5490
PTFE Extruded Film Tape
5490 is a 3.5 mil. extruded PTFE (polytetrafluorethylene) film backing with a silicone adhesive primarily used for an easy release surface on rollers, plates, belts, etc. where build up of sticky materials and inks can occur. Tape 5490 and 5491 are extruded, calendered film tapes that provide an exceptionally smooth surface when applied and resist curling during unwind. Extruded PTFE film tapes lie flatter than typical skived PTFE film tapes. Chemical resistance of tape 5490 and 5491 is excellent except to organic solvents.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
