These insulators have a distinctive amber color and can be easily recognised and assembled on a production line Browse Heat sinks - By Device - ThermalfilmTMMT, made from high performance KaptonTMMT material, provides thermal conductivity nearly 2-5 times greater than standard ThermalfilmTM. - By Product Line -Attachment Methods- - Interface Materials - - Accessories - Useful Links * MSDS Safety Sheets * How to order? * Find Sales Rep * Find Distributor * Sample Request * Quote Request * Catalog Request * Building a part # * Part # Cross Ref 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 is rated 94 V-O. Notes: ThermalfilmTM MT part numbers begin with "46". Insulator thickness is .05mm +/- 0.006mm (0.002" +/- 0.00025") unless otherwise specified. Dimensional tolerances are +/- .38mm(.015"), hole diameters are +/- .25mm (.010") and angularity is +/- 1 1/2 unless otherwise specified.
