Description of ceramic fiber board
Ceramic fiber board is a high-temperature refractory material, usually made of a mixture of ceramic fibers and some inorganic additives. Ceramic fiber board has a flat surface, accurate size, good strength, can be cut at will, uniform inside and outside, and has good thermal insulation properties, which is an ideal insulation material for various industrial furnaces.

Advantages of Ceramic Fiber Board
The boards have excellent strength, maintaining their characteristics and appearance for a long period of time. They are resistant to wear, ageing and degradation and can be used for a long time in harsh operating conditions.
Ceramic fiber board has good thermal insulation properties and can effectively reduce heat transfer and thermal radiation. It stops heat transfer, insulates hot and cold rooms, and improves energy efficiency.
The boards are relatively light compared to traditional fireproof materials, making them easy to handle and install. Despite their light weight, they are strong enough to withstand mechanical stress and vibration.
Ceramic fiber boards have good resistance to many acids, alkalis and chemicals. They are not subject to corrosion and erosion and can be used for a long time in aggressive environments such as acids and alkalis.
Ceramic fiber sheets can be cut, bent and shaped to create a variety of complex surfaces and structures. They can meet the needs of applications of various shapes and sizes.
