Coated Cordura 1000D Nylon?

For the life of me, I can’t find any info on what exactly the “coating” is made of. I don’t want to ruin my new laser. I know the Cordura is nylon, but what is the coating? I’ve read comments about it being plastic (bad), urethane (?) and polyurethane (?)… anyone have an MSDS on it?

Their web site says the coating is Polyurethane.

I’d be more concerned about whether or not the nylon contains chlorine. You could test that by burning a small piece on a copper wire. If you get a green flame do not put it in the laser.

Laser processing of nylon can be performed with a 9.3 or 10.6 micron CO2 laser . Nylon does not readily absorb the energy from the 1.06 micron fiber laser and is not recommended for this material. Laser cutting of nylon with a CO2 laser produces a clean edge with minimal melting along the cut path.

This gave me hope. I’ve seen similar advice elsewhere.

Just be careful and test a piece. The name nylon can describe many different components. If it contains chlorine it is a no go for laser.

Polyurethane does not contain any halogens. So as long as your glowforge is well ventilated you won’t be damaging your glowforge.

Im definitely going to do the copper wire melt test from the post above. But it looks as if everything SHOULD be okay! I’m very well ventilated. I just cannot afford to damage my GF. My (very)small business relies on it heavily lol… so… can’t injure the MVP! lol

Exactly. I agree it is probably not going to be an issue.
You may not injure your lungs because the fan will draw the fumes away however if there is chlorine gas released it will damage your GF very quickly.
Better safe than sorry.

That is a good thing to know about…
