GENERAL INFORMATIONalbf.JPG (9555 bytes)
ZIRCAR  Alumina-Silica Bulk Fiber Type ASBF-1 has been specially processed to remove "shot" and other un-fiberized material. This extremely "clean" material contains relatively short length fiber. It is suitable for use in vacuum forming of rigid boards and shapes and as a bulk fill material. It is useful to temperatures of 1260C (2300F). 

ASBF-1 fibers exhibit light weight, low  thermal conductivity, low thermal mass and immunity to thermal shock. 

ASBF-1 fibers and refractory binders  yield a uniform body of  0.24 -0.32 gm/cm3 (15-20 pcf) density, when vacuum formed from a water slurry. Silica or alumina binders can be used to form rigid refractory thermal insulation products. It is also useful as insulation packing in furnace spaces, around furnace sight tubes & ports and fill in expansion joints and masonry cracks.
