The military uses the common plastic Teflon (polytetrafluoroethylene) as an oxidizer in place of potassium perchlorate in incindiary flash powders (60% Teflon - 40% Al or Mg). It's quite perculiar, since it's fluorine and not oxygen that does the oxidizing.
This means good news for pyros! It solves the problem of obtaining/making our chlorates. All we have to do is buy some Teflon, and powder it. Well, there's the hard part. How do guys suggest we go about powdering a hardy plastic like Teflon? Any ideas?

Melt it in a block shape since it is thermoplastic and powder it with sandpaper!

NBK once said that Teflon's fumes would probably kill a man, this opens up dangers in the powdering of the product, a coffee grinder would be dangerous.
Flourine reacts with pretty much every organic substance, I guess the generating of flourine causes a reaction with the metal creating an exothermic reaction.

It would take more than the heat of a fuse to start the reaction if this is true.

Is there any reading on this?

Teflon is inert towards nearly anything (ESPECIALLY ACIDS, BASES,...) it enters even in the artificial blood made from PFE polyfluoroethylene and that has a big contain of O2...it is a white blood that you have seen in the movie ABYSS...a liquid to breath in (it can also be injected!).
Polyhalocarbons are provent to react/detonate upon shock/detonator when Al powder or Na is suspended in it!
CCl4 + Al --> AlCl3 + C +Cl2 + a lot of heat!
Here the idea is the same:
CF2=CF2 + Al --> AlF3 + C +F2 + even more heat

Hey,codemason-Firefox sell's PTFE powder;it's $15.00 for 8 ounces.
Oh,Pyrotek has it,too ($8.95 per lb.).

Powdered polytetrafluoroethylene can only cause some skin or eye irritation. It is used in magnetic stirrers as it is very inert. Halogens can cause a reaction.

For what purpose is Teflon used for/how do I know that it is teflon? Few months ago I came across some site where this dude swore that if you mix toothpaste containing KNO3 and powdered CD's and some catalyst, then you get shock-sensitive xplosive, that releases flourine as well. When I read that I labled it as pure crap, since kno3 is never used to make HE. The way author explained this nonesense was that KNO3 oxidizes plastic, which I thought was rediculous. But the "symptoms" were similar to this thread's so I thought I'll bring it up.

Coffe-grinder probably wouldn't handle teflon, since it's too soft. Is it worth to try grind some on grater and mix with Al (paint grade). Maby lighting with KClO3/sugar.
In which form do they use teflon in abovenamed military comp, size of particles? Google seems to give lots of results, but not useful ones..

Desmikes, you sure you weren't reading the "Anti-Phorum"? ;)

Some toothpastes for sensitive teeth contain Strontium or Potassium Nitrates, however, this is usually around 10-20%. The guy probably lit the stuff and it burned with a slight fizzle. Being a 12 year old kewl fuckpiece, he called it a powerful exotic thermite.
