Premium 3M PTFE film tape with silicone adhesive for non-stick, low-friction industrial applications. Brown, 4 in × 36 yd, 6.7 mil thickness. Temperature range -65°F to 500°F. 3 rolls per case.
3M™ PTFE Film Tape 5491 is a premium industrial adhesive tape featuring an extruded polytetrafluoroethylene (PTFE) film backing with pressure-sensitive silicone adhesive. This exceptional tape delivers an extremely low coefficient of friction, making it ideal for applications requiring non-stick surfaces and easy release properties. The brown-colored tape measures 4 inches wide by 36 yards long with a total thickness of 6.7 mil, providing durability and consistent performance across demanding industrial environments.
Designed for lay-flat applications, the extruded PTFE film backing resists curling when unwound from the roll and lies flatter than typical skived PTFE film tapes, creating a more uniform non-stick surface. The combination of PTFE's non-stick properties and 3M's pressure-sensitive silicone adhesive creates a smooth, non-stick surface that functions effectively as an anti-stick or easy-release medium. This tape excels in reducing friction between moving surfaces, eliminating squeaks and rattles, and reducing machinery noise while maintaining excellent chemical resistance.
With a wide temperature operating range from -65°F (-54°C) to 500°F (260°C), this tape is suitable for high-temperature applications and heated machinery. The case contains 3 rolls, making it economical for industrial and occupational use. Ideal applications include roll-wrap for web processing, high-temperature wire bundling, noise reduction, lining of chutes and troughs, chemical shielding, and mold release for composite bonding. This product is specifically designed for industrial and occupational use only and is not intended for consumer sale or use.
