  • Expandable Graphite Powder - China

    price: 2000.00 Dollar US$

    Expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates when heated.

    Once heated, it results an increase in the volume of up to 400 times, a lowering of bulk density, and approximately a 10-fold increase in surface area.

    Then it’s compressed into a highly cohesive flexible sheet.

    Another principal application is as a flame retardant.

    As a result of the heat of a fire the graphite expands and creates an intumescent layer on the surface of the material.
