Polyterafluoroethylene (Teflon)

[rainbow line]

Polytertrafluroethylene, or Teflon, is a linear polymer like polyethlene, the only difference being that instead of hydrogen atoms there are fluorine atoms.

Properties of Teflon:

  • Very high crystallinity as manufactured about 90 percent
  • Insoluble in most solvents
  • Uniquely nonadhesive
  • Low friction properties
  • Constant electrical and mechanical properties from 20 to about 250 degrees Celsius
  • High impact strength

    Teflon is typically used as:

  • Coating for frying pans
  • for wiers
  • Cable insulation
  • Insulation for motors and generators
