If you have ever specified labels for a control panel, switchgear or plant room, you will almost certainly have seen the word Traffolyte. It is one of the most common materials for engraved identification labels in the UK, but the name causes some confusion. This guide explains what Traffolyte actually is, where it performs well, and when another material is a better fit.
Where the name comes from
Traffolyte started life as a brand name. It was first produced in 1927 by Metropolitan-Vickers Electrical at Trafford Park in Manchester, which is where the name comes from. The original brand eventually fell out of use, but the word stuck. Today "Traffolyte" is used across the industry as a generic term for engraving laminate, much like people say "Hoover" for a vacuum cleaner.
That matters when you order. Some buyers use "Traffolyte" to mean a traditional phenolic laminate specifically. Others use it to mean any layered engraving plastic, including modern acrylic laminates. If your specification depends on one or the other, say so on the drawing or order.
How Traffolyte is made
Traditional Traffolyte is a phenolic laminate: layers of resin-impregnated material bonded together under heat and high pressure. The surface layer is one colour and the core is a contrasting colour. When the surface is engraved away, the core shows through, giving permanent, high-contrast text and symbols.
Because the text is cut into the material rather than printed on top, it cannot rub off or fade in the way ink can. Common colour combinations include white text on black, black on white, white on red for warnings, and white on blue or green for mandatory and safe-condition labels.
Where Traffolyte works best
Traffolyte is the default choice for many indoor electrical and mechanical applications:
- Control panels and fascias — push-button legends, selector switches, indicator lamps
- Distribution boards and switchgear — circuit identification, isolator and fuse labels
- Plant rooms — equipment, pump and valve identification (see our HVAC and plant room labelling guide)
- Warning and instruction labels — where a permanent, rigid label is preferred over a sticker
It is rigid, light, electrically insulating and resists everyday handling, cleaning and most workshop environments. It is also quick to produce in small batches, which makes it cost-effective for one-off panels and site work. For what typically needs labelling on an electrical installation, see our guide to electrical panel labelling and BS 7671.
Where Traffolyte is not the right choice
Traffolyte has limits, and it is better to know them before you order:
- Prolonged outdoor and UV exposure — standard Traffolyte is not recommended for long-term sunlight. Colours can fade and the surface can degrade over time.
- Marine, chemical washdown or high-abrasion areas — metals are usually the safer option.
- Very high temperatures or fire-critical locations — check the material data sheet against your requirement rather than assuming.
Traffolyte vs acrylic vs metal
| Material | Best for | Outdoor / UV | Typical marking method |
|---|---|---|---|
| Traffolyte (phenolic laminate) | Indoor panels, switchgear, plant rooms | Not recommended long term | Mechanical engraving |
| Acrylic laminate | Indoor labels; UV-stable grades for outdoor use | Better with UV-stable grades | Laser engraving |
| Anodised aluminium | Machinery, outdoor equipment, lightweight plates | Good | Laser, ano-print, engraving |
| 316L stainless steel | Marine, chemical, outdoor and long-life plates | Excellent | Chemical etching, laser annealing |
If your labels will live outdoors or in harsh conditions, look at our anodised aluminium labels or 316L stainless steel labels instead. For a full comparison of every material we offer, see our industrial engraved labels buying guide.
What to send us for a Traffolyte quote
To quote accurately, we need:
- The text for each label (a spreadsheet is ideal for large schedules)
- Label sizes, or the space available on the panel
- Colour combination (for example, white on black)
- Text height and font, if you have a standard to match
- Fixing method: self-adhesive, screw holes or both
- Quantity and any deadline
If you are replacing existing labels, a photo with a ruler in shot helps us match size, colour and layout.
