Industrial-grade PTFE film tape with silicone adhesive for friction reduction, 14 in × 36 yd, 6.7 mil thickness, -65°F to 500°F operating range
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 6.7 mil thick tape measures 14 inches wide by 36 yards long and comes in a convenient single roll per case format. The tape delivers an exceptionally slick, non-stick surface that provides superior performance in friction reduction applications. The extruded PTFE film backing resists curling when unwound and lies flatter than traditional skived PTFE film tapes, creating a more uniform non-skid surface ideal for lay-flat applications.
Designed for industrial and occupational use, this tape excels in reducing friction between moving surfaces and eliminating squeaks and rattles in machinery. The silicone adhesive ensures clean removal from a variety of surfaces without leaving residue. With excellent chemical resistance and a wide temperature operating range from -65°F (-54°C) to 500°F (260°C), the tape performs reliably on heated machinery and equipment. The 5 mil backing thickness combined with the total 6.7 mil tape thickness provides enhanced durability and longer wear compared to thinner alternatives, making it ideal for demanding industrial applications.
This versatile tape is recommended for roll-wrap applications in web processing, high-temperature wire bundling and harnessing, squeak and noise reduction, lining of chutes and troughs, chemical shielding, and mold release for composite bonding. The tape's low coefficient of friction, combined with its pressure-sensitive silicone adhesive, creates a smooth surface that assists in material movement and reduces friction, wear, and energy consumption in machinery. With an 18-month shelf life and sold as a complete roll unit, 3M™ PTFE Film Tape 5491 is the ideal solution for industrial friction reduction and surface protection needs.
