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. [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]

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. Gore-Tex - Wikipedia

   en.wikipedia.org/wiki/Gore-Tex

   The most common process used to produce large sheets of ePTFE at scale is a tape stretching process through the following steps: A lubricating agent (often an oil) is added to fine PTFE powder until a paste is formed. The paste is extruded into a sheet that is calendered to obtain a specific, uniform thickness.

5. Non-stick surface - Wikipedia

   en.wikipedia.org/wiki/Non-stick_surface

   Teflon is a brand of PTFE, often used as a generic term for PTFE. The metallic substrate is roughened by abrasive blasting, then sometimes electric-arc sprayed with stainless steel. [8] [9] The irregular surface promotes adhesion of the PTFE and also resists abrasion of the PTFE. [10] Then one to seven layers of PTFE are sprayed or rolled on.

6. Spectralon - Wikipedia

   en.wikipedia.org/wiki/Spectralon

   The material consists of PTFE powder that has been compressed into solid forms and sintered for stability, with approximately 40 percent void volume [clarification needed] to enhance scattering of light. [6] Surface or subsurface contamination may lower the reflectance at the extreme upper and lower ends of the spectral range.

7. 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 ...
