Details

 

Thermal conductive MT polyimide film is a homogeneous film possessing high thermal conductivity. While maintaining the excellent electrical, physical and mechanical strength of standard polyimide film. These properties make it ideal for applications requiring efficient thermal energy transfer, such as loudspeaker voice coils frame, electrical insulating pads and flexible  printed board. The film can also be coated with FEP fluoropolymer resin or pressure sensitive adhesives.

Thermal Conductive MT Polyimide Applications

 

Flexible Heater

Thermal conductive MT polyimide film offers an excellent balance of electrical, thermal, mechanical, physical, and chemical properties over a wide range of temperatures. It is this combination of useful properties at temperature extremes that makes it a unique industrial material. When combined with etched foil elements, produces very thin flexible, heat conductive, customizable heaters and heater assemblies. Kapton is compatible with foil element alloys as inconel, nickel, copper, Balco, and many stainless steels.  These dielectric insulators have low outgassing properties, are resistant to a myriad of chemistries.

Heat Sink Pads

Thermal conductive MT polyimide can be used to make thermal pads. By coating the film with thermally conductive acrylic pressure sensitive adhesive and thermally conductive silicone rubber. Thermal conductivity pads minimize thermal resistance from the external package of a power semiconductor to the heat sink,  electrically isolating the semiconductor from the heat sink and providing sufficient dielectric strength to withstand high voltage. They are also strong enough to resist puncture from the facing metal surface.  Ideal to be used as thermally conductive gaskets for high performance electronics where low thermal resistance and high dielectric strength are required.
