Description & Characteristics Perfluoroperhydrofluorene,C13F22, is a fully-fluorinated, odourless, colourless, non-volatile liquid with the following characteristics: Compatibility with most construction materials Excellent chemical and thermal stability Non flammability Practically non-toxic1 Applications Perfluoroperhydrofluorene finds many applications as a fluid for use in the electronics industries, including vapour phase soldering, condensation inert heating, fluid for testing and direct contact cooling. Safety, Handling and Storage Although Perfluoroperhydrofluorene is considered biologically and chemically inert, good laboratory practice should be observed when handling. Perfluoroperhydrofluorene has an indefinite shelf life if properly stored in its original sealed container. Safety data sheets are available on request.
