Why is PTFE resistant to Acrylonitrile?

PTFE shows excellent resistance to Acrylonitrile due to the extremely strong carbon-fluorine bonds making it virtually inert to almost all chemicals.

⚠️ When NOT to use PTFE

Avoid using PTFE (Teflon) with molten alkali metals, fluorine gas at high temperatures, and certain fluorinated compounds. It is the most chemically resistant plastic available.
