Traffolyte and engraved acrylic are the two most common materials for engraved labels in Australia — and they are frequently confused. They look similar, both laser engrave well, and both show up in electrical, industrial, and signage jobs. But they are not interchangeable, and picking the wrong one for the job is a common source of failed labels.
This guide breaks down the differences between traffolyte and engraved acrylic — what each is made of, where each performs best, and how to choose for your specific job.
What is Traffolyte?
Traffolyte is the common Australian name for engraving laminate — a multi-layer phenolic or ABS-based plastic sheet. A thin coloured cap layer is bonded to a contrasting core layer; engraving removes the cap to reveal the core underneath.
- Materials: Phenolic or ABS base with a coloured surface cap layer
- Common thicknesses: 0.8mm, 1.5mm, 3mm
- Best for: Electrical switchboard labels, equipment identification, safety signs, circuit tags
- Engraving method: Laser or rotary engraving removes the cap layer
What is Engraved Acrylic?
Engraved acrylic uses a solid coloured or clear acrylic sheet that is marked by laser engraving. The laser either fills the surface (frosted engraving on clear acrylic) or ablates a coloured top coat on dual-layer acrylic.
- Materials: Cast or extruded acrylic (PMMA) — solid coloured, clear, or dual-layer
- Common thicknesses: 1.5mm, 3mm, 5mm, 10mm
- Best for: Display signage, reception signs, awards, premium branding, architectural wayfinding
- Engraving method: Laser engraving or surface painting techniques
Head-to-Head Comparison
| Property | Traffolyte | Engraved Acrylic |
|---|---|---|
| Primary use | Industrial / electrical ID | Signage, display, awards |
| Contrast | High (dual-layer by design) | Variable — depends on finish |
| UV resistance | Good to excellent | Good (may yellow over decades) |
| Heat resistance | Up to ~100°C | Softens at ~90°C |
| Chemical resistance | Good — resists oils and cleaners | Poor with solvents, alcohol, petrol |
| Impact resistance | Moderate | Brittle — can crack on impact |
| Typical thickness on switchboards | 1.5mm (label wells) | Not standard |
| Inspector acceptance for switchboards | Yes — the Australian standard | Not typically accepted |
| Cost | Lower per label | Higher — especially thick acrylic |
| Edge finish | Clean laser edge | Polished or flame-polished |
When to Choose Traffolyte
Traffolyte is almost always the right choice for:
- Switchboard labelling — circuit IDs, main switch labels, warning labels. Required for AS/NZS 3000 compliance on most commercial and industrial installations.
- Equipment identification — asset tags, cable tags, valve tags.
- Safety signage — danger, warning, caution, instruction labels in industrial environments.
- Control panels — button labels, selector switch identification, pilot light legends.
- Any job where the label needs to last 20+ years without maintenance.
When to Choose Engraved Acrylic
Acrylic is the better choice for:
- Reception and lobby signs — where the visual premium and depth of a thicker material matters.
- Award plaques — clear or frosted acrylic looks more considered than traffolyte.
- Architectural wayfinding — room numbers, donor walls, directional signage in corporate environments.
- Backlit signage — clear acrylic with reverse engraving lit from behind.
- Display and retail — where the sign is decorative as well as functional.
Common Mistakes
Using Acrylic on a Switchboard
Acrylic looks fine day one, but softens in hot switchboard enclosures and can crack if the board is hit or knocked. It also reacts to some electrical cleaners. Inspectors generally won't accept it for AS/NZS 3000 compliance work.
Using Traffolyte for Premium Signage
Traffolyte is a workhorse material — it shows its layered construction on the edges and doesn't have the depth or optical quality of cast acrylic. Not the right look for a boardroom reception sign.
Confusing Engraved Laminate with Plain Plastic
"Engraved plastic" labels can mean anything — some are just printed plastic with laser-marked text. These fade and scratch. True traffolyte has a layered construction that reveals contrasting colour when engraved.
How to Tell Them Apart
If you're looking at an existing label:
- Look at the edge — traffolyte shows a visible layer line (cap over core). Solid acrylic is uniform through the thickness.
- Check the engraving depth — traffolyte has a very consistent shallow engraving (just through the cap). Acrylic engraving can be deeper and has a more variable finish.
- Feel the weight — at the same thickness, acrylic feels heavier and more rigid.
- Try a drop of solvent (discreet spot) — acrylic will haze with alcohol or acetone; traffolyte won't.
