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.
