Flexible Graphite Foil & Sheet is made from exfoliated graphite flake and is produced through an extensive calendaring process to give a thin flexible foil with no binder or resins.
Because of the excellent properties such as thermal stability, high and low temperature resistance, impermeability and corrosion resistance, etc. Flexible Graphite Foil is widely used in fields of industrial sealing, heating elements for high temperature applications and insulation/heat shields.

Why use Flexible Graphite
Flexible graphite is the best material available today. Inert carbon will not corrode.
Unaffected by chemicals. True chemically inert material, handles 0-14 ph spectrum.
Steam temperature range to 1800 .
Excellent compressibility and recovery (spring back).
Seals with low bolt loads.
Conforms to smooth or irregular sealing surfaces.
Absence of binder means no ageing or embrittlement.
Absence of health hazard.
Low thermal expansion characteristics.
Indefinite shelf life, natural graphite material has already undergone millions of years of aging in the earth's crust.
