   en.wikipedia.org/wiki/Harwin_Drive

   Harwin Drive (好运大道 Hǎoyùn Dàdào) Harwin Drive is a road in Houston, Texas. The Greater Houston Convention and Visitors Bureau identifies the section between Interstate 69/U.S. Route 59 (Southwest Freeway) and Beltway 8 as being a shopping district. [1] Harwin has many strip malls with discount shops and wholesale warehouses.

3. 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]

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. 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 ...

6. Nafion - Wikipedia

   en.wikipedia.org/wiki/Nafion

   Nafion is a brand name for a sulfonated tetrafluoroethylene based fluoropolymer-copolymer synthesized in 1962 by Dr. Donald J. Connolly at the DuPont Experimental Station in Wilmington Delaware (U.S. Patent 3,282,875). Additional work on the polymer family was performed in the late 1960s by Dr. Walther Grot of DuPont. [1]

7. Polychlorotrifluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polychlorotrifluoroethylene

   PTFE has a higher melting point and is more crystalline than PCTFE, but the latter is stronger and stiffer. Though PCTFE has excellent chemical resistance, it is still less than that of PTFE. [22] PCTFE has lower viscosity, higher tensile strength and creep resistance than PTFE. [1] PCTFE is injection-moldable and extrudable, whereas PTFE is ...
