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

**The repeating unit of Teflon is

-CF2-CF2-
