Ceramic vs Carbon Tint PerthWhy the Label Misleads
They describe what a film is made from, not how well it performs. The number that separates them is TSER.
If you already know you want the coolest result, see our ceramic tint page; for a deeper matte look, compare carbon tint.
Carbon and ceramic describe what a film is made from, not how well it performs. They are manufacturing categories, not performance grades. Two films both sold as ceramic can behave very differently, and a good carbon ceramic film can beat a weaker ceramic one.
The clearest evidence is on our own shelf: Rayno Phantom S9 is a nano carbon ceramic film, which combines both technologies and breaks the versus framing entirely. Compare the exact series, its published TSER, and the finished legal VLT on your glass. Not the label.
Is Ceramic Tint Worth the Extra Cost?
Sometimes, but the label alone never justifies it. A strong carbon ceramic film can outperform a weaker ceramic one. Compare the published TSER of the exact shade, the finished VLT through your factory glass, and the warranty terms before paying more for a word.
Nano-ceramic films are non-conductive and generally offer strong infrared rejection with high clarity. That is a real advantage over dyed and metalised film. It is not automatically an advantage over a well-made carbon ceramic film.
Here is the proof, using two films we fit: Rayno Phantom S9-50 publishes 53% TSER at 50% VLT. SunTek CIR 20 Black publishes 58% TSER at 22% VLT. The SunTek rejects five points more heat, but it is more than twice as dark. If you were choosing on the word “ceramic” alone you would never see that trade.
Whether the upgrade is worth it depends on your glass area, how long the car sits in the sun and how much outward visibility you want to keep. It does not depend on which category the marketing puts it in.
What the Categories Actually Mean
Four constructions turn up in car tinting, and they differ in what blocks the heat, not just in price.
- Dyed film. A dye layer absorbs light. The cheapest construction, the weakest on heat, and the one that classically fades to purple as the dye breaks down.
- Metalised film. Metal particles reflect heat. Effective, but the metal layer can interfere with phone, GPS, radio and tyre-pressure signals, and it tends to look reflective. That matters in WA, where reflectance is capped at 10%.
- Carbon film. Carbon particles instead of metal. No signal interference, no purple fade, and a step up from dyed on heat and durability.
- Nano-ceramic film. Ceramic particles, non-conductive, generally the strongest infrared rejection with high clarity.
Then there is nano carbon ceramic, which layers both. Rayno Phantom S9 is one, which is precisely why “ceramic versus carbon” is the wrong question. The useful question is what the named product publishes.
Does Carbon Tint Fade or Turn Purple?
No, not in the way dyed film classically does. Purple fade is a dye problem: the colour layer breaks down under UV and shifts. Carbon film uses carbon particles instead, so it holds its colour. Carbon also avoids the signal interference that metalised film can cause.
That purple cast on an older car is almost always cheap dyed film reaching the end of its life. It is also the expensive kind to remove, because degraded adhesive comes off in flakes rather than sheets.
How the Constructions Compare
| Construction | Colour stability and signal |
|---|---|
| Dyed | The classic purple fade as the dye breaks down |
| Metalised | Holds colour, but the metal can affect phone, GPS and sensor signals |
| Carbon | Holds colour, no signal interference |
| Nano-ceramic and nano carbon ceramic | Non-conductive, no signal interference, highest clarity |
Longevity still depends on the exact product, the installation and the warranty terms, not on the category name. Ask which series is going on the car.
TSER Is the Number That Matters
TSER is total solar energy rejected: the share of the sun’s energy the film is published to reject. It is a better heat comparison than infrared rejection alone, because it accounts for more of the solar spectrum. And unlike “ceramic”, it is a number you can check.
Darker is not the same as cooler. That is the single most useful thing to take from this page, and the table below shows it in our own range.
Manufacturer-Published Figures
| Film | VLT | TSER | UV rejection |
|---|---|---|---|
| SunTek CIR 70 Black | 71% | 46% | >99% |
| SunTek CIR 35 Black | 35% | 52% | >99% |
| SunTek CIR 20 Black | 22% | 58% | >99% |
| Rayno Phantom S9-50 | 50% | 53% | >99.99% |
| Rayno Phantom S9-35 | 35% | 58% | >99.99% |
| Rayno Phantom S9-20 | 20% | 64% | >99.99% |
Read the two 35% rows against each other: same film VLT, 52% TSER against 58%. Six points of heat rejection separating two films that look identical on a shade card. That gap is invisible if you shop by category.

Which Tint Is Best for Perth Heat?
Choose by published TSER and the visibility you actually need, not by category. Rayno Phantom S9-50 publishes 53% TSER at 50% VLT; the far darker SunTek CIR 20 Black publishes 58% at 22%. Five points of heat for less than half the light is a poor trade for most drivers.
If you drive early, late or in rain, that visibility matters more than the five points. If the car lives outside in an uncovered car park all day, the calculation shifts. There is no single best film, only the best fit for how the car is used.
Whichever you pick, the legal limit is the finished window: factory glass and film measured together. Forward of the “B” pillar, at least 35% VLT. Behind it on a passenger car, at least 20%, and only with ADR14-compliant external mirrors on both sides. A film labelled 35% can finish well below 35% once it is on your glass, which is covered in full in our guide to the darkest legal tint in WA.
Ceramic vs carbon
Common Questions
Close enough that UV should not decide it. SunTek CIR lists more than 99% and holds the Skin Cancer Foundation Seal of Recommendation for 99%+ across 300 to 380 nm; Rayno Phantom S9 lists more than 99.99%. Both are high. Heat rejection and legal finished VLT are the real deciders.
No. Darkness is VLT; heat rejection is TSER, and they are not interchangeable. A lighter film from a strong range can reject more heat than a darker film from a weaker one. Compare TSER at the shade you are considering, then check the finished VLT is legal.
No. Ceramic and carbon are both non-metallic, so neither affects phone, GPS, radio or tyre-pressure sensors. That problem belongs to metalised film, which uses a metal layer to reflect heat.
The exact series and shade, its published TSER and UV figures, the finished VLT expected on your glass, and what the warranty covers and voids. An installer who cannot separate film VLT from the finished legal reading is the one to be careful with.
