“PGS” Graphite Sheets
EYG type
“PGS (Pyrolytic Graphite Sheet)” is a thermal conductivity sheet
which is very thin, synthetically made, has high thermal
conductivity, and is made from a polymer film.
It is ideal for providing thermal management/heat-sinking in limited spaces.
This material is flexible and can be cut into customizable shapes.
Features
● Excellent thermal conductivity : 700 to 1000 W/(m·K)
(2 times as high as copper, 3 to 5 time as high as aluminum)
● Lightweight: Specific gravity : 0.85 to 1.00 g/cm3
● Flexible and easy to be cut or trimmed. (withstands repeated bending)
● Low thermal resistance
● RoHS compliant
Recommended applications
● Semiconductor manufacturing equipment (Sputtering, Dry etching, Steppers)
● Optical communications equipment
● TIM(Thermal Interface Material)
