ZIRCAR Ceramics Rigid Alumina Insulation products comprise a broad range of products available as boards, cylinders and custom shapes. Made of high purity raw materials these products bring significant utility to the high temperature applications they serve. A few features include:
Insulation Type SALI-2 SALI-2 is a premium grade rigid insulation
board used as hotface insulation or a precision machined furnace fixtures.
Insulation Type SALI SALI has been serving 1700°C low mass furnace
users longer than any other alumina fiber board available today. SALI is a premium grade
rigid fiber board with superior hot strength.
|Alumina Insulation Type AL-25/1700
AL-25/1700 is a rigid medium duty grade of alumina fiber board. Not as strong as SALI but
capable of delivering years of service.
|Alumina Insulation Type AL-30AAH AL-30AAH was
developed for use in copper vapor lasers where the ultimate in low mass alumina purity is
Insulation Type ZAL-45 & ZAL-45AA ZAL-45 is an exceptionally
strong low density alumina fiber product. Alumina bonded ZAL-45AA is useful in reducing
ZAL-45: 1650°C (3002°F)
ZAL-45AA: 1500°C (2822°F)
Insulation Type AL-30 & AL-30AA AL-30 and AL-30AA are rigid
alumina fiber boards characterized by uniform open porosity and high
Alumina bonded AL-30AA is used in fuel cell reformers.
AL-30: 1600°C (3002°F)
AL-30AA: 1500°C (2822°F)
Insulation Type ECO-20AA ECO-20AA is most commonly utilized as hotface
insulation in furnaces with hydrogen rich atmospheres such as bright annealing furnaces.
Insulation Type ZAL-15 & ZAL-15AA ZAL-15 is a low thermal
conductivity uniformly bound fiber board. It is ideal for machining into precision thermal
ZAL-15: 1550°C (2822°F)
ZAL-15AA: 1550°C (2732°F)
Insulation Type ALC & ALCAA ALC is the same material as ZAL-15 -
but brings exceptional uniformity in an insulation material in cylindrical form.
ALC - 1550°C (2822°F)
ALCAA - 1550°C (2732°F)
