HPMS expandable graphite is manufactured from
natural crystalline graphite flake through an
intercalation chemical process. The expandable
graphite is low in density and halogen-free. The
expansion temperature starts at 150 to 220 °C
and the expansion volume can be as high as 350 times
its original volume. Typical applications include
lubricants, graphite foil manufacturing, bipolar plates
in fuel cell applications, fire retardant additive in
plastics and fire retardant foams for insulation.
