ZIRCAR Ceramics produces a wide range of alumina-silica fiber based insulation products. Some of these products have unique properties and characteristics others are more utility grade. Their densities cover a wide range from 12 pcf of Type ECO-1200 to a much harder and stronger  60 pcf of Type HASH-60. The range of sizes we produce is incredible and goes from small 1" x 1" x 1/8" pieces of HASH 60 used in electrical switching equipment to AXL staved cylinders the inside of which is large enough to heat treat a city bus.


Alumina-Silica Insulation Type ASH
ZIRCAR Ceramics Alumina-Silica Insulation Type ASH is one of the first alumina-silica products produced by ZIRCAR. Made of bulk fiber and inorganic alumina binders Type ASH is uniform throughout its thickness and contains no organic materials. It is useful to temperatures of 1260C (2300F).


Alumina-Silica Insulation Type AXL and AXHTM
ZIRCAR Alumina Silica Insulation Type AXL and Type AXHTM are inorganically bound insulation boards typified by their rigid outer surfaces and unbound interiors. They offer low thermal conductivity and excellent thermal shock resistance. AXL is designed for use to 1260C (2300F), AXHTM is useful to 1427C (2600F).


Alumina-Silica Insulation Type ECO-1200
This utility grade board is produced with or without organic binder. Useful to temperatures of 1260C (2300F) ECO-1200 is part of hundreds of different thermal process systems.

Alumina-Silica Insulation Type ECO-27
This utility grade board is produced with or without organic binder. Useful to temperatures of 1260C (2300F) ECO-27 offers exceptional strength and durability.


Alumina-Silica Insulation Type HASH-60
ZIRCAR Ceramics Alumina-Silica Insulation Type HASH-60 is a hardened insulation board used primarily for its high temperature dielectric strength in high power electrical switching equipment.

Alumina-Silica Insulation Type Z-500

Useful to temperatures of 1000C (1832F) Z-500 is uniformly rigidized and hard throughout its entire thickness, requiring no re-rigidizing after precision machining into complex shapes and configurations.


Alumina-Silica Insulation Type "UNIFORM A"

A new family of insulations with exceptional machineability and strength. Made of specially prepared alumina-silica based refractory ceramic fibers with uniformly distributed inorganic silica binder they are useful to temperatures of 1260C (2300F)
