Ceramic Fiber Board (MWOOL – BOARD) is made of high-purity ceramic fibers with a small amount of binders, by vacuum forming. It can still maintain good mechanical strength in a hot state.
MWOOL – BOARD doesn’t contain asbestos, with uniform bulk density and thickness, and a smooth surface. It has low thermal conductivity, shrinkage, and thermal capacity. At the same time, it can directly contact with flames and has excellent thermal stability, thermal shock resistance, and airflow erosion resistance. In addition, it has good stiffness and bending strength, and is self-supporting. The volume density is relatively low, making it easy to cut or machine.
MWOOL – BOARD is chemically stable and resistant to most aggressive chemicals (except phosphoric acid, hydrofluoric acid and strong alkalis).
MWOOL – BOARD hydrophobic vacuum forming ceramic fiber board after special process treatment with good hydrophobic performance in the construction process and high moisture conditions.
Typical Applications:
• Backing insulation of Glass tempering furnace, hot bending furnace, annealing furnace and molten pool;
• The lining and fire baffle of thermal equipment such as tunnel kiln, roller kiln and shuttle kiln in ceramic industry;
• Electric furnace hot surface and backing insulation material;
• Aluminum industry hot face and backing insulation material;
• Insulation of thermal equipment in metallurgy, machinery, chemical industry, optoelectronics, environmental protection and other industries;
• Other areas that require a certain level of mechanical strength for self-supporting, insulation, and high-temperature resistance.
