Bulk Fiber Type ASBF
GENERAL INFORMATION
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 1260°C (2300°F).
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.
