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 400°F (204°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 400°F (204°C).

To help prevent wrinkling or bubbling of the backing on PTFE film tapes when they are subjected to temperatures above 250°F (121°C), pre-heat the surface to at least 150°F (66°C) (preferred 180°F, 82°C) to obtain best results.

APPLICATION IDEAS:

Easy-release surface on rollers, plates, belts, etc. where build-up of sticky materials and inks can occur.
Low coefficient of friction surface on rollers, formers, etc. to facilitate web movement.
Chemical resistant surface for sealing and masking.
Wrapping rubber nip rollers on hot polyethylene extrusion machines.

STORAGE:

Store under normal conditions of 60° to 80°F (16° to 27°C) and 40 to 60% R.H. in the original carton.

SHELF LIFE:

To obtain best performance, use this product within 18 months from date of manufacture.
