2. Red plague (corrosion) - Wikipedia

   en.wikipedia.org/wiki/Red_plague_(corrosion)

   More details can be seen in ESA document PSS-01-720, [2] with details on determining the susceptibility of silver-plated copper wire to red plague corrosion found in ECSS-Q-ST-70-20C. [ 3 ] It is not to be confused with purple plague , a type of galvanic corrosion that occurs between gold and aluminum.

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. Jewelry wire - Wikipedia

   en.wikipedia.org/wiki/Jewelry_wire

   Jewelry wire is wire, usually copper, brass, nickel, aluminium, silver, or gold, used in jewelry making. Wire is defined today as a single, usually cylindrical, elongated strand of drawn metal. However, when wire was first invented over 2,000 years BC, it was made from gold nuggets pounded into flat sheets, which were then cut into strips. The ...

5. Thread seal tape - Wikipedia

   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]

   NEC 2008 400.22(f) allows surface marking with ridged, grooves or white stripes on the surface of lamp cord. With transparent cord the hot wire is copper colored, and the neutral is silver colored. Grounding wire of circuit may be bare or identified insulated wire of green or green having yellow stripes. All metallic systems in a building are ...

7. PTFE fiber - Wikipedia

   en.wikipedia.org/wiki/PTFE_fiber

   PTFE fiber is a chemically resistant material. It is used in woven form in certain pump packings [1] as well as in nonwoven form in hot gas bag filters for industries with corrosive exhausts. [2] [3] Because PTFE is relatively insoluble and has a very high melting point, PTFE fibers can not be fashioned from conventional melt or solution ...
