“PGS” Graphite Sheets
“PGS” Graphite Sheets
Type:
EYG
“PGS (Pyrolytic Graphite Sheet)” is a ther mal
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.
"SSM(Semi-Sealing Material)" is the product which is
compounding PGS Graphite sheet and High thermal
conductive Elastomer resin. It has a function to absorb
heat by resin and release the heat by utilizing high
thermal conductivity of PGS Graphite sheet. It also
enables taking better attachment to the component
which has different height on the electronic board,
reducing stress to the electronic board.
Features
●
Excellent
thermal conductivity : 700 to 1950 W/(m·K)
(2 to 5 times as high as copper, 3 to 8 time as high as aluminum)
●

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
●
Low heat resistance with flexible Graphite sheet (SSM)
