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

Ceramic Fiber Paper is a lightweight refractory material processed from a blend of alumina-silica fibers into a flexible, uniform sheet. The distribution of the fibers with the organic bond and the thickness of the ceramic fiber paper can be very strictly controlled. The bond will be completely burnt out in use.

DITA ceramic fiber paper features light weight, structure uniformity and low thermal conductivity, which serve as a perfect solution for high temperature insulation, chemical corrosion resistance, and thermal shock resistance. Refractory ceramic fiber paper is very flexible and easy to cut with a smooth surface. Ceramic fiber paper can be used in various types of refractory and sealing applications

Key Features
