3M PTFE Extruded Film Tape 5491, thicker version of Tape 5490, PTFE extruded film with silicone adhesive.
Extruded film with silicone adhesive, provides an exceptionally slick surface when applied and resists curling during unwind. Chemical resistant surface for sealing and masking.CAUTION:
When PTFE film tape is exposed to temperatures above 600°F (316°C), small quantities of hazardous vapors may be released. INHALATION OF THESE VAPORS MAY BE HARMFUL OR MAY CAUSE RESPIRATORY TRACT IRRITATION. Do not heat or expose PTFE film tape to temperatures above 600°F (316°C).Benefits:
- Extruded, calendered film tapes that resist curling during unwind and provide an exceptionally smooth surface when applied
- Extruded PTFE film tapes lie flatter than typical skived PTFE film tapes
- Thicker backing helps extend the service life, compared to thinner versions, when subjected to abrasion or wear
- Provides excellent chemical resistance except to organic solvents. Note: The silicone adhesive will be attacked by commercial organic solvents and is not recommended for applications requiring organic resistance
