Manufactured
by carbonizing and - optionally - graphitizing natural and synthetic fibers, SIGRATHERM here is a soft and flexible insulation material,
in the form of sheets or coils.
Characteristics and Benefits
|
 |
Low thermal conductivity
Superior to that of loose particle fillings like granular carbon or metal radiation shields (saving in energy up to 75 %).
|
|
Low specific heat
Permits rapid heating and cooling of furnace.
|
|
High thermal stability
In oxidizing atmosphere up to 350°C, in protective atmosphere
or vacuum up to about 3000°C.
|
|
Favourable resistivity
Coupling in an inductive field occurs only above 12 kHz.
|
|
Ease of handling
Can be cut with scissors or knife. Flexible – adapts to small
bending radii.
|
|
Favourable surface properties
Unaffected by nearly all molten metals. Small specific surface area
– low adsorption capacity; surface may be increased by partial
oxidation.
|
|
High purity
Low sulphur content – no contamination of pump oil in vacuum
operation. Low ash content – no smouldering.
|
|
Very uniform structure
Smooth and flat over long lengths (25 m). Uniform thickness, hence
constant insulating properties.
|
|
No electrostatic charging
No electrostatic charging when used together with plastics in composite
materials.
