High temp materials that are CO2 cuttable

[Harper Abbot]

I'm looking for ideas for high temp (say, maybe 350F) materials that are cuttable with a mid-wattage CO2 laser. Any ideas? The perfect candidate will be thin, rigid, and cheapish.

Purpose for material would help narrow it down. Silicone sheet is high-temp and easily cut, but not ridgid. Wood is ridgid and handles that high of a temp if you don't mind a little browning over time.

this will be a decorative piece that will be subjected to high-ish wattage incandescent at close distance within a cabinet.

How close? Any air vents? Colors? How high of wattage?

mica sheet if very thin. .020" or less. It's semi-transparent though and may need a high temp paint layer. Also pricey and very brittle.

Not sure if polycarbonate would be OK at 350, but if you don't mind the mess of cutting it, it may work for you.

PC won't take 350 very long. We vac form it at around 360.

Is that safe for a cabinet? Any reason the have to use incandescent?


I'd really consider changing it to CFL, then you could use acrylic.

Any of the traffolytes or phenolic resin based engravers material will work (traffolyte is the brand name here - not sure what its called in US) , That brown phenolic resin impregnted material stuff will work too , so would card - paper burns at 451 (Farenheit 451)
I think borax is used to make wood or paper fireproof - you could soak the card in borax?
