Compared to other industrial graphite foils, various SIGRAFLEX grades exhibit remarkable oxidation resistance. Unrivaled “Best in Class” and therefore the material of choice especially for refinery gaskets is APX2 graphite foil: APX2 stands for unchallenged best oxidation resistance in the market.
Using AX2 foil e.g. as soft facing material for Kammprofile gaskets or as filer in spiral wound gaskets significantly extends the gasket service life, increases process reliability and reduces costs on the long term.

Refinery operators benefit from the use of packings made of high quality and high-purity oxidation resistant yarns from SGL Carbon. They offer a unique combination of tightness and heat dissipation, excellent high-temperature and chemical resistance, as well as reduced contamination of processes due to the high purity of the yarns.
Our SIGRAFLEX materials made from expanded flexible graphite and our SIGRAFLEX packing yarns have proven their long-term stability under extreme operating conditions over the course of many years – especially when used in refineries.
