Premium extruded PTFE film tape with silicone adhesive for friction reduction, noise elimination, and non-stick applications on machinery. Wide temperature range -65°F to 500°F. Case of 14 rolls, 1/2 inch x 36 yard each.
3M™ PTFE Film Tape 5491 is a premium industrial-grade adhesive tape featuring an extruded polytetrafluoroethylene (PTFE) film backing combined with a pressure-sensitive silicone adhesive. This high-performance tape delivers an exceptionally slick, non-stick surface that provides easy clean-up and superior release properties across a wide variety of substrates. The tape is specifically engineered to reduce friction between moving surfaces, making it ideal for applications requiring smooth material movement and noise reduction in industrial machinery and equipment.
The 6.7 mil thickness makes this tape a more durable version compared to the 3M PTFE Film Tape 5490, offering extended wear life and improved performance in demanding applications. The extruded PTFE film backing resists curling when unwound from the roll and lies significantly flatter than typical skived PTFE film tapes, creating a more uniform non-skid surface. This characteristic ensures consistent performance and easier application in lay-flat configurations. The tape's wide temperature range from -65°F to 500°F (-54°C to 260°C) makes it suitable for use on heated machinery, equipment, and high-temperature processing environments.
With excellent chemical resistance, high strength, and superior abrasion resistance, this tape effectively reduces machinery noise, eliminates squeaks and rattles, and minimizes friction-related wear. The silicone adhesive provides clean removal from various surfaces without leaving residue. Each case contains 14 rolls of brown PTFE film tape, with each roll measuring 1/2 inch wide by 36 yards long, making it an economical solution for industrial facilities, manufacturing operations, and maintenance departments requiring reliable non-stick tape solutions.
