PTFE is essentially chemically inert and is highly resistant to chemical attack up to its 500º F. maximum continuous operating temperature. As indicated in the referenced PTFE Handbook above, there are a few exceptions including molten alkali metals, turbulent liquid, or gaseous fluorine; and a few fluorochemicals, such as chlorine trifluoride, ClF3, or oxygen difluoride, OF2, which readily liberate free fluorine at elevated temperatures.  Several tables are available on the web supporting appropriate usage of PTFE with chemicals and various concentrations and temperatures. 

We have a set of strict quality testing system, never expected finished products, will be tested and registered, traceable
