Premium industrial PTFE film tape with silicone adhesive, 14 in × 72 yd, 6.7 mil thickness. Non-stick surface, low friction, wide temperature range (-65°F to 500°F), excellent chemical resistance, ideal for machinery, web processing, and noise reduction.
The 3M™ PTFE Film Tape 5491 is a premium industrial adhesive tape engineered for applications requiring exceptional non-stick properties and low friction performance. This brown tape features an extruded polytetrafluoroethylene (PTFE) film backing combined with a pressure-sensitive silicone adhesive, creating an exceptionally slick surface that provides easy clean-up and clean removal from a variety of surfaces. The tape measures 14 inches in width and 72 yards in length with a total thickness of 6.7 mil, making it ideal for industrial applications where durability and consistent performance are critical.
Designed as a thicker, more durable version of the 3M™ PTFE Film Tape 5490, this tape offers superior protection and extended wear life. The extruded PTFE film backing lies flatter than typical skived PTFE film tapes, creating a more uniform non-stick surface and resisting curling when unwound from the roll. With excellent chemical resistance and a wide temperature range from -65°F/-54°C to 500°F/260°C, this tape is suitable for diverse industrial environments including heated machinery, equipment, and challenging chemical applications.
This tape is specifically engineered to reduce friction between moving surfaces, eliminate squeaks and rattles, and reduce machine noise in lay-flat applications. It functions as an anti-stick or easy-release medium where pressure, temperature changes, and other factors may create adhesion. Common applications include roll-wrap for web processing, high-temperature wire bundling, squeak and noise reduction, lining of chutes and troughs, chemical shielding, and mold release for composite bonding. The product comes in 1 roll per case and is intended for industrial and occupational use only.
