Keratherm Graphite 90/10 - MH&W Thermal Products

Keratherm Graphite Films are based onto 100% graphite material. The films are available as uncoated versions or for specific applications, provided with hot-setting wax coatings, filled or standard adhesives.

Because of their high heat conductivity, these films are used, among others, in the CPU field.

Possible Thickness:
90/10: 0.15mm – 0.20mm
90/25: 0.125mm discontinued
