Premium 3M PTFE film tape with non-stick silicone adhesive, 1 inch width, 36 yard length, ideal for reducing friction and noise in industrial applications with wide temperature range -65°F to 500°F.
3M™ PTFE Film Tape 5491 is a premium industrial adhesive tape designed for applications requiring exceptional non-stick properties and low friction performance. This brown PTFE film tape features an extruded polytetrafluoroethylene backing combined with a pressure-sensitive silicone adhesive, creating an exceptionally slick surface ideal for easy clean-up and material movement. The tape measures 1 inch in width with 36 yards of length per roll, supplied in cases of 7 rolls, making it perfect for high-volume industrial operations.
The extruded PTFE film backing resists curling when unwound and lies flatter than typical skived PTFE film tapes, providing a more uniform non-stick surface. With a total thickness of 6.7 mil (0.17mm), this tape offers superior durability and longer wear compared to thinner alternatives. The silicone adhesive ensures clean removal from a variety of surfaces without leaving residue, while the PTFE material provides excellent chemical resistance and enables the tape to function as a temporary chemical barrier. The wide operating temperature range from -65°F to 500°F (-54°C to 260°C) makes it suitable for applications involving heated machinery and equipment.
3M PTFE Film Tape 5491 is engineered to reduce friction between moving surfaces, eliminate squeaks and rattles, and reduce machine noise in industrial settings. Recommended applications include roll-wrap for web processing with sticky materials and inks, high-temperature wire bundling and harnessing, squeak and noise reduction, lining of chutes and troughs, chemical shielding, and mold release for composite bonding. The tape delivers high strength and abrasion resistance, ensuring reliability and consistent performance in demanding industrial environments. For industrial and occupational use only, this product is not intended for consumer sale or use.
