Flexible Expanded Graphite Roll

HY-G400

Expanded graphite sheet is an excellent sealing material for high temperature, high-pressure transfer of liquids, gases, steam, chemicals and corrosives. It is manufactured from high purity, high crystalline natural graphite flakes, which are processed into continuous foil by a special acid and thermal treatment to produce expanded graphite crystals. The expanded graphite crystals are then formed into foil through an extensive calendaring process without any resins and binders.
