Refractory Ceramic Fiber Vacuum Formed Shapes - 3000 Series For 3000ºF Temperatures
Standard and special shapes with extremely low thermal conductivity and excellent thermal shock resistance Unique Composition Gemocolite Vacuum formed shapes are uniquely formulated from a

blend of high-purity alumina-silica fibers with an appropriate combination of organic and inorganic binders. Handling strength is provided by the organic binder, and product integrity at higher working temperature is maintained by the inorganic binder. No asbestos, phenolic binders or exothermics are used. Maximum use temperature for the standard formulation is 2300°F (1260°C). Formulations for use up to 3000°F (1649°C) are available. Special no smoke formulations are available. Outstanding Energy Savings Low thermal conductivity, low heat storage, and excellent insulating properties make Gemocolite® shapes important conservers of energy. Superior resistance to thermal shock permits quick heat ups and cool downs without cracking or spalling. Non-wetting properties and high refractory characteristics are distinct advantages. Applications include: Gaskets
Flue Liners
Range burner insulation
Burner Nozzle
Sleeves
Boards for furnace and kiln insulation and linings
Easily molded insulating wet blanket
Combustion chambers for oil or gas fired boilers
and water heaters
Secondary combustion chambers for solid fuel heaters
