Polyonics is a specialty coatings manufacturer, not a label printer. We engineer the materials that make electronic component labels survive reflow soldering at 572°F (300°C), wave soldering, aggressive flux chemistries, and the full PCB assembly process. Our Apex Series delivers 72% greater flux solder resistance than our previous generation.
OEMs, contract manufacturers, and converters evaluating material options will find the full picture here, including exactly how Polyonics differs from catalog suppliers.
Most label suppliers pull materials from a catalog. Polyonics develops its topcoat chemistry in-house at our Westmoreland, NH facility and applies it to polyimide films to create constructions purpose-built for your process. Here is how that difference plays out in the specs that matter.
+72% vs. previous generation (Apex Series)
+15% vs. previous generation
reliable adhesion and barcode readability up to 572°F (300°C)
IPA, MEK, no-clean, water-soluble and rosin-based fluxes, aqueous cleaners
proprietary topcoat maintains print legibility through handling, assembly, and field exposure
Polyonics label materials have been tested and approved against leading flux and cleaning chemistries used in PCB assembly, including formulations from Alpha Metals, Kester, Kyzen, and Zestron. While some catalog suppliers test against selected cleaning agents, Polyonics’ approvals span both the flux-formulation side (Alpha Metals, Kester) and the cleaning-chemistry side (Kyzen, Zestron), covering the full process-chemistry picture in a single qualified material.

Polyonics materials are engineered for the real-world conditions your labels face across the full electronics manufacturing chain.
Industrial Electronics: SGS-tested V-0 flame-retardant constructions for power supplies, industrial controllers, and automotive ECUs where flammability compliance is mandatory.
Consumer Electronics Identification: Durable component labels for devices where small font sizes, tight tolerances, and long product lifecycles require materials that stay legible from assembly through end-of-life.
Industrial Electronics: V-0 rated, flame-retardant constructions for power supplies, industrial controllers, and automotive ECUs where UL flammability compliance is mandatory.
Component Tracking Throughout the Supply Chain: Serialized barcodes, 2D codes, and human-readable text that remain scannable after reflow, cleaning, handling, and years of field exposure, supporting full lot-level and unit-level traceability in electronics manufacturing.
For procurement and engineering teams evaluating supplier qualification, here is an overview of the compliance and standards coverage Polyonics materials support.

Polyonics label materials are tested to withstand temperatures up to 572°F (300°C), making them suitable for lead-free reflow soldering, wave soldering, and other high-heat electronics manufacturing processes.
Our proprietary topcoat anchors printed barcodes and small text against flux, solvents, and aqueous cleaning agents. The Apex Series delivers 72% greater flux solder resistance and 15% better cleaner resistance compared to previous generations.
Yes. Polyonics manufactures anti-static label materials designed to prevent electrostatic discharge during handling and assembly. These are available on select constructions across our product lines, including the Apex Series, and meet ANSI/ESD S20.20, ESD S541, IEC 61340-5-1, and JEDEC JESD 625B requirements.
Yes. We work with engineers and procurement teams to match the right film, topcoat, adhesive, and liner to your specific process, whether that involves a unique temperature profile, chemical exposure, or substrate challenge.
Polyonics offers UL-recognized materials and formulations designed to support RoHS and REACH compliance. Contact our team to confirm specific certifications for your application and region.
