Product Introduction of Polycrystalline Mullite Fiber Veneer Block:
Polycrystalline mullite fiber is the latest ultra lightweight high-temperature refractory fiber at home and abroad. It is one of the entire Al2O3-SiO2 ceramic fibers, with a service temperature of 1500-1600 ℃, which is 200-300 ℃ higher than glass fibers. It can be widely used for lining insulation of high-temperature industrial kilns and other thermal equipment in metallurgy, ceramics, machinery, chemical industry, electronics, aerospace, etc., in order to achieve energy conservation and increase production, extend the lifespan of the furnace body, and improve the working environment. The appearance is white, soft, smooth and elastic, just like Cotton wool.

Polycrystalline mullite fiber is a kind of polycrystalline refractory fiber with unique structure in the form of mullite crystal phase. It has high technology content and complex manufacturing process. Only a few developed countries can produce this product abroad, such as ICI (Tata Chemicals Europe) in the United Kingdom, Silicon Carbide in the United States, Japan, Germany and other companies. Polycrystalline mullite fibers are prepared using a chemical colloid method, and the resulting fiber cotton (loose) can be used as a filling material for high-temperature interlayers. PMF fiber series varieties, such as boards, bricks, felt, standard prefabrication, modules, composite components, etc., can be produced by wet vacuum forming the loose cotton.
Application scope:
Can be used as furnace wall lining; Heat treatment furnace, heating furnace; Fast firing kiln for ceramics;
The closure of furnace doors and covers, soaking pits, ethylene cracking furnaces, and thermal equipment related to industries such as metallurgy, machinery, chemical engineering, ceramics, electronics, etc.

High temperature resistance: The product has excellent high temperature resistance, excellent resistance to hot melt penetration, and can provide good insulation and heat resistance in limited spaces
Good toughness: uniform thickness, flat surface, able to maintain excellent tensile strength even after long-term use in oxidizing environments
Sound absorption and shock absorption: The material is made by a special process, and the finished product is soft and has certain sound absorption and noise reduction functions
