High density SIGRATHERM flexible graphite foil is a homogeneous material manufactured from natural graphite without the use of adhesives or binders.
SIGRATHERM HD graphite foil’s excellent thermal as well as electrical conductivity are both anisotropic, i.e. have a high degree of directional dependence. As the degree of compression rises, the individual graphite crystals are increasingly oriented within the sheet plane. As a result, the anisotropy of conductivity becomes more pronounced.
The advantages of SIGRATHERM® High Density Graphite Foil are:
0.15 - 1.5 mm
