Kaowool Boards are produced from refractory fibre compositions specially
developed to give rigid, self-supporting boards with
excellent high temperature properties.
Board is designed for use in applications requiring higher
rigidity than blanket forms, and, as a result of its higher
density, has improved thermal insulation properties and
Kaolin boards are obtained by vacuum forming
process. The process allows the production of white
boards in a wide dimensional choice, with an excellent
homogeneity throughout the thickness which ease
machining of the boards when needed.
Strong Board is produced by the addition of selected
refractory fillers to the ceramic fibre in order to improve its
mechanical properties. Strong Board has two times the
strength of 1260 Board, both when measured fired and
All Board formulations contain a small amount of organic
binder to improve the cold handling strength and this
burns out on first firing at approximately 200-300°C. Heat
treatment can be made to burn the organic binders on
Vacuum formed boards.
CLASSIFICATION TEMPERATURE :-
From 1260°C up to 1600°C, depending on grade.
MAXIMUM USE TEMPERATURE :-
The maximum use temperature depends on the
• Rigid, self supporting boards.
• Low thermal conductivity.
• Good abrasion resistance.
• Low heat storage.
• Resistant to thermal shock.
• Not wetted by most molten non ferrous metals,
• Good resistance to spalling.
• Can be easily cut and shaped.
