This premium series of Teflon tape is
manufactured by coating one side of our
#502 fabric with
a pressure sensitive adhesive. The fiberglass substrate has a
tighter weave than that of standard grade material, and a higher
Teflon content for maximum release properties. This series
should be considered where performance is the main purchasing
consideration.
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.
