential in mining for ore processing, civil engineering for trenchless digging, and even in the food and pharmaceutical industries (if USP/BP grade) as a stabilizer. For B2B buyers, it is crucial to match the grade (Technical, Industrial, or Food Grade) to the specific application to ensure chemical compatibility and cost-efficiency.

A professional supplier must comply with API Spec 13A (American Petroleum Institute) or OCMA standards for oilfield applications. Look for manufacturers with ISO 9001:2015 for quality management and ISO 14001 for environmental standards. If the product is intended for international markets, ensure the supplier provides a comprehensive Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch to facilitate customs clearance and safety audits.

To achieve the best Total Cost of Ownership (TCO), buyers should negotiate based on active content rather than just gross weight. Purchasing in bulk (20ft FCL) typically reduces unit costs by 15-25% compared to LCL. Furthermore, consider the packaging durability; opting for multi-layer paper bags with PE liners or 750kg-1000kg jumbo bags can prevent moisture ingress, reducing waste and long-term storage losses.

The most significant risk is quality inconsistency between the sample and the bulk order. To mitigate this, use third-party inspection services (like SGS or Intertek) to perform pre-shipment testing on viscosity and purity. Another risk is moisture damage during sea transit; ensure the contract specifies seaworthy packaging and the use of desiccants within the container.

Focus on transparency regarding raw material costs (such as refined cotton and monochloroacetic acid prices). Request a fixed-price agreement for a set period or a formula-based pricing model to avoid sudden spikes. For reliable sourcing, platforms like Made-in-China.com allow you to filter for 'Audited Suppliers', providing an extra layer of verification regarding the factory's production capacity and export history.

Always use Secure Payment terms such as Letter of Credit (L/C) or Escrow services for first-time large orders. Regarding logistics, PAC is generally classified as non-hazardous cargo, but you must ensure the supplier provides a 'Non-Hazardous Chemical Declaration' to avoid shipping delays. For shipping to regions with high humidity, prioritize FOB terms if you have a trusted freight forwarder who can guarantee container integrity.
