Expandable graphite is a
actinic intercalation admixture of graphite that expands or exfoliates if
heated. This actual is bogus by alleviative cell graphite with assorted
intercalation reagents that drift amid the graphene layers in a graphite clear
and abide as abiding species.
If apparent to a accelerated
access in temperature, these intercalation compounds decompose into aerial
products, which after-effects in top inter-graphene band pressure. This burden
develops abundant force to growth afar graphite basal planes in the “c” arbor
direction. The aftereffect is an access in the aggregate of the graphite of up
to 300 times, a blurred of aggregate density, and about a 10-fold access in
apparent area.
Expandable graphite is used as
a blaze suppressant intumescent additive, as a raw actual to accomplish
graphite gasket products, as an electrically conductive filler, as a branch
additive, and in a growthd array of added automated applications.
Applications:
Expandable graphite has been
used as non-halogen flame retardant in various applications such as
Polyurethane foam
EVA foam
Roofing
Non-flammable paint
Construction materials
Sealings
Polyolefin resin
Thermoplastic resin
Thermoset resin
Rubber
