Details
  • Non-stick PTFE film provides an exceptionally slick surface for easy clean-up
  • Silicone adhesive provides clean removal from a variety of surfaces
  • Wide temperature range for performance on heated machinery and equipment
  • Extruded PTFE film tapes lie flatter than typical skived PTFE film tapes, resists curling during unwind and provide an exceptionally smooth surface when applied.
  • Extruded 3M™ PTFE Film Tape lies flatter than typical skived PTFE film tapes
  • Excellent chemical resistance enables tape to withstand challenging applications
  • Waterproof and easily removable

3M™ PTFE Film Tape 5491 uses an extruded polytetrafluoroethylene (PTFE) film backing. This tape offers an extremely low coefficient of friction which, in combination with a pressure-sensitive silicone adhesive, creates a smooth, non-stick surface over a variety of substrates to assist in the movement of materials in many types of lay-flat applications.

The 3M™ PTFE Film Tape resists curling when unwound from the roll and lies flatter than skived PTFE film tapes, creating a more uniform non-skid surface. It is a quick and easy solution to reduce friction between moving surfaces. It functions as an anti-stick or easy-release medium where pressure, temperature changes, and other factors may create a measure of adhesion. Applying 3M™ PTFE Film Tape 5491 can help improve surface movement, eliminate squeaks and rattles, and reduce machine noise. PTFE is chemical resistant and can be used as a temporary chemical barrier. Dispensable and appropriate for outdoor use.

Suggested Applications

  • Roll-wrap for web processing, belts and plates where sticky materials and inks may occur
  • High temperature wire bundling and harnessing
  • Squeak and noise reduction
  • Lining of chutes, troughs and ducts
  • Shielding and protecting against chemicals
  • Mold release for composite bonding
