Products Details
Description:Flexible graphite sheet is made with pure expanded graphite. “Sungraf”brand flexible graphite sheet has a high purity of 99% carbon content
Advantages
better chemical resistance, better thermal conductivity, and better sealability.
Usage
-
01
As gasket material, it is usually fabricated into Graphite Laminate, reinforced graphite sheet
-
02
widely used in fluid sealing applications: flange gasket, spiral wound gasket, heat exchanger gasket, etc.
-
03
It can also be used as solid lubricant in metal stamping and forming applications, or as heat liner in industry furnaces and other heating device.
