Alumina fiber-based heat-insulation board
TOMBO™ No. 5461
RF BOARD™
RF BOARD is a product made by adding inorganic and organic binders to alumina fiber and then molding this into a board form.
As it is made of a fiber-based board, it has little heat storage volume. It can be used to design compact furnaces thanks to its excellent thermal insulation properties and workability.
Nichias has a lineup of various dense boards that are suitable for working temperatures of 1, 400°C to 1, 800°C or parts used in such an environment.
Therefore, it performs really well as a lining material for ultra-high-temperature electric furnaces and various high-temperature furnaces.
