Professional-grade PTFE film tape with silicone adhesive for friction reduction, non-stick applications, and high-temperature industrial use. Includes 6 rolls of 50mm x 33m tape with 6.7mil thickness.
3M™ PTFE Film Tape 5491 is a premium industrial adhesive tape featuring an extruded polytetrafluoroethylene (PTFE) film backing combined with a pressure-sensitive silicone adhesive. This professional-grade tape delivers an exceptionally slick, non-stick surface that provides easy clean-up and smooth material movement across a wide variety of substrates. The tape is specifically engineered to reduce friction between moving surfaces, eliminate squeaks and rattles, and minimize machinery noise in demanding industrial applications.
With dimensions of 50mm width and 33 meters length, this tape comes in a convenient 6-roll case format. The 6.7 mil thickness (0.17mm) represents an upgrade from the thinner 5490 model, offering enhanced durability and extended wear life for heavy-duty 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. The tape maintains exceptional performance across a wide temperature range from -65°F/-54°C to 500°F/260°C, making it suitable for both heated and cold-temperature environments.
This industrial tape is ideal for roll-wrap applications in web processing, high-temperature wire bundling and harnessing, lining of chutes and troughs, and mold release for composite bonding. The PTFE material provides excellent chemical resistance, enabling the tape to withstand challenging applications and serve as a temporary chemical barrier. With a silicone adhesive system that ensures clean removal from various surfaces without residue, 3M PTFE Film Tape 5491 combines superior performance with practical ease of use for industrial and occupational professionals.
