Industrial-grade PTFE film tape with silicone adhesive for friction reduction, non-stick applications, and temperature-resistant performance from -65°F to 500°F.
3M™ PTFE Film Tape 5491 is a premium industrial adhesive tape featuring an extruded polytetrafluoroethylene (PTFE) film backing with silicone adhesive. This specialized tape offers an exceptionally slick, non-stick surface that provides easy clean-up and reduces friction between moving surfaces. The tape measures 10 inches wide by 36 yards long with a total thickness of 6.7 mil, making it ideal for high-performance applications requiring durability and reliable performance.
The tape's extruded PTFE film backing resists curling when unwound and lies flatter than typical skived PTFE film tapes, creating a more uniform non-skid surface. With an extremely low coefficient of friction combined with pressure-sensitive silicone adhesive, this tape functions as an anti-stick or easy-release medium in applications where pressure, temperature changes, and other factors may create adhesion. The silicone adhesive ensures clean removal from a variety of surfaces without leaving residue.
Designed for industrial and occupational use, 3M PTFE Film Tape 5491 operates across a wide temperature range from -65°F (-54°C) to 500°F (260°C), making it suitable for heated machinery and equipment. The tape demonstrates excellent chemical resistance and high strength with abrasion resistance, enabling it to withstand challenging applications including web processing, high-temperature wire bundling, noise reduction, and mold release applications. Each case contains 1 roll and is intended for trained industrial customers only.
