Teflon® Characteristics

Teflon® is considered to be the most slippery material that exists. It withstands extreme temperatures, is an excellent insulator and is resistant to nearly all industrial chemicals and solvents. Because it has a low coefficient of friction, it is a superb choice for applications in which materials will slide against one another and is often used for products that need an anti-stick surface.

Teflon® – a polytetrafluoroethylene – has outstanding dielectric properties that remain stable with frequency and temperature. It resists ignition and does not promote the spread of flames. Teflon® has a uniquely high bulk density.

  • Excellent thermal and electrical insulation properties
  • Low coefficient of friction
  • here to help 200FDA approved
  • Chemical resistant
  • UL94-VO flame rating

Applications for Teflon®

  • Bearings
  • Bushings
  • Gears
  • Slide plates
  • Piston rings
  • Seals
