Thermalfilm™ and Thermalfilm™ MT are low cost polymide plastic insulating films designed
to be an improved replacement for mica.These insulators have a distinctive amber color and
can be easily recognized and assembled on a production line.
Thermalfilm™ MT, made from high performance Kapton™ MT material, provides thermal
conductivity nearly 2-5 times greater than standard Thermalfilm™. Both insulators have an
extremely high resistance to flow or thin out under high compressive stresses, particularly at
elevated temperatures. Excellent physical, mechanical and electrical properties remain nearly
constant over a wide range of temperatures and frequencies.They are radiation resistant,
have no melting points, and have no known organic solvents.The polymide plastic film is UL
listed as a component in UL’s publication “Component – Plastic Material” dated September
18, 1969. The UL card number is E39505R, Guide QMFZ2 filed by E. I. du Pont de Nemours
& Co., Inc. Thermalfilm
TM
is rated 94-V/0.
