High temperature plastic fluorescent pigment

High temperature plastic fluorescent pigments offer brilliant colors, intense fluorescence, good dispersibility. They are free from formaldehyde,heavy metals and prohibited aromatic amines. They can withstand temperature of 260℃,with some grades can withstand up to 280℃,making them suitable for high temperature plastic coloring.

Key features

• Heat resistance up to 350°C (short-term) — suitable for engineering plastics.
• Bright, vivid fluorescence under UV / black light.
• Low migration and excellent color fastness in polycarbonate, PBT and PPS.
• Compatible with injection molding, extrusion and compounding.
• Available as powder pigment and masterbatch concentrate.

Applications

Suitable for various high temperature plastic coloring with processing temperature ≤280℃.

Package

Packed in composite paper bag within PE film bag, placing in a carton, net weight 22.68 kg

Handling & Processing Notes

• Avoid prolonged residence at peak melt temperatures to reduce potential color change.
• Drying may be required for certain masterbatches before processing.
• Blend masterbatch into polymer prior to feeding for uniform dispersion.
• Test for compatibility and migration with final substrate prior to large-scale production.

Frequently Asked Questions

What plastics are suitable for this pigment?

Typical compatible resins include engineering plastics such as PC, PBT, PPS, PETG and high-temperature nylons. Compatibility depends on grade — conduct trials for your formulation.

How do I choose between powder and masterbatch?

Powder pigments are good for lab trials and custom compounding. Masterbatches offer easier dosing, better dispersion and are preferred for high-volume manufacturing.

What is the recommended pigment loading?

Start with 0.1–0.5% and adjust up to 3.0% depending on desired brightness and polymer type. High loadings may affect mechanical properties — test accordingly.
