TEFLON® (PTFE)

Teflon® is the trade name for polytetrafluoroethylene, or PTFE. Teflon® is a registered trademark of DuPont.

PTFE is a synthetic, nontoxic, fluorocarbon-based polymer with uses in many applications. Teflon’s non-adhesive properties, along with its high resistance to chemicals, excellent electrical properties and ability to withstand a wide temperature range make it a top choice for applications such as high-temperature seals, insulators, coil separators and terminals and bearings.

 

TYPES OF TEFLON

Denver Rubber Company offers two versions of PTFE, virgin PTFE and mechanical PTFE.

Virgin PTFE Properties

As its name suggests, virgin PTFE is made from pure resin without any recycled material added.

PROPERTIES

  • Extremely chemical resistant
  • Excellent electrical insulator
  • Flexible in low temperatures.
  • FDA approved and is often used in

APPLICATIONS

  • Food and beverage
  • Pharmaceutical
  • Cosmetics

Mechanical PTFE Properties

Mechanical PTFE is made with reprocessed PTFE resin. While it has slightly lower physical properties than virgin PTFE, it’s extremely low coefficient of friction gives it excellent performance properties in a number of applications. Various fillers added during manufacturing can give mechanical PTFE enhanced performance.

PROPERTIES

  • Tolerance to extreme temperatures
  • Enhanced deformation (depending on filler)
  • Improved wear (depending on filler)
  • Low compression (depending on filler)
  • Excellent thermal properties (depending on filler)
  • Excellent electrical properties (depending on filler)

 

APPLICATIONS

  • High-performance parts
  • Non-critical chemical, mechanical, and electrical components
