2. Thread seal tape - Wikipedia

   en.wikipedia.org/wiki/Thread_seal_tape

   Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together. Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths ...

3. ETFE - Wikipedia

   en.wikipedia.org/wiki/ETFE

   ETFE is commonly used in the nuclear industry for tie or cable wraps and in the aviation and aerospace industries for wire coatings. This is because ETFE has better mechanical toughness than PTFE. In addition, ETFE exhibits a high-energy radiation resistance and can withstand moderately high temperatures for a long period.

4. Polytetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polytetrafluoroethylene

   Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]

5. Surface treatment of PTFE - Wikipedia

   en.wikipedia.org/wiki/Surface_treatment_of_PTFE

   Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.

6. Tetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Tetrafluoroethylene

   A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.

7. Fluorinated ethylene propylene - Wikipedia

   en.wikipedia.org/wiki/Fluorinated_ethylene_propylene

   Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...
