Features
? 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.
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).
