Geegraf SSR Graphite Sheets & Laminates

Our stainless steel reinforced graphite sheet material comprises of two outer layers of graphite with a stainless steel core 0.05mm thick, we offer the complete process from selection of high purity graphite foil, laminating, curing and final inspection all carried out in house, by using our unique high temperature adhesive system giving a 100% bond we can convert the finished sheet in to gaskets with narrow land widths and/or complex geometry with no delamination.

All sheets can be water jet cut to create various shaped gaskets. On site we have our state-of-the-art water jet cutting machines which can provide you with precision cutting on our abrasive and water only machines. The process has been modified to suit the production of gaskets and now the most intricate designs can be cut accurately with no tooling costs offering a clean safe, smooth edge finish.
