Solvent blue 36 price manufacturers

Solvent Blue 36 is an anthraquinone derivative primarily used for coloring plastics and fibers. Buyers must verify the purity level (typically ≥98%), melting point (160-165°C), and moisture content (≤0.5%). For high-end applications, ensure the heat resistance is rated at 260°C-300°C to prevent degradation during injection molding or extrusion processes.

The choice depends heavily on the substrate. For polystyrene (PS), ABS, and polycarbonate (PC), Solvent Blue 36 is preferred due to its excellent transparency and lightfastness (Grade 7-8). If you are using it for ink manufacturing or wood stains, you must confirm its solubility in organic solvents like ethanol, acetone, or xylene to ensure a stable, sediment-free solution.

As a chemical dye, it must comply with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the EU market and TSCA for the US. Ensure the supplier provides a comprehensive Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. If used in food-contact plastics, it must meet FDA or EU 10/2011 migration limits.

Price is often dictated by the dye strength (concentration). A lower-priced product may have a lower concentration, requiring more pigment to achieve the desired hue, which increases the total cost of coloring. Request a color matching test or a 100g sample to compare the tinting strength against a standard reference before committing to bulk orders.

The primary risks include batch-to-batch color inconsistency and customs delays due to improper labeling. To mitigate this, use Made-in-China.com's Secured Trading services and insist on pre-shipment inspection (PSI). Ensure the packaging is UN-certified for hazardous or chemical goods to prevent leakage during maritime transit.

Negotiate based on annual volume rather than spot orders to secure a 'Contract Price.' Ask for tiered pricing (e.g., 500kg vs. 2 tons). Since raw material costs for anthraquinone fluctuate, consider a price adjustment formula linked to market indices to maintain a fair long-term partnership.

Solvent Blue 36 is usually classified as non-hazardous for transport in many jurisdictions, but this must be verified by the DGM (Dangerous Goods Management) report. Use FOB (Free On Board) terms to maintain control over the freight forwarder, and ensure the goods are stored in a cool, dry, and well-ventilated warehouse during transit to prevent clumping.

Always verify the supplier's Business License and Export Qualification on Made-in-China.com. Utilize Letters of Credit (L/C) for large transactions or Escrow-based payment systems where funds are only released upon the buyer's confirmation of receiving goods that match the COA specifications.
