3M™ PTFE Film Tape 5490 uses an extruded polytetrafluoroethylene (PTFE) film backing. This tape 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 materials in many types of lay-flat applications. The extruded film backing on 3M™ PTFE Film Tape 5490 resists curling when unwound from the roll and lies flatter than skived PTFE film tapes, creating a more uniform non-skid surface. We developed this tape as a quick and easy solution to reduce friction between moving surfaces. It functions as an anti-stick or easy-release medium where pressure, temperature changes, and other factors may create a measure of adhesion. Applying 3M™ PTFE Film Tape 5490 can help improve surface movement, eliminate squeaks and rattles, and reduce machine noise. PTFE is chemical resistant and can be used as a temporary chemical barrier. Dispensable and appropriate for outdoor use.
