Polyken 296FR Flame-Retardant Duct Tape
Polyken 296FR is a white flame-retardant duct tape built on a fiberglass cloth backing with an acrylic adhesive system. It measures two inches wide by thirty-six yards long at a seven mil thickness. The roll is rated for continuous service between forty and two hundred seventy-five degrees Fahrenheit and delivers forty-five ounces per inch adhesion to steel. It suits aviation, HVAC and general repair tasks that require a fire-resistant seal indoors or outdoors.
Thermals noise and power draw in normal use
The tape operates passively with no power draw and no moving parts so it generates no noise and adds no thermal load to the system. Its acrylic adhesive maintains bond integrity across the full forty to two hundred seventy-five degree Fahrenheit range without softening or becoming brittle. The fiberglass cloth backing resists flame spread and does not melt or drip when exposed to elevated temperatures within the rated window.
Upgrade path and when the jump is worth it
This product replaces standard cloth duct tapes that lack a flame-retardant rating or that degrade outside a narrow temperature band. The jump is worth it when the application demands a verified fire-resistant seal on ductwork, cargo pits or equipment wraps that see sustained heat or cold beyond what conventional tapes tolerate. Buyers who need a tape without a fiberglass backing or who require a different adhesive chemistry should look elsewhere.

Questions about this item
How do I apply the 2 in wide glass-cloth tape so the acrylic adhesive bonds properly?
Clean the surface, press the tape firmly along its full 36 yd length, and smooth out air pockets; the acrylic adhesive reaches full strength after dwell time at room temperature.
What will degrade first on the flame-retardant duct tape during long-term exposure?
The acrylic adhesive and glass-cloth backing are rated for continuous use between 40 and 275 Degrees F; sustained temperatures outside that range will cause the tape to lose adhesion or become brittle first.
At what temperature does the 7 mil tape hit its performance limit under sustained heat?
The maximum continuous performance temperature is 275 Degrees F; above this the adhesive and glass-cloth backing can degrade and lose the rated 45 oz/in adhesion to steel.
