PTFE (R) Products from American Seal & Packing

PTFE or Polytetrafluoroethylene, is a linear polymer like polyethylene, the only difference being that instead of hydrogen atoms there are fluorine atoms. It has a very high crystallinity as manufactured - about 90 percent. PTFE is insoluble in most solvents, uniquely nonadhesive, and has low friction properties. PTFE has constant electrical and mechanical properties from 20 to about 250 degrees Celsius, and it has high impact strength. PTFE is typically used as coatings for frying pans, for wire and cable insulation, and insulation for motors and generators.

The repeating unit of PTFE® is -CF2-CF2- and the structure of PTFE®: PTFE (R) Chain
