What is Teflon???

• Is a high performance fluoropolymer coatings used
  for low friction (dry lubrication), wear
  resistance, heat and chemical resistance,
  corrosion resistance, abrasion resistance,
  electrical insulation, non-wetting, cryogenic
  stability, FDA compliance and non-stick
  applications.
