3M PTFE Extruded Film Tape 5491
3M™ PTFE Extruded Film Tape 5491 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 web
materials in many types of roll-wrap lay flat applications .
Features :
- Extruded PTFE film tapes lie flatter than typical skived PTFE film tapes, resists
curling during unwind and provide an exceptionally smooth surface when applied.
- Non-stick PTFE film provides an exceptionally slick surface for easy clean-up.
- Thicker backing helps extend the service life, compared to thinner versions, when
subjected to abrasion or wear.
- Provides excellent chemical resistance except to organic solvents. Note: The
silicone adhesive will be attacked by commercial organic solvents and so are not
recommended for application requiring organic resistance.
- Silicone adhesive provides clean removal from a variety of surfaces.
Applications :
- Easy-release surface by wrapping rollers, plates, belts, etc. where build-up of
sticky materials and inks can occur, minimizing clean-up.
- Chemical resistant surface for sealing and masking.
- Low coefficient of friction surface on rollers, formers, etc. to facilitate web
movement.
- High strength and abrasion resistance reduce friction between surfaces, minimizing
rattle and machinery noise.
- Mold release for composite or metal bonding.
- Wide temperature range for performance on or near heated machinery and
equipment.
