T68
Graphite Sheets
T68is a 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.
Features
Excellent thermal conductivity: 1600 W/mK (4x as high as copper, 7x as high as aluminium)
Lightweight: Specific gravity: 2.3g/cm3
Flexible and easy to be cut or trimmed
Low thermal resistance
Low moisture content: ‹1%
Applications
Smart phones, mobile phone, NB, Tablet PC
LED backlight, PDP / LCD / OLED display, High power LED
DVC, DVS, PC card
