- 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
- Thicker version of 3M™ PTFE Film Tape 5490, providing more durability and longer wear
- Extruded 3M™ PTFE Film Tape lies flatter than typical skived PTFE film tapes
- Excellent chemical resistance enables tape to withstand challenging applications
- High strength and abrasion resistance ensures reliability and performance to reduce friction, rattle and machinery noise
Our 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.
Reduce Friction Between Moving Surfaces
Our extruded film backing resists curling when unwound from the roll and lies flatter than skived PTFE film tapes, creating a more uniform non-skid surface. We developed this tape as 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 (PDF, 171.26 Kb) 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. The tape has a wide temperature use range, from -65°F/-54°C to 500°F/260°C, making it a suitable choice for a variety of applications.
