2. Fluorinated ethylene propylene - Wikipedia

   en.wikipedia.org/wiki/Fluorinated_ethylene_propylene

   Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...

3. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   Heat-shrink tubing was invented by Raychem Corporation [4] in 1962. [5] It is manufactured from a thermoplastic material such as polyolefin, fluoropolymer (such as FEP, PTFE or Kynar), PVC, neoprene, silicone elastomer or Viton. The process for making heat-shrink tubing is as follows: First the material is chosen based on its properties.

4. Fluoropolymer - Wikipedia

   en.wikipedia.org/wiki/Fluoropolymer

   In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a ...

5. Perfluoroalkoxy alkane - Wikipedia

   en.wikipedia.org/wiki/Perfluoroalkoxy_alkane

   Similarly enhanced processing properties are found in fluorinated ethylene propylene (FEP), the copolymer of tetrafluoroethylene and hexafluoropropylene. [5] However FEP is ten times less capable of withstanding repeated bending without fracture than PFA. [1] Perfluoroalkoxy alkane is used to fabricate tubes to handle aggressive chemicals.

6. Polytetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polytetrafluoroethylene

   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] Polytetrafluoroethylene is a fluorocarbon solid , as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine .

7. ETFE - Wikipedia

   en.wikipedia.org/wiki/ETFE

   Useful comparison tables of PTFE against FEP, PFA and ETFE can be found on Chemours' website, listing the mechanical, thermal, chemical and electrical properties of each, side by side. [1] ETFE is effectively the high-strength version of the other three in this group. ETFE film is self-cleaning (due to its nonstick properties) and recyclable. [2]
