Industrial-grade PTFE film tape with silicone adhesive for friction reduction, non-stick applications, and high-temperature performance from -65°F to 500°F. Features extruded film backing, excellent chemical resistance, and superior durability. 6 rolls per case.
3M™ PTFE Film Tape 5491 is an industrial-grade adhesive tape featuring extruded polytetrafluoroethylene (PTFE) film backing with pressure-sensitive silicone adhesive. This premium tape delivers an exceptionally slick, non-stick surface that significantly reduces friction between moving surfaces, making it ideal for complex manufacturing and industrial applications. The tape's unique properties enable it to function as an anti-stick or easy-release medium in environments where pressure, temperature changes, and other factors may create adhesion challenges.
Designed for high-performance applications, 3M™ PTFE Film Tape 5491 features superior durability and longevity compared to its predecessor model 5490. The extruded film backing resists curling when unwound and lies flatter than traditional skived PTFE film tapes, creating a more uniform non-skid surface. This tape excels in reducing squeaks, rattles, and machinery noise while providing excellent chemical resistance. With an impressive temperature range from -65°F to 500°F (-54°C to 260°C), this tape maintains consistent performance across diverse industrial environments and heated machinery applications.
The 3M™ PTFE Film Tape 5491 is specifically engineered for industrial and occupational use, offering reliable performance in roll-wrap applications, web processing, high-temperature wire bundling, mold release for composite bonding, and chemical shielding applications. Each case contains 6 rolls of 3/4 inch width by 36 yards length, with a total tape thickness of 6.7 mils, providing substantial coverage for demanding industrial operations. This tape is not intended for consumer use and must be selected and used in compliance with applicable health and safety regulations.
