Expanded Graphite Sheet LGRF Planigraph™


The expanded graphite jointing sheets LGRF Planigraph™ are available to make any type of flat gasket for industrial applications in high teperature. The graphite can works with all industrial streams and steam, except the strong oxidizers. The graphite LGRF gaskets have a dramatically low relaxation value (DIN 52913) and do not require retightening after thermal and pressure cycles.
