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 resists curling when unwound from the roll and lies flatter than skived PTFE film tapes, creating a more uniform non-skid surface. Its thicker backing extends the useful life of the tape against abrasion and wear. 3M engineers developed this high strength tape as a quick and easy solution to reduce friction between moving surfaces. It serves as an anti-stick or easy-release medium between surfaces where pressure, temperature changes and other factors may create a measure of adhesion. Applying 3M PTFE Film Tape 5490 can help improve surface movement and eliminate squeaks and rattles and reduce machine noise. PTFE is chemical resistant and can be used as a temporary chemical barrier. The tape has a wide temperature use range, from -65°F/-54°C to 500°F/260°C, making it suitable in a wide variety of functions.

What is PTFE?
Polytetrafluoroethylene (PTFE) is a synthetic material used in a variety of industries and applications to reduce the coefficient of friction. PTFE is used as a non-stick coating for frying pans and other cookware because of its non-stick property as well as high heat resistance. Its non-conductivity makes it an excellent insulating material for electrical applications. It is very non-reactive to numerous chemicals, partly due to the strength of carbon–fluorine bonds; making it very effective in containers and pipework for reactive and corrosive substances. PTFE reduces friction, wear and energy efficiency of machinery. Because of its low friction, PTFE is used in industrial applications where sliding action of parts is required, such as with bearings, gears, slide plates, etc. In these applications, it delivers significantly better performance than nylon and acetal. 3M has taken this versatile compound through an extrusion process to create a thin film, then paired the film with adhesive to make its PTFE tape. Innovative, high performance 3M PTFE tapes are reliable, durable and reduce friction.
