Foam PVC

[Walt Langhans]

I've read the info that putting PCV in the laser is a very bad idea, but what I came across was in reference to PVC pipe. I've recently come across PVC foam and I'm assuming that it's the same stuff they use in the pipes and it be a bad idea to laser it?

If it says PVC in it, it's bad. Tube, foam, sheet, whatever.

[Dave Sheldrake]

Dangerous to the machine and potentially fatal to the user Walt. Without extraction rated for toxics / corrosives PVC of any kind as Scotty says is a nono.

cheers

That's what I figured, thanks for the conformation.

Avoid PVC foam and go for EVA foam............

[Martin James]

When I first started taking notes on what materials worked for lasering, I wrote down a big "vinyl = NO".

Am I correct in thinking that PVC is a NO because the chloride in PVC forms chlorine gas, And

PVA, polyvinyl acetate, is OK to cut? We use PVA wood glues.

Thanks Marty

Yes - PVA is fine.
