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. Polytetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polytetrafluoroethylene

   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] Polytetrafluoroethylene is a fluorocarbon solid , as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine .

4. Polymer fume fever - Wikipedia

   en.wikipedia.org/wiki/Polymer_fume_fever

   Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene (PTFE, known under the trade name Teflon) reaches temperatures of 300 °C (572 °F) to 450 °C (842 °F).

5. 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 ...

7. Triboluminescence - Wikipedia

   en.wikipedia.org/wiki/Triboluminescence

   Soviet scientists observed in 1953 that unpeeling a roll of tape in a vacuum produced X-rays. [11] The mechanism of X-ray generation was studied further in 2008. [12] [13] [14] Similar X-ray emissions have also been observed with metals. [15] Opening an envelope sealed with polymer glue may generate light that can be viewed as blue flashes in ...
