Premium industrial PTFE film tape with silicone adhesive, non-stick surface, wide temperature range -65°F to 500°F, ideal for friction reduction and noise elimination in machinery applications.
3M™ PTFE Film Tape 5491 is a premium industrial-grade adhesive tape featuring an extruded polytetrafluoroethylene (PTFE) film backing with silicone pressure-sensitive adhesive. This specialized tape delivers an exceptionally low coefficient of friction combined with non-stick properties, making it ideal for applications requiring easy release and smooth material movement. The tape measures 1 inch in width, 36 yards in length, with a total thickness of 6.7 mil, and comes in a case of 9 rolls.
Designed for high-performance industrial applications, this PTFE tape excels at reducing friction between moving surfaces, eliminating squeaks and rattles, and minimizing machinery noise. The extruded PTFE film backing resists curling when unwound and lies flatter than traditional skived PTFE film tapes, creating a more uniform non-stick surface. With excellent chemical resistance and a wide operating temperature range from -65°F to 500°F (-54°C to 260°C), this tape is suitable for web processing, high-temperature wire bundling, composite bonding, and mold release applications.
The silicone adhesive provides clean removal from various substrates without leaving residue, making it an efficient solution for temporary holding and protection. Ideal for aerospace, automotive, electronics, metalworking, and general industrial applications, this tape is engineered to withstand challenging conditions while maintaining reliable performance. Each roll delivers consistent quality and durability, backed by 3M's commitment to innovation and excellence in industrial adhesive solutions.
