Flame Retardant Polyimide Label Material Features 

Flame Retardant Polyimide Label Material by Vizlent is engineered for printed circuit board assembly and other electronics processes where labels must survive aggressive thermal exposure.

Polyimide film maintains its physical integrity through wave soldering, infrared and convection reflow, and lead-free solder profiles peaking around 260 °C, with short-term excursions tolerated up to 300 °C.

The face stock combines flame retardancy with a high-temperature silicone or acrylic adhesive that bonds reliably to PCB laminates, ceramic substrates, and metal heat spreaders without flowing or off-gassing significantly during reflow.

The resulting polyimide label material retains barcode legibility for full traceability from PCB fab through field service.

Frequently Asked Questions

Can VIZLENT supply polyimide labels in custom sizes for tight PCB real estate?

Yes. We routinely die-cut polyimide labels down to 4 × 4 mm and can supply tighter geometries on request to fit constrained PCB layouts. Sheet, fan-fold, and roll formats are available so the labels feed reliably into your existing print-and-apply equipment.

Will the labels survive lead-free reflow soldering profiles peaking at 260 °C?

Yes. Our flame retardant polyimide label material is qualified to withstand multiple passes through standard lead-free reflow profiles peaking around 260 °C, with the face stock and adhesive maintaining adhesion and barcode legibility. Short-term excursions to about 300 °C are tolerated for processes such as solder repair.

What is the MOQ and lead time for wholesale polyimide label orders?

The standard MOQ is 2,000 pieces per SKU to cover material setup and registration on our die-cutting line. Lead time is typically 10–15 working days after artwork approval, and we can support pilot batches for new customer qualification on case-by-case terms.

How critical is the UL 94 V-0 flame rating in a polyimide label, and is it documented?

For PCBs and battery packs the flame rating is one of the most critical attributes because the label sits permanently inside the assembly. VIZLENT sources polyimide film rated to UL 94 V-0 and can provide manufacturer test data and UL file references during the qualification process.

Is the material compatible with thermal transfer and laser marking workflows?

Yes. The face stock is engineered to accept resin thermal transfer ribbons and CO2 or fiber laser marking, producing high-contrast 1D and 2D codes that survive reflow without smudging. We can recommend ribbon grades and laser parameters once we know the specific equipment models in your line.
