3M™ PTFE Film Tape 5498 uses an extruded polytetrafluoroethylene (PTFE) film backing. This tape offers an extremely low coefficient of friction which, in combination with a pressure-sensitive rubber adhesive, creates a smooth, non-stick surface over a variety of substrates to assist in mold release applications where a non-silicone tape is required.The 3M PTFE Film Tape 5498 resists curling when unwound from the roll and lies flatter than skived PTFE film tapes, creating a more uniform non-skid surface. It is 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 5491 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.
