MT Thermally Conductive Polyimide Film

 

MT Polyimide Film (e.g Kapton® MT Film) is a thermally conductive film, possesses higher thermal conductivity properties than standard polyimide film. This property makes it ideal for applications requiring efficient thermal energy transfer, such as loudspeaker voice coils frame, electrical insulating pads and flexible printed circuit board. Moreover it also can offer an excellent combination of electrical, physical and mechanical properties.

Characteristics

 • Excellent thermal conductivity

 • Good dimensional stability

 • Chemical resistance

 • Flame resistance UL V-0

 • High and low temperature resistance

Application:

       • Voice coil frame of loudspeaker

       • Flexible Printed Circuit (FPC)

 Insulation Pads (heat sink)

  • Ceramic board replacement
