@ -229,4 +229,23 @@ POM is most commonly used when CNCing plastic.
- Hydrophobic
- Most important because of its chemical resistance.
- Fairly expensive
- When mildly overheated, turns into horribly toxic chemicals (carbon monoxide, )
- When mildly overheated, turns into horribly toxic chemicals (carbon monoxide, hydrogen cyanide, hydrofluoric acid, even more)
# PEEK (Poly-ether Ether Ketone)
- Mechanical properties massively beyond other plastics
- Close to steel
- Twice as tough as the toughest polycarbonate
- Used in missiles and is fireproof
- $700 a kilo (at the time of writing)
- Prints at 400C
- Requires a 140C heated chamber
- Extremely high water retention
- Special bed adhesive required
- Difficult to print
# PEKK (Polyether Ketone Ketone)
Same building blocks as PEEK, in different levels
- Worse than PEEK mechanically, still far beyond other filaments
- Much easier to print compared to PEEK
# PPS (Polyphenylene Sulphide)
