2. Polytetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polytetrafluoroethylene

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

3. 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.

4. 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.

5. ECTFE - Wikipedia

   en.wikipedia.org/wiki/ECTFE

   In lining or coating applications using ECTFE, permeability of certain small molecules determines the lifetime of anti-corrosion protection. Small molecules such as H 2 O , O 2 , Cl 2 , H 2 S , HCl , HF , HBr , N 2 , H 2 , and CH 3 OH are relatively mobile in the polymer matrix and lead to measurable effects.

6. Fibre-reinforced plastic tanks and vessels - Wikipedia

   en.wikipedia.org/wiki/Fibre-reinforced_plastic...

   PP, PVC, PTFE, ECTFE, ETFE, FEP, CPVC, PVDF are used as common thermoplastic liners. Due to FRP's weakness to buckling, but immense strength against tensile forces and its resistance to corrosion, a hydrostatic tank is a logical application for the composite.

7. Fluoropolymer - Wikipedia

   en.wikipedia.org/wiki/Fluoropolymer

   Tests showed the substance was resistant to corrosion from most acids, bases and solvents and had better high temperature stability than any other plastic. By early 1941, a crash program was making substantial quantities of PTFE for the Manhattan Project. [1] [2] [3] [4]
