Topic: Extruding PVA?

Has anyone had any luck with this? I remember hearing that PVA supposedly decomposes into some nasty stuff when it gets too hot, so obviously that could be problematic.

Where'd you see that avoid thermal decomposition? Here's the MSDS for Esun PVA:

I have a writeup someone sent me on their PVA success, if you're interested I can upload it. As usual, a big key is pre drying the polymer.

I don't remember, I could be remembering incorrectly. Anyway, if you could upload that writeup, that would be awesome!
