3M PTFE film adhesive tape 5491 Grey 25 mm x 33 m 0.17 mm 7000001582

Unlike the peeled version 548/81, the extruded film is extremely smooth and suitable for finishing objects with straight surfaces. Our extruded backing resists curling when unwound from the roll and lays flatter than foamed PTFE film tapes, creating a more even, non-slip surface. We developed this tape as a quick and easy solution to reduce friction between moving surfaces. It acts as a non-stick or easy release medium where pressure, temperature changes and other factors can create a measure of adhesion. The application of 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. The tape has a wide temperature application range from 54°C to 260°C and is therefore suitable for a variety of applications. Recommended applications Roll wrapping for web processing, tapes and sheets where sticky materials and colors may occur. High temperature cable bundling and cabling Squeak and noise reduction Lining of chutes, trays and ducts Shielding and protection against chemicals Mold release for composite joints What is PTFE? Polytetrafluoroethylene (PTFE) is a synthetic material used in a variety of industries and applications to reduce the coefficient of friction. Due to its non-stick properties and high heat resistance, PTFE is used as a non-stick coating for frying pans and other cookware. Due to its non-conductivity, it is an excellent insulating material for electrical applications. PTFE is non-reactive to numerous chemicals due to the chemical resistance of fluoropolymer compounds and therefore works in containers and pipelines for reactive and corrosive substances. PTFE reduces friction, wear and energy efficiency of machines. Due to its low friction, PTFE is used in industrial applications where sliding action of parts is required, such as bearings, gears, sliding plates, etc. In these applications, it offers significantly better performance than nylon or acetal.
