<VV> A/C For 69 Corvair

[jvhroberts at aol.com]

 Well, er, ah, not really. HFCs, although they contain fluorine, which is an oxidizer, has already 'spent' that energy by bonding to the carbon atoms in the molecule. Viton is a way different beast.

John is correct, is does not burn, in the normal sense. Under some circumstances 

it becomes the oxidizer. As some may know I test (among other things) for the 

burning rate of gun and rocket propellants, pyrotechincs, and other explosives. 

One of the mixtures i have tested used Viton as the oxidiser, so any oter HFC 

could be even better.

compressor, like in your fridge or window air conditioner. And, unlike propane, 

it doesn't burn! AT ALL!
