Industrial-grade PTFE film tape with silicone adhesive for friction reduction and non-stick applications. Features extruded backing, wide temperature range, excellent chemical resistance, and clean removal properties.
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 specialized tape delivers an exceptionally low coefficient of friction, creating a smooth, non-stick surface ideal for reducing friction between moving surfaces in demanding industrial applications. The 12-inch width and 36-yard length provide ample coverage for large-scale manufacturing and processing operations.
The tape's extruded PTFE backing resists curling when unwound and lies flatter than conventional skived PTFE film tapes, ensuring a more uniform non-skid surface. With a total thickness of 6.7 mil and a backing thickness of 5 mil, this tape offers superior durability and longer wear compared to the thinner 5490 model. The silicone adhesive provides clean removal from various surfaces without leaving residue, making it ideal for temporary applications where easy removal is essential.
Designed for industrial and occupational use, the 3M PTFE Film Tape 5491 operates reliably across a wide temperature range from -65°F to 500°F (-54°C to 260°C), making it suitable for heated machinery, equipment, and high-temperature applications. Its excellent chemical resistance enables the tape to withstand challenging environments and serve as a temporary chemical barrier. With a 24-month shelf life and proven performance in aerospace, automotive, electronics, and metalworking industries, this tape is an essential solution for reducing friction, noise, and machinery wear.
