Keratherm® graphite films are based on 100% pure graphite. The films are available as uncoated types and for specific applications, with filled adhesive or standard adhesives.

Because of their high thermal conductivity they are used e.g. in the CPU sector.

Keratherm® - Graphite S 900 is a highly densed natural graphite without binding material which is rolled or pressed into films or plates. S 900 has exceptional qualities and is therefore used particularly as a cost-effective alternative to conventional interface material. Especially the anisotropy of the thermal properties, coupled with a possible weight saving of up to 30% compared to conventional materials made of copper or aluminum, makes the S 900 interesting for headspreader applications. In addition, applications in vacuum or even at high temperatures (400 °C) are possible. Graphite S 900 has no electrical insulation and can be customized and applied with an adhesive coating.
