Low heat loss and reduced heat storage increases furnace efficiency for lower operating costs Resistance to thermal shock

REFRACTORY CERAMIC FIBER INSULATION PRODUCTS

Ceramic fiber is a lightweight insulating product. It has low thermal mass which means that it does not retain heat, low thermal conductivity and is an extremely effective insulation material.

DITA ceramic fiber product family is a group of lightweight, thermally efficient ceramic fiber insulating materials that combine the advantages of dimensional stability at high temperatures with complete resistance to thermal shock. Featuring a broad range of thermal capabilities and physical characteristics, this product family provides proven and effective solutions to a variety of heat processing applications.

DITA Ceramic fiber is available in many forms and densities including:

Ceramic Fiber Blanket

Ceramic Fiber Board

Ceramic Fiber Modules

Ceramic Fiber Paper

Textiles rope and braid

With a temperature range of 1260 C for standard and 1360 C for Hot Face and 1430 C for Zirconium blanket most applications can be easily accommodated.

Product Family Characteristics

• Excellent handling strength

• Excellent hot strength

• Low thermal conductivity

• Low heat storage

• Light weight

• Resiliency

• Thermal shock resistance

• High heat reflectance

• Excellent corrosion resistance

• Excellent thermal stability

• Excellent sound absorption

• Excellent fire protection

DITA ceramic fiber modules utilize a spun ceramic fiber blanket featuring high tensile strength for superior resistance to mechanical abuse and vibration. A proprietary fiber treatment decreases fiber dusting and irritation while increasing block flexibility, making the module easy to compress into place. Ceramic Fiber Module linings prevent heat loss, increasing the furnace productivity and reducing maintenance costs.

Modules are available in 5 grades based on temperature:

1100C Common,

1260C Standard,

1260C High Pure,

1360C High Aluminum,

1430C Zirconium
