Flexible graphite, or grafoil as also being called, is made from
mineral (flake) graphite. As
it has the flexible nature, so it is named as flexible graphite, to
distinguish it from other forms of graphite materials: mineral
graphite (including flake graphite and amorphous graphite), artificial
graphite (including graphite electrodes and scrap granules,
graphitized/carbonized rayon or other synthetic materials such as
graphitized carbon fiber, graphite golf club etc.)
Natural mineral graphite is unique. It is a non-metallic mineral, but
is thermal and electrical conductive like metal. It is formed with
element carbon, same as the hardest mineral - diamond, but graphite is
the softest mineral. Natural mineral graphite is inert to most
chemicals, resists to heat of several thousand degrees. All these
characteristics attribute to mineral graphite crystalline structure.
In the structure, the hexagonal bond is strong, but the bond between
layers is weak. By breaking the bond between layers, the mineral
graphite can be exfoliated several hundred times bigger. Compressing
the exfoliated graphite into sheeting form, hence the flexible
graphite is made.
Flexible graphite inherits all the unique characteristics of mineral
graphite and is being used in wide range of industrial applications.
First of all, it is a super sealing material and can be used for
making chemical and high temperature resistant gaskets, seal parts,
compression packing, etc. Flexible graphite is naturally a solid
lubricant and can also be used in various metal fabrication or other
mechanical processing works. Using its directional heat conduct
characteristics, flexible graphite is also being used as liners in
industrial furnaces, as well as in electronic devices to control and
spread heat flow…
