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. 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.
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
