Expanded Graphite Sheet LGRHDI

Expanded Graphite Sheet LGRHDI Planigraph™


The graphite gasketing sheets LGRHDI are the greatest material to make gaskets for high temperature and high pressure services for RF, FF, LMF and LTG piping and heat exchangers flanges. LGRHDI shows a great value of relaxation with an excellent mechanical strength.
