“PGS” Graphite Sheets
“PGS” Graphite Sheets
Type:
EYG
PGS (Pyrolytic Graphite Sheet) is a thermal interface
material which is very thin, synthetically made, has
high thermal conductivity, and is made from a higly
oriented graphite polymer film. It is ideal for providing
thermal management/heat-sinking in limited spaces
or to provide supplemental heat-sinking in addition to
conventional means. This material is flexible and can
be cut into customizable shapes.
●
Excellent thermal conductivity : 700 to 1750 W/(m·K)
(2 to 4 times as high as copper, 3 to 7 time as high
as aluminum)
●
Lightweight: Specific gravity : 0.85 to 2.1 g/cm
3
(1/4 to 1/10 of copper, 1/1.3 to 1/3 of aluminum in density)
●
Flexible and easy to be cut or trimmed.
(withstands repeated bending)
●
Low thermal resistance
●
RoHS compliant
