3M Extruded PTFE Film Tape | SKU 5490: 3/4 in. x 36 yds. (Brown)

3M 5490 Extruded PTFE Film Tape pairs a 2 mil extruded PTFE (polytetrafluoroethylene) film carrier with a pressure-sensitive silicone adhesive, creating a slick, non-stick surface that helps materials move freely across rollers, plates, belts and slide surfaces. Rated for long term use from -65 degrees F to 500 degrees F.

Features

• Extremely low coefficient of friction for smooth, non-stick performance
• Lies flatter than skived PTFE film and resists curling on unwind
• Thicker backing extends service life under abrasion and wear
• Silicone adhesive removes cleanly from a wide range of surfaces
• Excellent chemical resistance, except to organic solvents

Applications

• Roll wrap for web processing on belts and plates where inks build up
• Easy-release surface on rollers, formers and slide plates
• Release surface for composite and metal bonding tooling
• Chemical-resistant masking and sealing
• Squeak, rattle and machine noise reduction
