Which Adhesive System Should You Use?
Acrylic Adhesive Teflon tapes
usually have a blue liner. The adhesive itself is aggressive and
has an extended shelf life over a narrower range of temperatures
(-100 F to 350 F). In some cases these tapes can handle the the
intermittent temperatures required for impulse sealing.
Silicone Adhesive Teflon tapes are
supplied with a yellow release liner. This would be the best
choice when applying to a heated surface, and has an operating
temperature range of -100 F to 500 F. Normal shelf life is
between 12 & 18 months.
