Geegraf Stainless Steel Tanged Graphite

A graphite sheet material mechanically bonded and available in one metre square sheets or cut gaskets. The material comprises two outer layers of graphite foil with a central tanged stainless steel core 0.1mm thick. The layers are mechanically pressed together in-house with a laminating technique that does not delaminate during punching, storage and use.
