Features
? Flame resistant. Meets U.L. 723, Class “L” low flammability rating (File R 7311).
? Meets requirements of F.A.R. 25.853(a).
? Foil backing provides an excellent reflective surface for both heat and light.
? Aluminum foil backing and acrylic adhesive system combine to offer long aging
both indoors and out.
? The high coefficient of expansion offered by the aluminum allows expansion and
contraction with changes in temperatures, along with thermal conductivity.
? Performs in a range from -65° to over 300°F (-54° to 149°C). Higher temperatures
for shorter periods of time.
