Microwave Furnace Insulation

Rath offers a broad range of products for temperatures up to 1800° C for thermally-insulating microwave furnaces. Rath materials have low levels of impurities, resulting in minimal dielectric loss. The low mass and minimal dielectric heating of Rath material ensure rapid temperature increase of the load with minimal energy lost to the furnace lining.

Rath offers complete furnace kits incorporating
Vacuum-formed Insulation.
