Flame retardant labels and halogen-free materials

In aerospace, automotive, and electrical infrastructure, fire safety is non-negotiable. We source specialized flame retardant label materials designed to create a protective char layer when exposed to extreme heat, controlling heat transfer and suppressing the release of flammable gases.

  • Forms a protective char layer to prevent fire propagation
  • Halogen-free options available to meet environmental standards
  • Durable Polyimide (PI) and Polyester (PET) face stocks
  • Tested to strict industry flammability standards (UL, FAR, etc.)

How flame retardant labels work

Unlike standard labels that melt or ignite when exposed to fire, flame retardant materials undergo a chemical reaction. They are engineered to char, creating a thermal barrier that deprives the fire of oxygen and slows the transfer of heat to the underlying component.

This critical delay can prevent localized electrical shorts or battery thermal runaways from escalating into catastrophic fires.

Halogen-free and environmentally conscious

Historically, flame retardancy was achieved using halogenated compounds, which can release toxic and corrosive gases when burned. We supply modern, halogen-free flame retardant materials from manufacturers like Polyonics.

These halogen-free materials meet strict REACH and RoHS compliance while still providing top-tier fire suppression performance.

Applications

Flame retardant labels are essential for EV battery packs, wire and cable marking in aerospace, power supplies, and high-voltage electrical panels.

Contact our custom labels team with your specific environmental requirements and required certifications (such as UL94 V-0 or FAR 25.853), and we will source the correct material for your application.

FAQ

What is the difference between flame retardant and high-temperature labels?

High-temperature labels (like standard Polyimide) are designed to survive heat (e.g., in an oven or reflow process) without melting or losing their print. Flame retardant labels are specifically designed to actively resist ignition and suppress flames if a fire actually occurs.

Do you offer flame retardant labels for wire marking?

Yes. We can source flexible flame retardant materials, such as specialized nylon or flexible polyimide, that are designed to wrap around wires and cables without flagging or unwinding.
