Title: Polytetrafluoroethylene


1
Polytetrafluoroethylene
  • (Teflon)

2
Background Information
  • Teflon is a synthetic fluoropolymer of
    tetrafluoroethylene
  • It is the non-stick coating on your frying pans
  • It is used as lubricants in machinery
  • Powdered Teflon is used as an oxidizer in
    pyrotechnics
  • Teflon in put in sportswear to reduce
    friction-induced blisters

3
History
  • Polytetrafluoroethylene was accidentally
    discovered in 1983 by Roy Plunkett. Roy was
    attempting to make a new chlorofluorocarbon
    refrigerant for Kinetic Chemicals during the
    process, there was a weight problem and upon
    investigation, he found a white, waxy material
    which was quite slippery. Further analysis showed
    that it was polymerized perfluoroethylene. This
    new material was patented by Kinetic Chemicals in
    1941 and the Teflon trademark was registered in
    1945.

Risks
  • Over-heated pans can release fumes which will
    cause flu-like symptoms for a little while.
  • Perfluorooctanoic Acid or PFOA (a by-product of
    Teflon) has shown the potential to develop tumors
    in animal studies.
  • Human studies with PFOA have shown slightly
    similar results with tumors, but much less so.
  • This in NO WAY means that you will grow a tumor
    from frying your eggs on a Teflon pan.

5
Benefits
  • The benefits of Polytetrafluoroethylene lie in
    the many products that it can be made with. There
    aren't any medical or health other than lubricant
    in tools.

6
Alternate Solutions
  • Not enough is known about the effects of Teflon
    and PFOA due to them being minimal. We dont
    really have an alternate action or material.
