Zircar Ceramics Uniform A1 Alumina-Silica Insulation

ZIRCAR Alumina-Silica Insulation Type "UNIFORM A"  is a family of refractory ceramic fiber based insulations with exceptional machineability and strength. They are made of specially prepared alumina-silica based refractory ceramic fibers with inorganic silica binder which is uniformly distributed to create an evenly bonded material.

UNIFORM A materials contain no organic binders and produce no smoke or odor when heated. They exhibit excellent resistance to chemical attack at elevated temperatures making them useful in many varied high temperature applications.

Features:

• Low thermal conductivity
• Excellent thermal shock resistance
• Thermal stability in applications to 1260°C.

Typical Applications:

• Primary thermal insulation in low mass furnaces and thermal process systems operating to 1260°C (2300°F).
• Backup thermal insulation in furnaces and thermal process systems operating to high temperatures.
• Reflector tiles in infrared paper drying equipment.
• Launders, distribution boxes, pouring spouts, hot tops and others involving molten metal contact.
• Furnace and kiln flue and chimney linings.
• Combustion chamber liners, baffles and muffles.
• High temperature setters, supports and process fixtures.
• Electrical insulation in high temperature systems operating to 1260°C (2300°F).
• Thermal insulation in hot appliances.
