Thermal Interface Material
Graphite Sheet
T68 Artificial Ultra Thermal Conductive Graphite Sheet is highly oriented pyrolytic graphite sheet with high thermal conductivity. A heat source can reduce temperature by spreading heat over the T68. It is flexible and has features of ultra-thin and high EMI shielding effect. It is :
●Ultra high thermal conductivity,electrical conductivity and EMI shielding effect
●Flexible, and bendable
●Ultra thin; Low mass; Environmental
●Low thermal resistance
Application
Smart phones, Laptops
LED back light, PDP/LCD/OLED screens, Ultra bright LED
Digital camera, Digital video camera, NIC
