2. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   PTFE (fluoropolymer) tubes have a wide operating temperature range (-55 to 175 °C), a low coefficient of friction, and high resistance to chemicals and punctures. [ 7 ] Viton , another fluoropolymer with high chemical resistance, is widely used in hydraulic equipment.

3. Materials for use in vacuum - Wikipedia

   en.wikipedia.org/wiki/Materials_for_use_in_vacuum

   Tungsten is often used in high temperature applications as well as for filaments in electron/ion optics. It becomes brittle from work hardening when mechanically deformed, or subjected to very high temperatures. Molybdenum and tantalum are useful for high temperature applications. [3] Titanium and niobium are good materials.

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. Heated hose - Wikipedia

   en.wikipedia.org/wiki/Heated_hose

   Heated hose assembly. Heated hoses are hoses used for transporting liquids or molten materials where integral heat is needed for temperature control. Heated hoses are used in bonding technology, filling and dosing systems, medical technology, chemical, pharmaceutical and food industry, extruder applications, and research & development.

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. 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]

8. 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 ...

9. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as ...
