Burning Off Teflon

Question:

PTFE coatings are often referred to by the proprietary name of Teflon, which is a trademark of the Dupont Corp. Our company manufactures burn-off ovens. One of our prospects has a requirement to burn off the Teflon from frying pans at 900-1,000° F. Will Teflon emit acids that could corrode the carbon steel oven enclosure. If so, which corrosive acid vapors will be given off? R. H.

Answer:

I have no idea what chemicals are given off when you burn Teflon. You should contact Dupont directly to obtain a MSDS sheet for the material you are trying to remove. If the MSDS sheet doesn’t help, I would talk to one of their chemists.
