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]

Fluorinated polymers like PTFE and PVDF are especially thermally stable due to strong carbon-fluorine (C–F) bonds, the strongest in organic chemistry, which contribute to the durability of these materials under heat. PVDF is semi-crystalline, giving it a balance of rigidity and flexibility across temperatures from −35 °C to 160 °C.

OLE 1.0, released in 1990, was an evolution of the original Dynamic Data Exchange (DDE) concept that Microsoft developed for earlier versions of Windows.While DDE was limited to transferring limited amounts of data between two running applications, OLE was capable of maintaining active links between two documents or even embedding one type of document within another.
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.
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 ...
Polytetrafluoroethylene (PTFE), sometimes called by its DuPont name Teflon, [203] represents 60–80% by mass of the world's fluoropolymer production. [201] The largest application is in electrical insulation since PTFE is an excellent dielectric. It is also used in the chemical industry where corrosion resistance is needed, in coating pipes ...
