High Pressure Dynamic Sealing Graphite Gasket Sheet Smooth Finished Industrial Grade
High Pressure Industrial Graphite Sealing Gasket Products Description Product Range Flexible graphite solutions encompass sheets, foil, tape, strips, and paper-form variants, collectively known as expanded graphite materials. Manufacturing Process Natural graphite flakes undergo chemical intercalation followed by rapid thermal expansion at 800-1000°C, creating exfoliated graphite particles with a bulk density of ~3 kg/m³. These expanded particles are mechanically compacted
