ALTRA® Kerasetter Ultra High Density Vacuum Formed

ALTRA® Kerasetter
Ultra High Density Vacuum Formed Boards
ALTRA® Kerasetter machinable board products are available in
formulations for service temperatures up to 1700C.
ALTRA®
Kerasetter boards are available for high temperature, oxidizing
environments (KVS) or high temperature, reducing environments
(KVR). ALTRA® boards are formed from alumina or mullite
polycrystalline fibers with appropriate inorganic and organic
binders. All grades are pre-fired to 1000C or greater, resulting in
an organic free composition. Possible applications include low
mass sintering setters.
