Fluorescent pigment for plastic injection
Sourcing Fluorescent pigment for plastic injection from Nano Chemitek (China) Corp. - China Import Guide
Before ordering, verify the pigment’s chemical classification and thermal stability with the supplier. Request a sample batch tested for particle size distribution and lightfastness under ASTM D4303. Confirm compatibility with your specific resin grade, as performance varies between polyolefins and engineering thermoplastics. Do not assume certification claims without documented test reports.
Lead time is typically 15 to 25 days after order confirmation, depending on stock levels. Incoterms are usually FOB Shanghai, but CIF or DDP may be negotiable. Payment is commonly via T/T 30% advance and 70% against BL copy. Buyers should confirm whether the supplier accepts third-party inspection and request a pre-shipment report. Packaging must be moisture-sealed and labeled with batch number and expiry date.
Quality checks should include visual inspection for agglomeration, moisture content testing via Karl Fischer titration, and dispersion uniformity on a test injection mold. Request a certificate of analysis for each batch, including colorimetric data and residual solvent levels. For critical applications, arrange for independent lab testing of migration and lightfastness before full-scale production.
