GENERAL INFORMATIONalbf.JPG (9555 bytes)
ZIRCAR  Alumina-Silica Bulk Fiber Type ASBF is long alumina-silica fibers suited for the vacuum forming of low density shapes, for use as packing or as a bulk fill material. It is useful to temperatures of 1260C (2300F). 

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

These fibers and refractory binders yield a uniform body of  ~ 0.28 gm/cm3 (18 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.
