2. 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]

3. List of adhesive tapes - Wikipedia

   en.wikipedia.org/wiki/List_of_adhesive_tapes

   Invisible double-sided tape used to attach hair pieces or to hold delicate fabrics against the skin. Reflective tape High-visibility adhesive tape with retroreflective sheeting. Thread seal tape Polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. Ultra-high-molecular-weight polyethylene tape

4. 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.

5. Pressure-sensitive adhesive - Wikipedia

   en.wikipedia.org/wiki/Pressure-sensitive_adhesive

   Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).

6. Non-stick surface - Wikipedia

   en.wikipedia.org/wiki/Non-stick_surface

   The modern non-stick pans were made using a coating of Teflon (polytetrafluoroethylene or PTFE). PTFE was invented serendipitously by Roy Plunkett in 1938, [3] [4] while working for a joint venture of the DuPont company. The substance was found to have several unique properties, including very good corrosion-resistance and the lowest ...

7. 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]

8. Tape correction (surveying) - Wikipedia

   en.wikipedia.org/wiki/Tape_correction_(surveying)

   For common tape measurements, the tape used is a steel tape with coefficient of thermal expansion C equal to 0.000,011,6 units per unit length per degree Celsius change. This means that the tape changes length by 1.16 mm per 10 m tape per 10 °C change from the standard temperature of the tape.

9. Los Angeles abrasion test - Wikipedia

   en.wikipedia.org/wiki/Los_Angeles_abrasion_test

   The Los Angeles abrasion test (LA abrasion) is the North American standard for testing toughness (resistance to abrasion and degradation [1]) of construction aggregate or gravel and its suitability for road construction.
