Refractory Ceramic Fiber Vacuum Formed Shapes - 2600 Series

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.

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 and high refractory characteristics are distinct advantages.

* The intermittent use and the continuous use limit of GEMCOLITE® insulation is determined by irreversible linear change criteria, not product melting point.

Gemcolite® vacuum formed shapes can be surface treated on one or both sides to form an inorganic protective shell for extra strength. They can also be impregnated, so that the entire shape is almost rock hard throughout. This makes the shapes the strongest of all vacuum formed products, providing them with considerable resistance to mechanical abuse. All materials utilized for impregnation and surface treatment are inorganic and refractory.

Shapes can be cemented together in a strong bond to form larger or more complex configurations. This operation can be done in Refractory Specialties plant or at the users facility. Appropriate cement is available upon request.

Gemcolite® shapes resist oxidation, reduction, and attack from most corrosives(except hydrofluoric acid, phosphoric acid, and heavy concentrations of alkalies). Water or oil will not damage Gemcolite® shapes. Upon drying, shapes regain their superior physical properties.

Sleeves, insulating boards and wet blankets, and furnace combustion chambers are among the many standard Gemcolite® vacuum formed shapes. Special shapes, specifications, are also available.

Each Gemcolite® vacuum formed special shape requires a unique mold design. Molds are made individually for our plant. Most Gemcolite® special shapes are formed on a male mold. They are made smooth on the inside surface through contact with the mold's screen, while the outside is rough and bark like. However, where desirable, these surface textures can be reversed by utilizing a more elaborate female mold.

Technical support for refractory and heat transfer solutions is available free of charge upon request. Custom formulations in organic and inorganic binder compositions is available for use temperatures up to 3000°F.
