Polytetrafluoroethylene (PTFE) sheet is a soft engineering plastic with many unique properties: 

  • Non-stick: PTFE has a low coefficient of friction, making it ideal for non-stick coatings for cookware 
  • Thermal stability: PTFE is one of the most thermally stable plastics 
  • Chemical resistance: PTFE is resistant to most known elements and compounds 
  • Electrical properties: PTFE has excellent dielectric properties and is used in printed circuit boards 
  • Food approved: PTFE is food approved and resistant to UV 

PTFE is also known by its trade name, Teflon. It has many industrial applications, including: 

  • Gaskets, linings, or bushings: PTFE can contain aggressive chemicals 
  • Slide plates or bearings: PTFE can be used in low friction applications 
  • Electrical products: PTFE can be used in coaxial cables, hookup wires, and printed circuit boards 
  • Screen printing equipment: PTFE can prevent the buildup of adhesives and dried ink 

PTFE is subject to creep and is not suitable for use with highly abrasive materials.
