3M 5491

3M 5491 uses an extruded polytetrafluoroethylene (PTFE) film backing.

This tape offers an extremely low coefficient of friction which, in combination with a pressure-sensitive silicone adhesive, creates a smooth, non-stick surface over a variety of substrates to assist in the movement of materials in many types of lay-flat applications.

• Color: Brown, Gray
• Thickness:0.17 mm, 0.094 mm
• Backing: Extruded PTFE
• Adhesive: Silicone

• Extruded film backing resists curling when unwound from the roll and lies flatter than skived PTFE film tapes, creating a more uniform non-skid surface.
• We developed this tape as a quick and easy solution to reduce friction between moving surfaces.
• It functions as an anti-stick or easy-release medium where pressure, temperature changes, and other factors may create a measure of adhesion.
• Applying 3M™ PTFE Film Tape 5491 can help improve surface movement, eliminate squeaks and rattles, and reduce machine noise.
• PTFE is chemical resistant and can be used as a temporary chemical barrier.
• The tape has a wide temperature use range, from -65°F/-54°C to 500°F/260°C, making it a suitable choice for a variety of applications.

• Non-stick PTFE film provides an exceptionally slick surface for easy clean-up
• Silicone adhesive provides clean removal from a variety of surfaces
• Wide temperature range for performance on heated machinery and equipment
• Thicker version of 3M™ PTFE Film Tape 5490, providing more durability and longer wear
• Extruded 3M™ PTFE Film Tape lies flatter than typical skived PTFE film tapes
• Excellent chemical resistance enables the tape to withstand challenging applications
• High strength and abrasion resistance ensure reliability and performance to reduce friction, rattle, and machinery noise

• Roll-wrap for web processing, belts, and plates where sticky materials and inks may occur
• High-temperature wire bundling and harnessing
• Squeak and noise reduction
• The lining of chutes, troughs, and ducts
• Shielding and protecting against chemicals
• Mold release for composite bonding
