2. Polytetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polytetrafluoroethylene

   PTFE can also be reinforced where abrasion is present – for equipment processing seeded or grainy dough for example. [70] PTFE has been experimented with for electroless nickel plating. PTFE tubing is used for Bowden tubing in 3D printers because its low friction allows the extruder stepper motor to push filament through it more easily.

3. Thread seal tape - Wikipedia

   en.wikipedia.org/wiki/Thread_seal_tape

   PTFE tape used for different sized fittings PTFE tape for natural gas. There are two US standards for determining the quality of any thread seal tape. MIL-T-27730A (an obsolete military specification still commonly used in industry in the US) requires a minimum thickness of 3.5 mils and a minimum PTFE purity of 99%. [3]

4. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   Heat-shrink tubing was invented by Raychem Corporation [4] in 1962. [5] It is manufactured from a thermoplastic material such as polyolefin, fluoropolymer (such as FEP, PTFE or Kynar), PVC, neoprene, silicone elastomer or Viton. The process for making heat-shrink tubing is as follows: First the material is chosen based on its properties.

5. Tygon tubing - Wikipedia

   en.wikipedia.org/wiki/Tygon_Tubing

   Tygon Fuel and Lubricant Tubing F-4040-A is translucent yellow for positive identification and flow monitoring. It is used in small engine fuel lines, recreational vehicles, and lubrication lines. Tygon LP1100 is a low permeation EPA and CARB certified fuel line [4] also used in small engines. Tygon R-3400 UV Resistant Tubing is

6. Rulon (plastic) - Wikipedia

   en.wikipedia.org/wiki/Rulon_(plastic)

   Rulon is the trade name for a family of PTFE plastics produced by Saint-Gobain Performance Plastics. Rulon plastics are known for their low coefficient of friction, excellent abrasion resistance, wide range of operating temperatures, and chemical inertness. Common applications for Rulon include seals, piston rings, bearings, and electrical ...

7. Materials for use in vacuum - Wikipedia

   en.wikipedia.org/wiki/Materials_for_use_in_vacuum

   Polytetrafluoroethylene (PTFE or Teflon) is commonly used inside of vacuum systems. It is self-lubricating, a good electrical insulator, tolerant to fairly high temperatures, and has low out-gassing. It is not suitable for barrier between vacuum and atmosphere, as it is somewhat permeable for gases.
