All Teflon is PTFE. However, not all PTFE is Teflon.
Teflon is a brand name like Kleenex. Kleenex is a brand name of tissues, but not all tissues are Kleenex.
MeganMango, welcome!
It would probably be best not to burn plastic, metal or foods.
Correct MonicaMC!!! The majority of non-stick cookware contains PTFE even though it may not be a DuPont Teflon product. Your best bet is to completely avoid all non-stick products.
For example, this high quality Calphalon does not contain Teflon but it does have PTFE. See the link please:

Finally from the T-Fal website, see answer #8 in the FAQ's:

"8 - What is T-fal non-stick made of and how safe is it?"
All non-stick coating contains PTFE which is the abbreviated name for a remarkable polymer called polytetrafluoroethylene.
The non-stick coating is not attacked by acid or alkali bases and is very stable when heated to temperatures of up to 750 deg F.
Since in a domestic kitchen the maximum temperature possible with a pan is about 570 degrees F, there is no risk should a pan be accidentally overheated.
Health authorities in France, Europe, United States and other countries have approved non-stick PTFE coatings for use on cookware because it is an inert substance which does not enter into chemical reactions with food, water or household cleaners.
If ingested it is totally innocuous in the body.
In fact, non-stick PTFE is so safe it is used by the medical profession for coating heart stimulators, coating small pipes used as replacement arteries and has even been injected into patients with serious kidney conditions.
Remember that birds respiratory system is much more sensitive than ours so regardless what they say about safe temperatures, remember that is in regards to humans health. Better safe than sorry!
