What Are Graphite Foils?

Graphite foils are specialized thermal interface materials made from highly compressed natural graphite without binders. Through rolling or pressing processes, thin, flexible foils or stiffer sheets are produced. 

alfatec primarily offers the Kerafol Graphite S 900 series, composed of pure, highly oriented natural graphite. While synthetic graphite foils exist, we focus on the advantages of natural graphite in the S 900 series. Its structure results in exceptional thermal conductivity.
