Basics
- An abrreviation for Polytetrafluoroethylene
- Sold Under the Brand Name Teflon
- An Engineering Plastic
- A Floropolymer that is highly chemical resistant, and has low friction
- Hard to work with, but it can be SLA Printed or Chemically coated on materials
- Useful for chemistry equipment, medical equipment, nonstick coatings, and low friction componets
Safety
- TLDR: Not the WORST (ie on a scale from Deionized Water to Dimethyl Mercury / or Sulfur Mustards (ie critical to life + benign TO toxic and no real use) it's probably a 4) but not the best and tied to some VERY NASTY related/required chemicals so best to avoid it if possible ( Reduce / Substitution / Precautionary Principle etc)
- Also special note that as with the Canary in the Coal Mine , at high temperatures "Teflon Coated" / Nonstick Pans release some "nasties" that aren't bad enough for humans (at least in the Acute sense), but ARE lethal to Birds and such, so be careful about that
- For a pretty good communication of the state of current understanding, the videos (linked under this page's external links section) by Veritassium (YouTube Channel) and [[
