China Expanded Graphite Sheet supllier ,reinforced graphite sheet ,tanged graphite sheet,flat graphite sheet.
Expanded Graphite Sheet are chemically treated to form graphite intercalation compounds, which are then heated to separate rapidly.As a result, it turns into a granular puff, and the density of this worm like graphite powder is about 0.003g/cc. Then, the graphite plate is formed by rolling.
Application of expanded graphite sheet
Made graphite died form packing ring.
Made expanded graphite gasket for flange
Expanded graphite sheet is directly and effectively applied to metal surface of gas seal.The expanded graphite sheet, especially the expanded graphite coil, can be used as the material of the automatic production line.
