Rigid Graphite
Fibreboard - GT-0100 Vacuum Furnace Insulation
|
 |
Ceramisis GT-0100 fibreboard vacuum furnace insulation. is a
high temperature rigid thermal insulation material used
extensively in vacuum furnaces and inert atmosphere furnaces.
Manufactured from woven PAN based carbon fiber, GT-0100 has
excellent insulation properties.
Standard board size: 40 x 1000 x 1500mm. Boards can also be cut
to size to suit specific requirements..
|
|
Our fibreboard
vacuum furnace insulation is also available with heat reflective
graphite foil facing on both sides to reduce particle count and
improve its insulating properties. This board is denoted GT-0101.
|
 |
 |
Where
extra mechanical protection is required we can supply our
fibreboard vacuum furnace insulation with a carbon carbon
composite (CCC) facing on both sides, denoted GT-0103. It can
also be supplied with one foil face and one CCC face which is
denoted GT-0104. |
|
In addition to rectangular boards we produce bespoke cylinders
and discs to suit tubular furnaces. These are also available
with foil facing or graphite paint coating.
|
 |
 |
For
protecting exposed areas carbon carbon composite formed strips
are available. These come in "L", "U" and "H" shape sections.
Standard
strip length is 1000mm.
We also
have a range of carbon carbon composite nuts and threaded
studding from M6 to M20.
