polyester - Laser Safe?

[Pete Simmons]

Did a quick search but will ask again

is thermo set polyester as used in a plastic gun grip safe to laser?

[Joe Pelonio]

It should be but you really have to look at the MSDS for that manufacturer to be sure. I checked one for Crane Composites and it has fiberglass reinforcement added, but should still be fine.

Polyester is fine...

[Mark Winlund]

Polyester (mylar and other trade names) are one of the safer materials to use. Downside is they won't stretch like vinyls. The metallic engravable material usually has a polyester base.
