ALF
About ALF
ALF™ is generally called Alumina Fiber. As the composite is 72% Alumina and 28% Silica, we name it Alumina Silica Fiber. The standard product/yarns are produced as a 7 micron diameter filament and are boron free. The 7 micron diameter allows superior flexibility compared to other available materials. Furthermore, because the fiber is boron-free, problems associated with the release of boron gas are not a factor. Performance and durability of Hiltex Alumina Silica Fiber is superior to other products presently available. ALF suffers almost no loss of mechanical strength at temperatures up to 1200º C.
We also have several types of fabrics, sleeves and yarns with 2% boron which can be used for applications approaching 1395ºC, this called out FB3 type.
ALF is available as woven cloth, braided sleeve, tape, rope, yarn and sewing yarn
and is appropriate for countless applications including the following:
- Thermal insulation rings
- Furnace linings
- Heat-shielding curtains
- Thermal insulation sealers or packing materials
- Thermal insulation coverings for thermocouples, cables and wires
- Roller covers for tempered glass plate manufacturing
- Filters for molten metals
- Spacers for heat treatment
| | - Abrasives for plastic whetstones
- Insulators around generator and aircraft/rocket engines
- Catalyst carriers
- Electrical and thermal insulators for diesel particulate filter (DPF) systems
- Alumina-silica fiber reinforced plastics (FRP), insulation and structural materials for cryogenic apparat uses
- Alumina-silica fiber reinforced metals (FRM)
- Matrices for ceramic composites
