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.
