Product Description

3M™ PTFE Extruded Film Tape 5490 and 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.
