ketones and alcohols.
Virgin PTFE - Chemically inert, virtually impervious. Very few chemicals are known to react chemically with
PTFE : molten alkali metals, turbulent liquid or gaseous fluorine and a few fluoro-chemicals such as chlorine
trifluoride or oxygen difluoride which readily liberate free fluorine at elevated temperatures.
