EXPANDABLE GRAPHITE
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 degree C
and the expansion volume could be as high as 350
times of 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.
