Thermally Conductive Material
Thermally Conductive Material is developed for the radiator of electronic products which require high thermally conductive and reduce the weight more than 50% compare with the same aluminum devices.

Features
>Good thermal conductive: 2-20W/mK
>Excellent thermal conductivity compared to normal
engineering plastics
>Light than normal Aluminum housing 50% in weight
>Excellent mouldability in injection moulding
>Much higher production yield than normal Aluminum Die Casting
>Excellent flexibility in designing final pruducts such as housings.
>Flame resistance, UL94 V-0

Application
Used in applications such as Heat Sinking Housing at LED-lit BLU in LCD/LED TV and LED-lit lamps Also it can replace the normal Aluminum heat sink.
