Options for Keratherm - Graphite:
Keratherm® graphite films are based on 100% pure graphite. The films are available as uncoated types or for specific
applications, coated with thermal wax, filled adhesive or standard adhesives. Because of their high thermal conductivity
they are used e.g. in the CPU sector.
Available thicknesses: 0,200 mm, 0,250 mm, 0,350 mm, 0.750 mm, 1,00 mm
