• DESCRIPTION
High density ceramic fiber board is manufactured from high-purity aluminum silicate, primarily alumina and silica. The raw materials are melted at temperatures above 2000°C and transformed into fibers through high-speed gas flow. Inorganic binders are then added, and the board is formed through a wet vacuum-forming process followed by high-temperature pressing.
Compared with standard ceramic fiber boards, ceramic fiber board high density 2300F offers greater rigidity, mechanical strength, and dimensional stability for demanding high-temperature applications. Common high density ceramic fiber boards typically have densities above 300–400 kg/m³, while some specialized grades can reach 600–900 kg/m³.
As a professional high density ceramic fiber board manufacturer and high density ceramic fiber board supplier, Mindelun provides customized high-density ceramic fiber boards for industrial furnaces, kiln linings, thermal insulation, and other refractory applications. Our high density ceramic fiber board China supply solutions are available in different densities, thicknesses, and sizes according to customer requirements.
• PROPERTIES
Ø High temperature resistance and strong thermal stability: The long-term service temperature can reach 1000–1400℃ (depending on the material grade), resistant to thermal shock, and not prone to cracking when subjected to rapid heating and cooling;
Ø Low thermal conductivity + low heat capacity: With a heat capacity only 1/10 that of lightweight refractory bricks, resulting in significant energy-saving effects;
Ø Good chemical stability: Resistant to acids and alkalis, resistant to wind erosion, and not easily penetrated by molten non-ferrous metals;
Ø Lightweight, sound-absorbing, and convenient for construction.
• APPLICATION
Ø Industrial kilns: Inner lining / backing insulation for steel rolling heating furnaces, ceramic shuttle kilns, and petrochemical cracking furnaces;
Ø High-temperature equipment: Insulation layers for heat treatment furnaces, glass furnaces, and aluminum electrolytic cells;
Ø High-temperature seals / gaskets, expansion joint fillers, fireproof isolation barriers, etc.
